This guide covers the House Games version, currently in beta. Open House Games and check the game name and provider when comparing rules.
How a round works
Choose a stake and a winning range. Each round produces a roll from 0.00 to 99.99, in steps of 0.01. The selected range determines your win chance and payout multiplier.
Which results win?
Bet type | Winning result |
Roll Over | At or above the target. A roll equal to the target wins. |
Roll Under | Below the target. A roll equal to the target loses. |
Inside | At or above the lower bound, but below the upper bound. |
Outside | Below the lower bound, or at or above the upper bound. |
For an Inside range of 25.00–75.00, winning rolls run from 25.00 through 74.99. Outside the same range wins below 25.00 or at 75.00 and above.
Win chance, payout and RTP
The permitted win chance ranges from 0.01% to 98%. With the 1% house edge, the payout multiplier is 99 ÷ win chance, where win chance is written as a percentage number. Multipliers are rounded to eight decimal places.
Example: a 49.50% chance gives a 2× multiplier. A winning $10 stake returns $20 in total: the original $10 plus $10 profit. A losing round returns $0.
The nominal theoretical return is 99% RTP. This describes long-run mathematics, not the proportion of a particular deposit or session that will be returned. Outcome precision, multiplier rounding and payout rounding affect the exact result.
The multiplier range runs from approximately 1.01020408× to 9,900×. A higher multiplier has a lower win chance and may require a smaller stake to remain within the profit limit.
Return versus profit
A winning payout is stake × multiplier and includes the stake. Net profit is that payout minus the stake. Payouts are rounded down to eight decimal places.
Minimum bet, maximum bet and maximum win
Your limits depend on the selected wallet currency. Check the minimum stake, maximum stake and maximum win shown for the game. A dollar display is not a replacement for your wallet-currency limits.
The maximum win limit means net profit, excluding your returned stake. A higher multiplier can reduce your maximum allowed stake:
Maximum stake = the lower of the currency's maximum bet and maximum net profit ÷ (multiplier − 1), rounded down to the permitted currency precision.
Illustrative example: if the maximum bet is $5,000 and the maximum net profit is $100,000, the stake ceiling is $5,000 at 2×, but $1,010.10 at 100× for a currency allowing cents. These example amounts are not a promise of the limit for every currency.
A bet that exceeds the limit is rejected before it is accepted. If a high multiplier makes the permitted stake smaller than the minimum bet, that combination cannot be placed.
Checking a result
The game uses a server seed, a client seed and a nonce to generate a round. The server seed is committed to by a hash and revealed after rotation. Verification must use that round's recorded inputs and fairness version.
If a result or wallet credit looks wrong, contact support with the game name, round reference, stake, currency, selected settings and displayed result. Beta feedback can also be shared through live support.
