The gambler's fallacy and other crash game biases

The gambler's fallacy is believing an outcome becomes more likely because it hasn't happened for a while. "It's crashed low ten rounds in a row, a big multiplier is coming." It's the most widespread mistake in gambling, and a crash game triggers it every round.

Rounds are independent

In a fair crash game, each round has its own draw. In Pothole, for example, each round gets a new 32-character seed drawn at random on the server (see provably fair). The game keeps no memory of past rounds and has no "average to catch up on".

On the Expressway, the chance that the pothole sits at the first km is 37.8%. Here's what that looks like in streaks:

Five crashes at km 1 in a row is rare (under 1%), but once it's happened, the next round has exactly the same chance as any other: 37.8%. The rarity of the streak doesn't carry over to the next round. The most cited example goes back to 1913 at the Monte Carlo casino: black came up 26 times in a row at roulette, and players lost heavily betting on red, convinced it was "due".

The other mental traps

• The hot hand. The flip side: "I'm on fire, I'll keep going." Three wins in a row don't change the odds of the fourth.
• The near miss. A crash at 9.80× when you were aiming for 10× feels like you "almost" had it. In fact you lost like any other time, but the brain reads it as encouragement to play again.
• The illusion of control. Your tapping rhythm, the time of day, your "routine": none of it affects a draw made on the server before your first move.
• Chasing losses. After a loss, raising the stake or the target to win it all back. That's the basis of the martingale, and the strategy page shows where it leads.
• Patterns in the history. Screens show recent results in colour; the eye sees cycles. They're coincidences, and exactly what predictors exploit.

How to protect yourself

• Decide before you play: your stake, your target and your stop. Decisions made mid-game are the ones biases control. See bankroll management.
• Tell yourself the right sentence: "the next round has the same odds as all the others."
• Look at the numbers, not the history: a game's probabilities don't move from one round to the next.
• Stop when you catch yourself thinking "it's due". That's the signal.
