Two kinds of roulette on one lobby
Stake offers roulette in two forms that share a name and little else. The first is Roulette in the Stake Originals group: a software wheel run by Stake, priced by Stake, with every spin computed from your seeds. The second is the live-dealer tables streamed from outside studios, where a physical ball decides and the studio's rules apply. Everything on this page that involves seeds, verification or a per-coin limit refers to the Original. Live tables cannot be recomputed by anyone.
What Stake publishes about Originals Roulette
The fairness documentation is specific: "Our Roulette is derived from the European version of the game where the wheel consists of 37 possible different pockets, ranging from 0 to 36." The game page shows an RTP badge of 97.30%, and Stake's house-edge guide repeats it: "the Stake Originals Roulette house edge is 2.70%, equivalent to a 97.30% RTP. The single-zero European Roulette wheel gives it a lower house edge than other variants" (both 1 Nov 2026).
| Item | What Stake states | Where |
|---|---|---|
| Wheel | European, 37 pockets, 0 to 36, one zero | Fairness documentation, "Game events" (1 Nov 2026) |
| RTP / house edge | 97.30% RTP, 2.70% house edge | Game-page RTP badge and house-edge guide (1 Nov 2026) |

| Numbers used per spin | One, from a single HMAC-SHA256 round | Fairness documentation, "Implementation" (1 Nov 2026) |
| Minimum bet | $0.0001 or the equivalent | Help centre, "Crypto: Casino Betting Limits" (12 Nov 2026) |

| Live-dealer and other supplier tables | Minimum bets mostly $0.10 to $0.20; maximums "vary across games" | Help centre, "Third Party Games: Casino Betting Limits" (12 Nov 2026) |
Every bet on the table costs 2.70%
A 97.30% return on a 37-pocket wheel pins the payouts down. A bet covering n pockets must pay 36/n minus 1 to 1, the standard European schedule, and each bet then returns 36/37 of the stake:
| Bet | Pays | Winning pockets | Win chance | Return | Stake that reaches the USDT profit cap |
|---|---|---|---|---|---|
| Straight up (1 number) | 35:1 | 1 in 37 | 2.70% | 97.30% | 71,429 USDT |
| Split (2 numbers) | 17:1 | 2 in 37 | 5.41% | 97.30% | 147,059 USDT |
| Street (3 numbers) | 11:1 | 3 in 37 | 8.11% | 97.30% | 227,273 USDT |
| Corner (4 numbers) | 8:1 | 4 in 37 | 10.81% | 97.30% | 312,500 USDT |
| Six line (6 numbers) | 5:1 | 6 in 37 | 16.22% | 97.30% | 500,000 USDT |
| Dozen or column (12 numbers) | 2:1 | 12 in 37 | 32.43% | 97.30% | 1,250,000 USDT |
| Red/black, odd/even, high/low (18 numbers) | 1:1 | 18 in 37 | 48.65% | 97.30% | 2,500,000 USDT |
Payouts are the standard single-zero schedule implied by the stated 97.30% return. Win chance, return and the last column are our arithmetic; the cap is Stake’s 2,500,000 USDT profit limit per bet on Originals (help centre, 12 Nov 2026).
The 2.70% comes from one source: the zero. Payouts are set as if the wheel had 36 pockets, and it has 37. That is true for a single number and for red alike, so spreading chips across many bets, or combining inside and outside bets, produces a blend of positions that all cost 2.70% of the amount placed. A bet that covers 35 numbers wins almost every spin and loses 35 units on the two it misses; the average is the same 1/37 of the total.
Stake's documentation does not mention la partage or en prison, the rules under which an even-money bet gets half its stake back, or stays for another spin, when zero lands. The stated 97.30% leaves no room for either: with la partage the even-money bets alone would return 98.65%. Treat zero as a full loss on every bet that does not cover it.
What independence looks like in numbers
Each spin draws a fresh number from the hash, so the wheel has no memory. The table gives the chance of some common "it must be due" situations arising by chance alone.
| Spins | A chosen number has not appeared | Red has not appeared | Zero has appeared at least once |
|---|---|---|---|
| 5 | 87.20% | 3.57% | 12.80% |
| 10 | 76.03% | 0.1275% | 23.97% |
| 20 | 57.81% | 0.0002% | 42.19% |
| 37 | 36.29% | Under 0.0001% | 63.71% |
| 100 | 6.46% | Under 0.0001% | 93.54% |
Arithmetic for a 37-pocket wheel: 36/37 per spin for one number to miss, 19/37 for red to miss.
