Does Martingale work?
Martingale means doubling your stake after every loss so that one win recovers all earlier losses plus one base unit. It does not change the house edge. It trades many small wins for a rare, very large loss.
On a roll with a 49.50% win chance, a loss happens about 50.5% of the time. With a $1 base stake:
| Losses in a row | Stake on the next bet | Total lost so far |
|---|---|---|
| 3 | $8 | $7 |
| 7 | $128 | $127 |
| 10 | $1,024 | $1,023 |
Probability of 7 losses in a row from the start is about 0.8% (0.505 to the 7th power), and of 10 in a row about 0.1%, but over hundreds of bets such runs are likely to occur. Dice sites also have maximum bets and your bankroll is finite, so at some point you cannot double again.
What other systems exist?
- Paroli (positive progression): you double after a win and return to the base stake after a loss or a set number of wins. Losses are small, and one loss ends a winning run.
- Flat betting: you bet the same amount every roll.
- Others (D’Alembert, Fibonacci, “patterns”): they change the shape of your results, not the expected loss.
Nothing in past rolls predicts the next one, and every roll is independent. You can check the roll integrity of a site with the verification guide, but that proves fairness, not a winning system.
What is risk of ruin?
Risk of ruin is the chance that you lose your whole bankroll before you stop. It rises with bigger stakes relative to your bankroll, with progressive systems like Martingale, and with the number of bets. Flat betting lowers risk of ruin compared with progressive systems at the same edge, because you never escalate your stake after a loss.
How much bankroll per roll?
A common rule of thumb is 1% of your bankroll or less per roll. With a $500 bankroll that is $5. It is not a guarantee, and any bet can lose. At a 1% edge, wagering $10,000 loses an expected $100; at 5% it loses $500 (see house edge explained). Choose a bankroll you can afford to lose completely, and do not top it up after a loss.
Can you beat a dice site long term?
With a positive house edge, no. Over a large number of bets your result approaches the edge times your total wagered. Short-term winners exist because of luck, and they usually give it back if they keep playing. The best choice for your wallet is lower stakes, fewer bets and a site with a lower edge. Compare edges in our ranking and read the evidence in each review such as CSGO500.
What habits protect you?
- Set a deposit limit and a loss limit before you start.
- Take breaks and use reality checks where available.
- Do not chase losses, and do not stake skins you want to keep.
- Walk away when you hit your limit.
Risk: If you notice chasing losses, hiding gambling or staking items you meant to keep, stop and read responsible gambling for warning signs and free help. Also see are CS GO dice sites legal and safe.
