Roulette is most direct when betting on a single number. Other standard bets carry no higher payouts or better chances of winning. When a straight-up bet hits, players will receive a 35-to-1 return, and this is the basis for constructing a house edge on every single zero wheel.
A player staking 1,000 satoshis on a single number at https://crypto.games/ and winning collects 36,000 satoshis in total: 35,000 satoshis in profit plus the original 1,000 satoshi stake returned. Which number the chip sits on is irrelevant to the calculation. Number 1 pays the same as number 36. No position on the wheel carries a more favourable straight-up return than any other.
How is the 35-to-1 payout calculated?
Roulette payouts follow a single formula applied consistently across every bet type. Take the pockets not covered, divide by the pockets covered, and subtract one. On a 37-pocket single zero wheel, one number covered leaves 36 uncovered. Divide 36 by 1, subtract nothing, and the result is 36. Subtract one to account for the stake being returned rather than added as profit, and the payout is 35 to 1.
Extending this to other bet types shows the same formula at work. A split covering two numbers: 35 non-covered pockets divided by 2, minus one, gives 17 to 1. A corner covering four: 33 divided by 4 rounds to 8 to 1. Every position on the table uses the same derivation. Straight-up bets sit at the top of that scale because they cover the fewest pockets, producing the highest ratio in the numerator before the subtraction.
What are the real odds behind the payout?
Payout of 35 to 1 implies a win probability of 1 in 36, which is approximately 2.78 per cent. Actual win probability on a 37-pocket wheel is 1 in 37, approximately 2.70 per cent. That gap, small as it looks written side by side, is the entire mechanism through which the house retains an edge on every straight-up chip placed.
Over 37 spins at one unit per spin, the player expects to win once and collect 36 units: the 35-unit profit plus the stake. Total spent across those 37 spins is 37 units. One unit disappears into the house’s margin. Expressed as a percentage of stakes wagered, that is 2.70 per cent. No run of wins changes this ratio when measured across a sufficient volume of spins, because the formula producing the 2.70 per cent gap is structural, not statistical.
Double-zero wheels demonstrate the same relationship at an amplified level. Adding one more pocket changes the true win probability from 1 in 37 to 1 in 38, approximately 2.63 per cent. Payout stays at 35 to 1, still implying 1 in 36. Now the gap between true probability and implied payout is wider, and the house edge climbs from 2.70 per cent to 5.26 per cent. Payout formula unchanged. Pocket count changed. Edge changed accordingly.
Session patterns on straight-up bets
Winning once in every 37 spins on average sounds achievable, but averages flatten out considerable variation. Long sequences without a hit are common and carry no predictive weight for the spins that follow. A chosen number missing for 80 consecutive spins does not become more likely to appear on spin 81. Each spin is independent, and the wheel carries no memory of prior outcomes.
Players covering several different numbers with separate straight-up chips during the same spin increase the number of pockets active per round without changing the per-chip edge. Four chips on four different numbers means four 2.70 per cent edge exposures per spin. Each chip’s probability and payout are calculated individually, and a hit on any of the four numbers pays 35 to 1 on that chip while the other three are removed.
