JetX Casino Game UK 2026: The Complete Guide to Crash Gaming
JetX isn’t a slot. It doesn’t care about paylines. You won’t find a bonus round with dancing leprechauns. This is a crash game—one that’s been splitting opinions faster than a dodgy WiFi signal at a live dealer table. Since its release by SmartSoft Gaming, JetX has carved a niche among UK players who want something that moves at their own pace, with a multiplier that climbs like a startled cat and a cash-out button that tests your nerve. The game’s premise is almost insultingly simple: a jet takes off, the multiplier rises, and you cash out before it explodes. Miss the exit and your stake vanishes—poof. No second chances. No “just one more spin” autoplay to cushion the blow.
In 2026, the UK iGaming scene has seen crash games shift from curiosity to staple. JetX leads the pack, partly because it’s available across a weird mix of UK-licensed operators and offshore crypto joints. That split matters. Licensed casinos impose GameSense tools, deposit limits, and a slower pace. Offshore sites dangle bigger crypto bonuses and less red tape. Both types exist in the same player’s bookmarks. This guide won’t preach about which is better—it’ll lay out how the game works, where to play it, and what to expect when you’re watching that little jet weave across the screen. No glitter. No “win big today” nonsense. Just the facts, a few raised eyebrows, and a ranking table that puts some meat on the bones.
What Actually Is JetX?
JetX is a multiplayer crash game. You place one or two bets before each round, then watch a cartoon jet fly across a grid. A multiplier starts at 1x and climbs. The jet can crash anywhere between 1.01x and some mythical ceiling—SmartSoft claims no maximum multiplier, but in reality it rarely passes 100x. Your job: hit cash out before the jet explodes. Cash out too early and you leave money on the table. Wait too long and you get nothing. It’s a pure test of greed versus discipline, wrapped in a cheery 3D animation that looks like a mobile game your nephew would play.
Under the hood, the outcome is determined by a provably fair random number generator. Each round’s crash point is pre‑computed and hashed, so you can verify that the casino didn’t nudge the jet into a cliff just because you doubled your stake. This transparency has become a must‑have in crash gaming, and JetX delivers it. The game also displays recent round history in a live feed, showing other players’ cash‑outs and the occasional “OMG 47x!” reaction. Whether that adds tension or just clutter depends on your personality.
Visually, JetX is uncluttered. A blue sky, a jet with a vapour trail, a multiplier counter, and two bet panels. No reels, no wilds, no soundtrack that makes you want to mute the tab (though you can mute it). It loads quickly on mobile and desktop, which is a plus given that crash games rely on split‑second timing. Lag is your enemy here more than any house edge.
How to Play JetX Without Looking Like a Lemming
Playing JetX takes less time to learn than ordering a coffee. But playing it well—or at least not stupidly—requires a grip on the controls and a few mental rules.
First, you set your bet amount. Two bet panels sit side‑by‑side, letting you run two independent strategies in one round. You might set Panel A to auto‑cash at 2x for a steady grind, and Panel B at 5x for a longer shot. Or you can use just one bet. After placing, you wait for the countdown. The jet takes off. The multiplier ticks up in hundredths. You can cash out manually by clicking the button, or pre‑set an auto‑cash multiplier. If the jet crashes before you cash out, the bet is lost.
The game also offers an auto‑bet function, which will repeat your last bet configuration round after round. It’s handy but dangerous—set it, forget it, and come back to a balance that’s either surprisingly plump or depressingly thin. The interface shows your profit on the current round, and a side panel tracks recent rounds. One oddity: you can’t cash out both bets at once. You have to tap each panel separately. In a frantic round where the multiplier is screaming past 10x, that split‑second fumble can cost you.
For newcomers, the demo mode is a gift. You get a fake balance, no registration, and the exact same RNG behaviour. Use it to understand the rhythm: the multiplier doesn’t rise linearly; it accelerates slightly as it goes, which can trick your brain into thinking a crash is imminent when it isn’t.
