CRASH

OVERVIEW

Crash is a multiplier game where the round starts at 1.00x and rises until a random crash event ends it.

SETUP

• Choose your bet amount.
• Choose your auto cashout target C (for example, 2.00x).

ROUND FLOW

• The multiplier increases continuously from 1.00x upward.
• If the round crashes before reaching your target, the bet loses.
• If the multiplier reaches your target before crash, the round cashes out and you win.

PAYOUT LOGIC

Your target controls hit rate and payout tradeoff:

• Lower target -> higher hit rate -> lower win size.
• Higher target -> lower hit rate -> higher win size.

GAME MATH

Crash can be modeled using a fixed auto cashout target.

PARAMETERS

PROBABILITY OF WINNING AT TARGET C

NET RESULT PER ROUND

If the round reaches target C, net win is (C - 1) * bet_size.

If the round crashes before C, net result is -bet_size.

EXPECTED VALUE

Substituting the probability formula gives:

This means the player's expected return per round is:

PROVIDER COMPARISON

RAKEBACK ADJUSTMENT

If rakeback returns a fraction r of house edge, effective edge is:

With Duel's 100% rakeback (r = 1), modeled effective edge is 0%.

You can test any auto cashout from 1.01x to 1,000,000x in the simulator below.

VOLATILITY / STD

Each auto-cashout target creates a binary outcome (hit target or lose bet):

At 2.00x with Duel edge 0.10%:

At 10.00x with Duel edge 0.10%:

At 50.00x with Duel edge 0.10%:

Higher auto-cashout targets increase SD quickly.

WARNING

Strategies are methods of shaping your risk and payout profile, not ways to beat the house.

They can be used to:

• Smooth variance and generate more frequent, smaller wins.
• Increase variance to chase larger, less frequent payouts.

This means each wager has a negative expected value, or neutral when playing zero-edge, and changing bet sizes or betting patterns won't change that.

MARTINGALE STRATEGY

Increase bet size after losses (typically doubling) to recover all previous losses plus a fixed profit. This works extremely well until it doesn't and all of your bankroll is gone.

Bet size sequence: b, 2b, 4b, 8b, ...

Stop when a win occurs, then reset to base bet.

Martingale — Distribution Effect

• Very high win frequency.
• Many small profits.
• Rare but extreme losses (one big loss can drain your bankroll).

PAROLI (INVERSE MARTINGALE)

Bet sequence after wins: b, 2b, 4b, ...

Reset to base bet after a loss.

Paroli — Distribution Effect

• Lower win frequency.
• Many small losses.
• Occasional large wins.