After 37 spins, one full wheel's worth, any given number has still failed to appear more than a third of the time. Ten spins without red happen about once in 784 ten-spin runs. Neither makes the missing outcome more likely on the next spin: its chance is 1 in 37, or 18 in 37, exactly as before. Progressions built on waiting for a result to come due are betting on a memory the generator does not have.
How a spin is derived from your seeds
Roulette is among the Originals Stake lists as needing "only 1 incremental number". The steps:
- HMAC-SHA256 is computed with the server seed as key and
clientSeed:nonce:0as message. - The first four bytes become a number between 0 and 1, by the same byte-over-256 sum used for every Stake Original.
- The number is multiplied by 37 and rounded down. The result, 0 to 36, is the pocket. Stake's index lists the pockets in plain numerical order, so there is no hidden wheel layout in the computation: the on-screen wheel is decoration around a number that already exists.
pocket = POCKETS[ floor(float × 37) ] with POCKETS = [0, 1, 2, …, 36]
Four bytes give 4,294,967,296 equally likely values. That is not a multiple of 37, so seven of the pockets get one more value than the other thirty, a difference of one part in 116 million. No pocket is favoured in any way that could be measured or used.
The server seed is committed by its SHA-256 hash before you bet and revealed when you rotate the seed pair; the client seed is yours to set. To check a spin, hash the revealed server seed and compare it with the commitment, then run the seed, your client seed and the bet's nonce through our Stake seed checker or the Roulette verifier, which print the pocket and the intermediate hash. Because all your chips in one spin share one nonce, a single check covers every bet placed on that spin. Background: what provably fair gambling proves and the general verifier.
Live-dealer tables: different rules, no seeds
Stake's help centre treats supplier games separately from Originals. For them "the minimum bet amount for most third-party games ranges between $0.1 and $0.2", maximum bets "vary across games" and are shown in each game's menu, and maximum profit "can be calculated using information about the max multiplier mentioned in the game rules". The per-coin Originals limits above do not apply.
On a live table the house edge depends on the wheel the studio uses. A single-zero wheel costs the same 2.70% as the Original. A double-zero wheel has 38 pockets with the same payouts and costs 2 in 38, or 5.26%, nearly twice as much. Multiplier variants that pay boosted amounts on random numbers fund those boosts by lowering the straight-up payout. The number of green pockets and the paytable are printed in each table's rules, and they are the two things to read before sitting down. Fairness on these tables rests on the studio's licence and equipment testing, not on a hash you can recompute.
Stake Roulette against Shuffle, Roobet and Gamdom
"Roulette" names three different games across these four casinos.
| Stake | Shuffle | Roobet | Gamdom | |
|---|---|---|---|---|
| Game | 37-pocket European wheel | 37-pocket European wheel | 15-tile colour wheel | 101-number colour wheel |
| Bets | Full inside and outside layout | Full inside and outside layout | Red, black, green, bait | Red, black, green |
| Stated return | 97.30% RTP | 97.30% RTP | None stated | 99% after the first $5,000 of daily Originals wagering |
| Return from the payouts | 36/37 = 97.30% on every bet | 36/37 = 97.30% on every bet | 14/15 = 93.33% on every bet | 100/101 = 99.01% on red or black |
| Rounds | Your own spin, your own seeds | Your own spin, your own seeds | Shared round on a hash chain | Shared round on a hash chain |
| Limits | Per coin; profit cap e.g. 2,500,000 USDT | $30,000 bet, $300,000 win | $100,000 bet, $3,000,000 payout | $600,000 on red or black, $200,000 on green per the help centre |
Shuffle: game page and help centre, 12 Nov 2026. Roobet: help centre, verifier and public game settings, 12 Nov 2026. Gamdom: verifier and help centre, 12 Nov 2026.
Stake and Shuffle run the same wheel with the same formula, floor(float × 37), so our checker reproduces both. Roobet's and Gamdom's games are colour wheels; they are not roulette in the casino sense, and the edge on each is set by how many tiles lose, which is why one is far dearer than Stake's wheel and the other cheaper.