Where to Play JetX in the UK: A 2026 Operator Breakdown
The UK online casino market is a two‑tier beast. Tier one: UKGC‑licensed sites that must follow strict rules on bonuses, verification, and player protection. Tier two: offshore casinos that hold Curacao or other licences and accept UK players via VPN or lax geo‑fencing. Both tiers host JetX, but the experience differs wildly in bonus terms, withdrawal speed, and the general vibe. Below is a comparison of eight operators—four licensed, four offshore—that were live and actively offering JetX in early 2026. Every brand listed is real and recognisable; no anonymous “Casino A” nonsense here.
| Casino / Operator | Bonus for JetX Players | Licence | Min. Deposit | Withdrawal Speed | Standout Feature |
|---|---|---|---|---|---|
| BetVictor | Welcome free spins package (JetX eligible) | UKGC | £10 | 1–2 days | Reputable UK heritage, fast payouts |
| Mr.Play | 100% up to £200 + 20 free spins | UKGC | £10 | 2–3 days | Extensive game library, mobile‑first design |
| PlayOJO | 50 free spins on first deposit (OJOplus rewards) | UKGC | £10 | 1–3 days | No wagering requirements on spins |
| Casumo | 100% up to £100 + 30 free spins | UKGC | £10 | 1–2 days | Gamified loyalty system, strong UX |
| Stake | Daily races & weekly giveaways (crypto) | Curacao | $20 crypto | Instant (crypto) | Provably fair originals, massive community |
| BC.Game | Up to 180% first deposit bonus | Curacao | $10 crypto | Instant (crypto) | Vibrant social features, custom crypto |
| Duelbits | Rakeback on crash games | Curacao | $10 crypto | Instant (crypto) | Sleek interface, duel system |
| 1xBet | 100% up to €300 sports & casino | Curacao | €1 | 1–5 days | Huge game selection, low min deposit |
A quick reality check: the bonuses listed are subject to terms that can make your eyes water. UKGC operators cap wagering at 40x or below, but the “free spins” might only yield pennies. Offshore bonuses often carry 50x or even 60x wagering, and cashing out winnings from a 180% match can feel like trying to squeeze water from a rock. Still, if you’re going to play JetX anyway, picking a site that gives you some extra ammo isn’t a crime—just don’t mistake a “gift” for charity. Casinos don’t run food banks.
For UK players who value consumer protection, the UKGC quartet—BetVictor, Mr.Play, PlayOJO, Casumo—are the safer harbour. They force ID verification early, offer deposit limits, and have a clear complaints process. The offshore crowd wins on bonus size and crypto flexibility, but if a dispute arises you’re essentially on your own. Choose your poison.
JetX Demo Mode: The Zero‑Risk Training Ground
Demo mode isn’t a “free bonus”. It’s a functional replica of the real‑money game with no financial stake. You get a virtual balance, usually 1,000 to 5,000 units, and the same RTP and crash distribution. No registration is needed on most casinos. This is where you learn that manual cash‑out requires reflexes of a fruit fly, and that auto‑cash at 1.5x is boring but consistent. The demo also lets you test the double‑bet feature: one panel cashing at 2x, the other riding longer. Watching both bets evaporate in a crash at 1.03x is a humbling experience.
UK operators generally place demo mode behind an account login, a side‑effect of the Gambling Commission’s age‑verification rules. Offshore sites are looser—often you can launch the demo straight from the game thumbnail. If you’re just scouting the game’s feel, the offshore path is faster, but then you’re one click away from a real‑money deposit screen that expects you to be weak. And they know you probably are.
Playing JetX for Real Money: What Changes
The moment you switch from demo to real cash, the jet doesn’t fly any differently. The RTP stays at 97% (SmartSoft’s official figure). The crash algorithm doesn’t suddenly become vengeful. What changes is your own pulse. Real money introduces loss aversion, and with a game as fast as JetX—rounds last 5 to 30 seconds—you can burn through a deposit in the time it takes to microwave a ready meal. That’s not hyperbole. A £20 balance with £1 bets gives you 20 rounds. At 15 seconds per round, you’re done in five minutes. Poof.
Bet sizing here is everything. The minimum bet is usually £0.10 or currency equivalent, which lets you stretch a modest deposit. But many players bump to £1 or £2 for the adrenaline. A smart approach: allocate no more than 1% of your session bankroll per round. If you’ve set aside £50 for an evening, your base bet should be £0.50. This keeps the game from turning into a slot‑machine speedrun. Also, use the loss‑limit function that UKGC casinos must provide. Set it before you open the game, not after you’ve chased a 15x multiplier that never came.
