📌 Key Facts
- The wheel: 15 slots. Red 1–7 and black 8–14 pay 2×, green 0 pays 14×.
- The edge is the same on every colour: each bet returns 14/15 of the stake on average, a 6.67% house edge.
- That is about 2.5 times European roulette, where the edge is 2.70%.
- Green is not a better bet, only a more volatile one. The chance of missing green 30 spins in a row is about 12.6%.
- Martingale does not beat it. From 1,000 coins at a 10-coin start, six red losses in a row (about a 2.3% chance) wipe out the ladder.
- Predictors and scripts are scams. Provably fair rolls are fixed by a secret seed before you bet.
- This simulator uses demo coins only. Nothing here can be deposited, won or withdrawn.
How the CS2 colour wheel works
The colour wheel is the game most people mean when they say CSGO roulette. A round lasts a few seconds, everyone bets on a colour, and a strip of numbered tiles scrolls to a stop under a marker. The classic layout has 15 tiles: seven red, seven black and one green zero. The simulator above uses exactly that layout, so the numbers you see here are the numbers you would face on a site that runs the classic wheel.
Not every site copies the classic layout. Some add extra bet types, change the green payout or run a different number of slots, so check each site's own payout table before comparing. Our CS2 roulette sites comparison notes the wheel rules for every site we tested.
Odds, payouts and house edge
| Bet | Slots | Win chance | Pays | Return per coin | House edge |
|---|---|---|---|---|---|
| Red | 1–7 | 7/15 = 46.67% | 2× | 0.9333 | 6.67% |
| Black | 8–14 | 7/15 = 46.67% | 2× | 0.9333 | 6.67% |
| Green | 0 | 1/15 = 6.67% | 14× | 0.9333 | 6.67% |
The arithmetic is short. A red bet wins 7 times in 15 and pays back twice the stake, so the average return is 7/15 × 2 = 14/15, about 0.933 coins per coin. Green wins once in 15 and pays 14 times the stake, which is also 14/15. Whatever colour you pick, you keep 93.3% of what you wager on average and lose 6.67%. The full derivation, and how the wheel compares with crash and dice, is in CS2 roulette house edge explained.
That is the number the red line on the chart tracks. Your yellow line will wander above and below it, sometimes far above for a while. Over enough spins it drifts back toward the red line, because the red line is the only part of the game that is not random.
Why green feels better than it is
Green pays 14×, so a single hit covers a lot of losing spins, and that is exactly the problem. Green appears once every 15 spins on average, but the gaps are uneven. The chance of green not appearing for 30 spins in a row is (14/15)30, about 12.6%. People who raise their green bet after each miss to "catch up" are building a martingale with a much longer losing streak than red ever produces.
The martingale test
The best-known system is to double the bet after every loss so that the next win recovers everything plus the first stake. Try it above: start at 10 on red and double after each loss.
- With 1,000 coins you can afford six bets in a row: 10, 20, 40, 80, 160 and 320, which adds up to 630. The seventh bet would be 640 and you only have 370 left.
- A red bet loses 8 times in 15. Losing six in a row has a probability of (8/15)6, about 2.3%.
- That sounds rare, but each successful cycle only wins 10 coins. Over 100 cycles the chance of hitting the six-loss streak at least once is about 90%, and that single streak costs 630 coins.
No staking pattern changes the 6.67% edge. It only changes the shape of the losses: many small wins and one large loss instead of an even drift.
Roulette predictors, scripts and "hacks"
Searches for CSGO roulette predictors and scripts are common, and every one of those tools is a scam. On a provably fair site the result of a round is decided by a secret server seed before you place a bet. You only see its SHA-256 hash, which lets you check afterwards that the seed was not changed, but tells you nothing about the result in advance. Predicting the roll would mean reversing SHA-256.
Tools sold as predictors usually ask you to log in with Steam, install an extension or enter an API key, which is how Steam accounts and inventories get stolen. More on spotting that pattern: how to spot CS2 gambling scams.
How this simulator decides each roll
Every roll above is provably fair in the same way real sites describe their games, so you can practise the check before you need it:
- Before the spin, the simulator shows the SHA-256 hash of a new random server seed.
- The roll is computed as HMAC-SHA256 with the server seed as the key and
clientSeed:nonceas the message. The first 8 hex characters become a number, and the remainder after dividing by 15 is the tile. - After the spin, the server seed is revealed. Hash it yourself and confirm it matches what was shown before.
- Paste the seed, client seed and nonce into the verifier, or into any public HMAC-SHA256 tool, and you will get the same tile.
You can change the client seed at any time, which is the part that stops a site from choosing a seed that suits it. The same four steps, with the standards behind them, are in how provably fair works.

Frequently asked questions
What are the odds in CSGO roulette?
On the classic 15-slot colour wheel, red covers 7 slots, black covers 7 slots and green covers 1. Red and black each hit 7 times in 15, or 46.67%, and pay 2x. Green hits 1 time in 15, or 6.67%, and pays 14x. Every bet returns 14/15 of the stake on average, so the house edge is 6.67% on all three colours. Some sites use different layouts or payouts, so check each site's own table before comparing.
Is betting on green better than red or black?
No. Green pays 14x on a 1 in 15 chance and red pays 2x on a 7 in 15 chance, and both return exactly 14/15 of the stake on average. Green only changes the variance: you win less often and by more. The chance of missing green 30 times in a row is about 12.6%, which is why chasing green empties a balance faster than people expect.
Does the martingale strategy work on CSGO roulette?
No. Doubling after every loss wins a small amount most of the time and loses everything occasionally. Starting at 10 coins with a 1,000 coin balance, you can afford six bets in a row (10, 20, 40, 80, 160, 320). The chance of losing six red bets in a row is about 2.3%, so across 100 cycles the chance of hitting that streak at least once is about 90%. Each successful cycle wins 10 coins; the losing streak costs 630. The house edge is unchanged by any staking pattern.
Do CSGO roulette predictors or scripts work?
No. On a provably fair site the result is fixed by a secret server seed before you bet, and only its SHA-256 hash is shown. Predicting the roll would require reversing SHA-256 or knowing the seed, which is not possible for a third party. Tools sold as roulette predictors, scripts or jackpot hacks are scams, commonly designed to steal Steam accounts or payment details.
How do I verify a roll in this simulator?
Before each spin the simulator shows the SHA-256 hash of the server seed. After the spin it reveals the seed. Check that the SHA-256 of the revealed seed matches the hash you saw before, then compute HMAC-SHA256 with the server seed as the key and clientSeed:nonce as the message, take the first 8 hex characters as a number and divide by 15; the remainder is the roll. The verifier on this page does exactly that, and any public HMAC tool gives the same answer.
Can I win real money or skins in this simulator?
No. The simulator uses demo coins with no value. Nothing can be deposited, withdrawn or exchanged, and there is no account or login. It exists to show how the wheel, the payouts and the house edge behave over many spins before anyone risks real money.
Is CSGO roulette the same as casino roulette?
No. European casino roulette has 37 pockets and a 2.70% house edge. The classic CSGO colour wheel has 15 slots and a 6.67% edge, roughly two and a half times as expensive per bet. That difference is the main reason the colour wheel empties a balance faster than table roulette at the same stake.
Where can I play CSGO roulette for real?
Our comparison of CS2 roulette sites ranks the platforms we tested on payout speed, bonus terms and wheel rules. Real-money roulette is 18+ only and legal status depends on where you live. Code BINROLL applies on the roulette sites we list except Gamdom, which uses BINBONUS.
