This guide covers the House Games version, currently in beta. Open House Games and check the game name and provider when comparing rules.
The table and objective
House Blackjack supports one to seven seats. Each selected seat uses the same opening main stake and optional side-bet stakes. The main game compares your completed hand with the dealer's, with a total above 21 losing.
Cards are drawn independently from a full 52-card deck, equivalent to an infinite shoe. Cards are not depleted as the round progresses.
Main rules
The dealer stands on all 17s, including soft 17.
The dealer checks for blackjack when showing a ten-value card or an ace. With an ace, the check follows the insurance decision.
A natural blackjack pays 3:2 profit; an ordinary winning hand pays 1:1 profit. Matching naturals push.
A push returns the relevant stake. A losing hand returns nothing for that hand.
Main hand result | Total returned on a $10 stake | Net result |
Natural blackjack wins | $25 | +$15 |
Ordinary win | $20 | +$10 |
Push | $10 | $0 |
Loss | $0 | −$10 |
Double, split and insurance
Double: available on an open two-card hand below 21, including after a split except split aces. It adds another stake equal to the hand's current stake, draws one card and ends that hand.
Split: one split per original seat is allowed for matching ranks or any two ten-value cards. It adds a matching stake and creates two hands. Split aces receive one additional card each. A split-hand 21 is an ordinary 21, not a natural blackjack. A win pays 1:1; a tie pushes.
Insurance: offered against a dealer ace. One decision applies across the selected seats and costs half the initial main stake per seat, subject to rounding. If the dealer has blackjack, insurance pays 2:1 profit, returning three times its stake in total; otherwise it loses.
Main-game return
The theoretical main-game RTP is approximately 99.43% with best play, equivalent to about a 0.57% house edge per initial main stake for these rules. Your decisions affect the return. This figure is not a guarantee for a round or session and does not describe the side bets or cash-out choices.
Perfect Pairs
This optional side bet uses the seat's two opening cards. The paytable below shows profit odds; a winning payout also returns the side-bet stake.
Result | Profit odds |
Perfect pair: same rank and suit | 25:1 |
Coloured pair: same rank and colour, different suits | 10:1 |
Mixed pair: same rank, one red and one black | 6:1 |
The theoretical RTP for Perfect Pairs is approximately 98.08%.
21+3
This optional side bet uses the seat's two opening cards and the dealer's up card. Winning payouts also return the side-bet stake.
Result | Profit odds |
Suited three of a kind | 100:1 |
Straight flush | 50:1 |
Three of a kind | 30:1 |
Straight | 10:1 |
Flush | 4:1 |
The theoretical RTP for 21+3 is approximately 95.22%. An ace can be low in A–2–3 or high in Q–K–A; K–A–2 is not a straight.
How cash out works
When available, Cash out ends the active hand for 90% of its calculated fair expected return under best play. It is not a refund of 90% of the original stake. The offered amount depends on the hand and dealer information and is rounded down. Check the actual offer before accepting it.
Bet limits and total round cost
Use the current limits for your selected wallet currency. Limits apply to the opening main stake per seat, enabled side bets, combined side stakes per seat and maximum potential net profit across the whole round.
Opening cost = number of seats × (main stake + Perfect Pairs stake + 21+3 stake). For example, two seats with a 10 USDT main stake and 1 USDT on each side bet cost 24 USDT before any later double, split or insurance.
Double, split and insurance can increase your total stake. Passing an individual stake limit does not guarantee a round is allowed: multiple seats and side-bet payouts can make the total potential profit too high. A deal or additional paid action that would exceed the profit limit is rejected before that charge is made.
Maximum win means net profit for the whole round: total payout minus all stakes committed. It is not the same as the total returned payout. The opening main-bet limit is also not a cap on all money committed after splitting or doubling.
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.