Withdrawals deserve a mention. At UK casinos, you’ll wait 1–3 business days after verification. At crypto casinos, withdrawals can be near‑instant, but you’ll face network fees and price fluctuations. If you hit a nice cash‑out on JetX and want to bank it, consider converting crypto to stablecoins immediately. Otherwise, that 3x win might become a 2.5x loss by the time you sell.
JetX Strategy: Why Most “Systems” Are Just Fancy Guesswork
Let’s kill the unicorn right now: there is no betting system that beats a provably fair crash game. Not Martingale, not Fibonacci, not some guy on YouTube with a £10,000 challenge. Every round is independent. The RNG doesn’t know you lost three in a row. The jet doesn’t have a memory. That said, some approaches can stretch your playtime and protect your bankroll—but they will not turn the house edge in your favour.
The most common tactic is the low‑multiplier grind. Set auto‑cash at 1.5x or 2x and hope the crash rate stays low. The problem? Crashes below 2x happen roughly 40% of the time (based on community‑tracked data from thousands of rounds). That means you’ll lose two in five rounds even with a low target. Streaks of eight or nine sub‑2x crashes are not rare. If you’re doubling your bet after each loss—hello, Martingale—you’ll hit the table limit or your deposit limit faster than you can say “but the maths says…”.
A more sensible approach is the two‑panel split. Panel A cashes at a safe multiplier, say 1.3x, which covers your total stake for both panels. Panel B rides longer, maybe 10x, as a risky side bet. If Panel A wins, you break even on the round. If Panel B hits, you profit. If both crash, you lose both. Over a large sample, the house edge grinds both panels down, but the ride is smoother. Just don’t convince yourself you’ve “cracked” the game. You haven’t. You’ve just made the losses less jagged.
Another angle some players take is statistical observation—tracking the last 200 rounds and increasing their bet after a long streak of low multipliers, assuming a high multiplier is “due”. This is pure gambler’s fallacy and works until it spectacularly doesn’t. A crash game can happily deliver fifty consecutive crashes under 2x; the math has no quota to fill. If you want to try it, do it with money you’d set on fire for entertainment.
RTP, Fairness, and What the “Provably Fair” Label Means
SmartSoft Gaming publishes JetX’s RTP at 97%. That’s solid, on par with decent slots and better than many live casino bets. But RTP is a theoretical average over millions of rounds. Your session might return 160% or 12%—the variance is huge. The game’s maximum win per round is capped at $10,000 or currency equivalent, which also limits payouts on extreme multipliers (a £100 bet at 200x would exceed the cap, so you’d only get $10k). Not many UK players will bump into that ceiling, but it’s worth knowing.
Provably fair technology is JetX’s trust anchor. Each round’s crash point is generated from a server seed and a client seed, hashed, and revealed after the round. You can verify the hash using third‑party tools or a casino’s own checker. It’s elegant, but in practice, maybe 1% of players ever bother checking. The rest just trust the label. If you’re the suspicious type, most crypto casinos let you set your own client seed, adding a layer of personal verification. UKGC casinos don’t always offer that because their RNGs are audited by testing labs instead. Both methods are legitimate; the difference is transparency vs. regulatory stamp.
JetX on Mobile: A Pocket Rocket That Actually Works
Crash games live or die by mobile responsiveness. Lag? Dead. Clunky tap targets? Dead. JetX, thankfully, runs as a lightweight HTML5 game that loads in under five seconds on a 4G connection. The bet sliders adjust smoothly, and the cash‑out button is large enough that your thumb won’t miss it if you’re playing one‑handed on the bus. The interface rotates to landscape for a wider view, but portrait mode is perfectly usable.
One quirk: on some Android devices, the game can stutter when the multiplier accelerates past 50x, a rare but noticeable micro‑freeze. It’s not a dealbreaker, but if you’re pushing for a monster cash‑out, maybe play on desktop where you’ve got a more stable connection and a real mouse button. That said, mobile data usage is minimal—a few MB per session—so you won’t drain your plan. Not all casinos offer the same mobile smoothness, though. In our operator table, Mr.Play and Stake stand out for their native‑feeling mobile sites, while some smaller Curacao brands still feel like they were optimised for a 2015 browser.
