Global crash point
One crash multiplier per round for the whole table. Your timing is personal, the crash is not.
Auto-cashout
Lock a target multiplier before the round starts. Same EV as manual, less missed clicks.
Why Crash
One number, one decision window
Crash strips blackjack-style decisions down to a single question: when do you take profit? The crash point is drawn before the animation runs. You cannot influence it. You can only choose a cash-out target and bet size. That makes Crash high variance by design: 2× targets hit often, 20× targets hit rarely, but the expected return per dollar wagered stays at 99 cents over a huge sample.
Instant crashes at 1.00× happen about 1% of rounds. That is not a bug. It is part of the published RTP. Auto-cashout at 1.01× still loses on those rounds.
How to play
How Crash works
Place a bet before the round starts. The multiplier rises from 1.00× and grows on a smooth curve. At a random point the round crashes, if you cashed out before the crash, your bet is multiplied by the value at cash-out time. Auto-cashout lets you lock a multiplier in advance (e.g. 2.00× = 2× return triggered automatically).
Multiple players can bet the same round. Everyone sees the same curve and the same crash multiplier. Two players with different cash-out targets can win and lose on identical crash points.

Strategy
Cash-out target vs. expected value
The expected value of any cash-out target is identical (99 cents on the dollar), what changes is variance. Cashing at 1.50× hits ~66% of the time and turns small profits into a flat curve. Cashing at 10× hits ~10% of the time but each win is a 10× multiplier of your stake. Fixed-fraction sizing (1-2% of bankroll per round) and a hard stop-loss are the only meaningful protection against tail-risk.
Every cash-out target has the same 99% EV. Pick the target that matches how much swing you want in an hour, not the one that "feels due." Fixed 1-2% of bankroll per round and a hard stop-loss beat any progression script.
Provably fair
How to verify a Crash round
The crash point is derived from HMAC-SHA-256 of the seed pair plus nonce, mapped through a public formula that gives a 99% RTP target distribution. The seed pair is published the moment the round resolves, recompute and confirm the crash multiplier independently.

Crash reference: RTP, cash-out targets, verification
Everything about Duel Crash: how the multiplier works, why instant crashes exist, auto-cashout, bankroll math, and how to verify the crash point after any round.
What it is
Crash is Duel's multiplier curve game in the Originals lobby. A round starts at 1.00× and rises until a random crash point ends it. Players who cashed out before the crash keep stake × multiplier. Everyone else loses the bet.
RTP and house edge
House edge is 1% (99% RTP). The distribution includes instant 1.00× crashes and long tails above 100×. No cash-out target changes long-run EV. Targets only change variance.
Bankroll and sessions
Crash eats bankrolls through tail risk, not edge alone. Cashing at 10× means long dry spells. Size bets at 1-2% of session bankroll, set a stop-loss in dollars, and quit when you hit it. Chasing a loss with bigger bets does not move the 1% edge.
Vs other Originals
Versus Dice, Crash removes the probability slider but adds a live timing element. Versus Mines, Crash is one decision per round instead of many tile picks. Both run at 99% RTP with very different variance shapes.
VIP and promos
Crash counts toward VIP wagering. Slot rakeback does not apply. Weekly cashback on net loss can include Crash play.
Crash FAQ
All originalsIs there a strategy that beats Crash?
No. The 1% edge is fixed in the crash distribution. Bet sizing changes variance, not return. Any system claiming to flip EV is wrong.
What is auto-cashout?
A multiplier you set before the round. If the curve reaches it before crashing, you cash out automatically. Same EV as clicking manually.
Can the round crash at 1.00×?
Yes, about 1% of rounds. Part of the published RTP. Even auto-cashout above 1.00× loses on instant crashes.
Do all players see the same crash point?
Yes. One global crash per round. Individual results depend on when each player cashed out.
Does a higher cash-out target have better EV?
No. All targets converge on 99% RTP over volume. Higher targets pay less often but pay more when they hit.
Can I play Crash on mobile?
Yes. Same RTP, same provably fair tools, touch-friendly cash-out button.
What is the max win on Crash?
Table cap applies to stake × multiplier. Check in-game limits before confirming a bet.
Does Crash count toward VIP?
Yes. Originals wagers count at 0.5× toward VIP tier progress. Weekly cashback on net loss can apply at tiers from 5% to 20%.
