All-in (double or nothing): entire bankroll every spin — tested to destruction
94% BUST — THE EDGE, WEAPONIZED⚙ computed
We ran 200,000 sessions of All-in (double or nothing) ($5 base on red, $500 bankroll, $500 table max, 100 spins, European wheel). Result: 94.3% of sessions busted, the median player finished at $0, and the realized house edge was 2.71% — statistically identical to the wheel’s 2.70%. A maximum variance: it reshapes how you lose, never how much on average.
The distribution — what 200,000 bankrolls did
| Metric | Value | Read it as |
|---|---|---|
| Bust rate | 94.3% | sessions that hit $0 within 100 spins |
| Hit the table max | 48.8% | the cap the system pretends doesn’t exist |
| Median finish | $0 | the typical session — wiped out |
| 10th / 90th percentile | $0 / $0 | the bad night vs the good night |
| Mean finish | $326 | the average — always below $500, by exactly the edge |
| Avg max drawdown | $1333 | the hole you sit in along the way |
| Avg spin of ruin | #8 | when busts happen, this is when |
| Realized edge | 2.71% | vs the wheel’s 2.70% — the punchline |
Change the conditions — the price stays

Frequently asked
Does the All-in (double or nothing) system work?
Not against the edge. Over 200,000 sessions it paid the wheel 2.71% of all money wagered — the same price as betting randomly. It does concentrate losses brutally: 94% of bankrolls died within 100 spins.
What bankroll does All-in (double or nothing) need?
Doubling the bankroll to $1,000 moved the bust rate from 94.3% to 88.5% in our runs — a real reduction in bust risk, purchased with more money at the same percentage price.
Is All-in (double or nothing) good for short sessions?
At 50 spins the bust rate was 91.0% (vs 94.3% at 100). Shorter exposure means fewer disasters and less edge paid — which is true of every system, because time on the felt is the only variable that matters.