JetX vs. Other Crash Games: Spaceman, Aviator, and the Rest
The crash game shelf is getting crowded. Spribe’s Aviator is the elephant in the room—simpler graphics, a slightly higher RTP of 97.5%, and a massive community. Spaceman by Pragmatic Play offers a similar vibe with a floating astronaut and a 97% RTP. Then there’s F777 Fighter, Zeppelin, and a dozen clones. What sets JetX apart? The double‑bet feature is a genuine differentiator. Most crash games force you into one bet per round. Being able to run two parallel strategies on the same multiplier curve is a tactical edge—not edge over the house, but edge over boredom. It lets you mix safety and risk within one session without switching games.
JetX also has a slightly more polished visual presentation than Aviator, though that’s subjective. The real kicker, though, is availability. JetX appears on more UKGC‑licensed sites than Aviator, partly due to SmartSoft’s distribution deals. So if you’re staying within the UK’s regulated walls, you’re more likely to find JetX on your favourite site. The flip side: Aviator’s community is bigger, so you’ll find more shared strategies and “OMG 100x” clips online. But chasing community hype is a fool’s errand; the game doesn’t care how many people watched.
Legal Status of JetX in the UK: No Need to Hide Your VPN
Crash games are not banned in the UK. In 2026, they fall under the same category as any RNG‑based casino game. The Gambling Commission has not issued any specific prohibition, though it keeps an eye on rapid‑cycling games (a consultation on game speed ran in 2024 but didn’t ban crash games). So playing JetX at a UKGC‑licensed casino is perfectly legal. The only legal wrinkle is that you must be 18 or over and not self‑excluded via GamStop.
Offshore casinos operate in a grey area. They aren’t illegal for UK players to use, but they lack UK oversight. If an offshore site withholds your winnings or goes bust, you won’t get help from UK authorities. Many UK forums report smooth experiences with the Crypto big boys (Stake, BC.Game), but there’s always a risk. For anyone on the fence, the pragmatic advice is: if you want legal protection, stick to UKGC sites and accept the slower payouts and smaller bonuses. If you’re willing to trade protection for crypto‑speed, then offshore is an option—just do your homework and use small amounts.
Common Mistakes That Drain Your Balance
Most JetX losses aren’t caused by bad luck. They’re caused by human error that’s as predictable as sunrise. Here’s a non‑exhaustive hit list.
Chasing the crash. After a few green rounds, some players raise their auto‑cash target “just this once”. A 2x target becomes 5x, then 10x. The jet crashes at 1.14x, and suddenly you’re down three rounds’ worth of profit.
Ignoring the double‑bet panels. Many people set both panels to identical bets and auto‑cash multipliers. That’s just doubling your stake for no benefit. If you’re going to use both, make them serve different purposes.
Playing without a session timer. JetX is so fast that ten minutes feels like two. If you don’t set an external timer or loss limit, you can lose track of time—and money—effortlessly. UKGC casinos let you set reality checks; use them.
Trusting “hot and cold” indicators. The live feed of past rounds can trick you into seeing patterns. The board shows a streak of crashes above 5x, so you start betting bigger. The RNG doesn’t see that streak. It just produces the next number. The feed is entertainment, not strategy.
Bonuses and Promotions for JetX Players: The Fine Print
Most casino bonuses can be used on JetX, but check the terms. Some operators exclude crash games from welcome offers—rare, but it happens. More common: crash games contribute only 10% or 20% towards wagering requirements. So a £100 bonus with 40x wagering means you must stake £4,000 before cashing out; if JetX contributes only 10%, you’d need to bet effectively £40,000 through it. That’s a massive grind, mathematically likely to eat your bonus before you ever see real money. If a site offers a “cashback” on crash games, that’s often more valuable—real losses returned as bonus funds, which you can then play with less harsh wagering (or none, in the case of Duelbits’ rakeback).
Free spin bonuses are the worst fit for a JetX player. You’re forced to play slots you might not enjoy, and the winnings from spins are often capped at £5 or £10. If you’re a crash game purist, ignore free spin offers and hunt for a basic match bonus with reasonable wagering on all games. Even then, treat it as a volume discount on your gambling spend, not a “gift”. Because it isn’t.
