What is a CS:GO dice game?
A CS:GO dice game is a betting game where the site draws a number from 0.00 to 100.00 and you bet on which side of a target it lands. Players still say “CS:GO dice” even though the current game is CS2; we explain the name in CS:GO dice vs CS2 dice. The dice are digital. There is no physical die, only a random number and a payout rule.
Some sites also offer a player-versus-player variant called Dice Duels. This guide covers the standard single-player roll.
What does roll over and roll under mean?
Roll Over and Roll Under set which side of the target wins. They are two ways to bet on the same number line.
- Roll Over wins when the roll is above your target. A target of 50.00 wins on 50.01 to 100.00.
- Roll Under wins when the roll is below your target. A target of 50.00 wins on 0.00 to 49.99.
Win chance follows directly. For Roll Over, win chance is 100 minus the target. For Roll Under, win chance equals the target. Try the slider below to see the win zone (green) and lose zone (red) move.
How do you win?
You win when the roll lands in your green zone. You choose a direction, move the target, and roll. The payout is your stake times the multiplier, and a losing roll costs the stake.
A narrow win zone is harder to hit and pays more. A wide win zone hits often and pays less. Neither changes the expected outcome over many bets, because the house edge is built into the multiplier.
How is the payout calculated?
The multiplier equals 100 minus the house edge, divided by the win chance (both in percent). At a 1% edge and a 50% win chance, that is 99 ÷ 50 = 1.98×. A stake of 10 returns 19.80 on a win, not 20.
| Win chance | Multiplier at a 1% edge |
|---|---|
| 90% | 1.10× |
| 75% | 1.32× |
| 50% | 1.98× |
| 25% | 3.96× |
| 10% | 9.90× |
| 1% | 99× |
The gap between 2× and 1.98× is the house edge at work. Sites set their own edge, so check it before you play; the full explanation is in CS:GO dice house edge, RTP and multipliers. We compare what each site publishes in our ranking of the best CS2 dice sites.
Is it luck or skill?
It is luck. The site generates each roll independently, so a previous result tells you nothing about the next one. Staking patterns can change how much your balance swings, but they cannot change the expected loss. After 1,000 wagered at a 1% edge, the expected loss is about 10, and your real result can be far above or below that.
Many sites use a provably fair system so you can check that rolls were not altered after you bet. See how to verify a provably fair dice roll. That proves the roll was fixed in advance, not that you will win.