JetX Community and Live Interaction
JetX’s in‑game chat is a zoo. You’ll see everything from “GL everyone” to conspiracy theories about the casino rigging the crash when a big bettor leaves. Most of it is noise, but the community feed serves one psychological purpose: it shows you’re not alone. When the multiplier hits 50x and you weren’t in, watching twenty players post “CASHED 50x!” is a new form of tilt. Some players use the chat to coordinate “ride strategies”—everyone cashing at the same multiplier for a shared win. It’s harmless fun but doesn’t affect outcomes.
On the serious side, dedicated JetX communities exist on Discord and Reddit, where players share verified seeds, discuss RTP tracking, and occasionally reveal actual profit‑loss sheets. One German player tracked 10,000 rounds and found an RTP of 96.8%—close enough to the theoretical figure to confirm fairness. Reading those logs can sober you up faster than any responsible gambling banner.
Advanced Features: Auto‑bet, Scripts, and What’s Allowed
Auto‑betting is built in, but players have asked about external scripts for automated cash‑out. SmartSoft’s terms prohibit any software that interacts with the game beyond the standard interface. Casinos can (and do) confiscate winnings if they detect bot usage. Moreover, scripts that “read” the multiplier could be flagged as cheating. The game is designed to be played manually or with the provided auto‑cash. If you need a bot to play a game that has two buttons, you’re probably overthinking it.
That said, some players use simple browser macros to click the cash‑out button more reliably. A macro that hits the button at a set multiplier is hard to detect but also unnecessary—just set auto‑cash. The real risk is using a martingale bot that doubles bets after losses; those violate terms and can get you banned. Play within the rules, or don’t complain when your account gets locked.
Payment Methods for UK JetX Players
How you fund your JetX session affects speed, privacy, and fees. Below is a quick comparison of common UK payment channels and their relevance to crash gaming.
| Method | Deposit Speed | Withdrawal Speed | Fees | Notes |
|---|---|---|---|---|
| Debit Card (Visa/Mastercard) | Instant | 1–3 days | Free (bank may charge on withdrawal) | Widely accepted, but some declines due to bank blocks |
| PayPal | Instant | Up to 24 hours | Free | Available at UKGC sites only; offers chargeback ability |
| Trustly / Open Banking | Instant | 1–2 days | Free | Secure, no registration; growing in UK |
| Skrill / Neteller | Instant | Within hours | 1-3% per transaction | Accepted at many sites; ewallet fees apply |
| Cryptocurrency (BTC, ETH, etc.) | Minutes | Instant (offshore) | Network fees | Only at offshore casinos; volatile value |
| Paysafecard | Instant | Cannot withdraw to | Deposit fee may apply | Good for deposits; must use alternative for cashout |
For JetX, speed matters because you might want to deposit quickly if a session goes south (not recommended, but realistic) or withdraw fast after a big hit. PayPal and e-wallets offer the best balance of speed and convenience within UKGC sites. Crypto is the king of speed offshore, but you need to know your wallet from your elbow. If you’re new to this, debit card is the path of least resistance—just expect a wait on withdrawals.
Responsible Gaming with Crash Games: A Necessary Chore
Crash games are engineered for rapid consumption. The rounds are short, the feedback loop immediate, and the temptation to “just one more” overwhelming. Responsible gaming tools are not annoying pop‑ups—they’re what keep a hobby from becoming a problem. All UKGC casinos must offer:
- Deposit limits (daily, weekly, monthly)
- Reality checks (timer‑based notifications)
- Time‑outs and self‑exclusion (including GamStop integration)
- Session loss limits
Set these before you open JetX. Don’t wait until you’re chasing a loss. The game’s design—with its clear cash‑out button—makes it easy to track what you’re risking per round, which is a small advantage over slots that bleed you slowly. Use that clarity to set hard stops. If you can’t stick to them, consider a permanent self‑exclusion. No multiplier is worth your rent.
Offshore casinos have fewer mandatory tools, but many voluntarily offer similar features. Stake has a “Vault” system to lock funds away; BC.Game has session limits in beta. Don’t rely on the casino to protect you—take the few minutes to set your own boundaries.
JetX in the UK: Future Trends and What 2026 Might Bring
Regulatory pressure is the elephant in the room. The UKGC’s ongoing review of game speed could introduce a mandatory round delay—maybe five seconds between bets—to slow down cycle times. That would upset JetX’s appeal but align it with the Commission’s harm‑reduction agenda. Another possible shift: stricter enforcement against offshore operators via payment blocking. If UK banks start blocking crypto‑to‑casino transfers, the offshore scene could shrink. That would push more players to UKGC sites, which would then need to improve their crash game bonuses to compete.
On the product side, SmartSoft has hinted at a JetX sequel with social features and tournament modes. If they deliver, expect a wave of “JetX 2.0” coverage by mid‑2027. For now, JetX remains a solid, no‑nonsense crash game that does what it says on the tin. It won’t make you rich. It might entertain you for an hour. And it will definitely punish you if you forget to press the button.
Real‑World JetX Sessions: A Typical Evening
Imagine a Thursday night. You deposit £30 at BetVictor, open JetX on your phone. You set a £0.50 auto‑cash at 2x, and a second bet of £0.20 with a manual cash‑out. Round one: crash at 1.17x, both bets lost. Round two: you manually cash the smaller bet at 3.2x, the auto‑bet hits 2x. You’re up £0.90. Five rounds later, you’ve hit eight auto‑cashes, profit of £2.00. Feels steady. Then a streak of four crashes under 1.5x, and you’re down £1.80. You switch the manual bet to auto‑cash at 5x. Round fifteen: the multiplier climbs—3x, 5x, 10x—you’re watching, palm sweaty. It crashes at 1.09x. You lose both bets. Now down £3.70. You log off. This is a normal session. It’s not thrilling, not devastating. It’s a slow erosion with occasional spikes. That’s the real face of JetX.
The lesson: Nobody posts about losing £3.70 on a Thursday. Social media shows the 250x screenshots, not the hundreds of 1.02x crashes. If you go in expecting fireworks, you’ll be disappointed. If you go in expecting a gentle burn, you’ll be realistic.
JetX and the Illusion of Control
Crash games sell control. You decide when to cash out. You can set auto‑cash. The outcome feels skill‑based. It isn’t. The crash point is determined the moment the round begins, and no amount of timing changes it. The only decision you make is when to exit, which affects your profit or loss but doesn’t influence the crash point. Psychologically, that illusion of agency is powerful—it’s what keeps players engaged longer than a slot spin. They think, “Maybe next time I’ll hold a millisecond longer.” You might, and you might win, but the house edge remains at 3% regardless of your cash‑out timing.
So play JetX if you enjoy the tension. Play it if you like the visual feedback. But don’t mistake the cash‑out button for a steering wheel. When you’re in control of a crash, you’re not driving the jet—you’re just deciding when to jump off the wing.
Is JetX rigged?
No, JetX is not rigged. It uses a provably fair algorithm audited by independent testing labs. The RTP is 97%, meaning the house has a 3% edge, exactly as disclosed. The game’s outcomes are deterministic from the moment the round starts; you can verify the hash after the round to ensure no manipulation occurred.
Can I play JetX on mobile in the UK?
Yes, JetX is fully optimised for mobile play. The HTML5 framework ensures smooth performance on iOS and Android browsers. Most UK casino sites load the game within seconds, and the tap targets are sized for touchscreens. A stable internet connection is recommended to avoid lag during critical cash‑out moments.
What’s the best strategy to win at JetX?
There is no guaranteed winning strategy, as rounds are independent. However, a popular approach is cashing out early at low multipliers like 1.5x–2x. This reduces variance but doesn’t overcome the house edge. The two‑bet panel method can also protect your balance by splitting a safe bet and a riskier one.
How do I cash out winnings from JetX in the UK?
Cash‑out is straightforward. After a win, funds appear in your casino balance. Withdrawals are processed through standard casino methods—debit cards, PayPal, Skrill, etc. UK‑licensed casinos typically process withdrawals within 1–3 days after verification. Offshore casinos offer faster crypto withdrawals, often within hours.
Is JetX legal in the UK?
Absolutely. JetX is legal when played at UK Gambling Commission‑licensed casinos. The game is classified as an RNG‑based casino game and complies with UK regulations. Players must be 18 or older. Playing at offshore, non‑UK casinos is not illegal but lacks UK consumer protections.
What is the maximum multiplier in JetX?
There is no publicly stated maximum multiplier; SmartSoft hasn’t published an upper limit. In practice, multipliers above 100x are extremely rare. The game also has a win cap of $10,000 per round, so even if the multiplier reaches 500x, large bets may be capped. Community records show rare instances above 1,000x, but these are outliers.
