House Hold'em
Game Mechanics & Rules
Players post an Ante and optionally an Aces Open side bet. Two hole cards are dealt to the player and dealer, followed by a three-card flop. After seeing the flop, the player either folds (forfeiting the Ante) or calls by placing a Call bet of exactly 2x the Ante. The dealer and player then each play the best five-card hand from their two hole cards plus the shared five-community-card board. The dealer qualifies with a pair of 4s or better.
- Place your Ante bet and optionally the Aces Open side bet. Millionaire Mode is a paid $1 Royal Spades side bet that runs alongside the round; it does not reduce your main House Hold'em payouts. The Aces Open pays based on your two hole cards combined with the three flop cards, regardless of the main game outcome.
- Two hole cards are dealt face-up to you and two face-down to the dealer. A three-card flop is dealt face-up and shared between both hands.
- Evaluate your five-card hand potential (your two hole cards plus the three flop cards) and decide: fold to forfeit your Ante, or call by placing a Call bet of 2x your Ante.
- If you call, the turn and river community cards are dealt, completing the five-card board. Both player and dealer use all five community cards plus their respective two hole cards.
- The dealer qualifies with a pair of 4s or better using their best five-card hand. A non-qualifying dealer pays the Ante by the Ante Reward ladder (1:1 for a straight or less, up to 100:1 for a royal flush) and pushes the Call bet.
- With a qualifying dealer, hands are compared using standard Texas Hold'em rankings. Player wins: the Ante pays the Ante Reward ladder (pair to straight: 1:1, flush: 2:1, full house: 3:1, four of a kind: 10:1, straight flush: 20:1, royal flush: 100:1) and the Call bet pays 1:1.
Bets and Payouts
Player and dealer each get 2 hole cards; 3 community cards dealt, then turn/river. Player calls (2x Ante) or folds. Dealer qualifies with a pair of 4s or better. Eight optional side bets cover the AA flop ladder, hole-card structures, the dealer's hole cards, the Three Card Combo three-card hand, and the 5-card community board. Colour Bonus and All Even require a Call; folding forfeits both. Millionaire Mode adds a $1 Royal Spades ticket; main-table payouts are unchanged when MM is on.

Optimal Strategy & Analysis
The optimal fold/call decision in House Hold'em is more complex than single-threshold games due to the flop information available. The general strategy is: a pair on the board does not automatically make calling worthwhile; fold with no pair and no realistic draw to beat the dealer's likely qualifying hand. More specifically, fold only on the weakest holdings - two unsuited, unconnected hole cards below pair that do not have flush or straight draw potential against the specific flop texture. Academic analysis places the fold frequency for optimal strategy at approximately 18% of hands.
The dealer qualification threshold of pair of 4s ensures frequent qualification (approximately 75.78% of dealer hands qualify), meaning Call bet resolution is the norm rather than the exception. The house edge derives primarily from the 2x call requirement and the payout structure rather than qualification mechanics.
The Aces Open side bet pays based on the player's two hole cards plus the three flop cards. Its pay table: pair of aces 7:1, two pair 7:1, three of a kind 7:1, straight 7:1, flush 20:1, full house 30:1, four of a kind 40:1, straight flush 50:1, royal flush 100:1. It is an independent wager with its own pay table and no influence on the main hand.
Millionaire Mode is a paid $1 Royal Spades side bet that runs alongside the round; it does not reduce your main House Hold'em payouts. The check runs on the same dealt cards as the main hand - no separate chain, no spawn cap. The $1 stake is the entire incremental cost; main-table payouts on Ante, Call, and Aces Open are NOT modified.
Provably Fair Verification
House Hold'em hand generation uses SHA-256 Fisher-Yates applied to a 52-card deck using the standard server seed, client seed, and nonce construction. Card deal order is: player hole cards 1-2, dealer hole cards 1-2, flop cards 1-3, turn card, river card - nine cards total per hand. All nine cards are determined before any are displayed. The server seed hash is committed prior to session start. End the fairness session to reveal its server seed, enabling reconstruction of every hand's nine-card sequence.
The Aces Open outcome is determined by the same nine-card sequence - specifically the player's two hole cards and the three flop cards (positions 1-2 and 5-7 in the deal sequence). No additional randomness is introduced for the Aces Open. Millionaire Mode is a paid $1 Royal Spades side bet that runs alongside the round; it does not reduce your main House Hold'em payouts.
Verification of any hand requires: (1) revealed server seed after ending the fairness session, (2) recorded client seed for the hand, (3) hand nonce. Apply Fisher-Yates with SHA-256 using the concatenated seed string to generate the shuffled 52-card deck. Read cards at positions 0-8 in deal order. Compare reconstructed cards against recorded hand. Community card positions 4-8 form the flop/turn/river board used by both player and dealer hands.
Millionaire Mode Technical Details
Millionaire Mode is a paid $1 Royal Spades side bet added to every round. Main-table payouts are NOT reduced. The required main wager must meet the displayed Millionaire Mode minimum.
Each round, the card sample selected for the side bet is checked. The Royal Spades are the six top spades - 9, 10, Jack, Queen, King and Ace of spades. Every distinct Royal Spade in the sample counts as one hit; a repeated rank does not count twice and printed jokers never count.
Paytable per $1 side bet: 6 hits = $1,000,000; 5 hits = $5,000; 4 hits = $325; 3 hits = $20; 2 hits = $2; 0 or 1 hits pay nothing.
The $1,000,000 prize is pre-funded and paid in a single transaction on six hits. Lower tiers pay alongside the round settlement. Royal Spades pays separately whether your main bet wins or loses.

Eight side bets are available: Aces Open, Suited Hole, Connector, Dealer Connector, Pairs Up, Three Card Combo, Colour Bonus, All Even. Each is a separate wager placed before the round and settles under the conditions shown in the side-bet table.
What is House Hold'em and how does it work?
Players and dealer each receive two hole cards and share a five-card community board. After the three-card flop, players choose to fold or call at 2x the Ante. The dealer qualifies with a pair of 4s or better. The Call pays a flat 1:1; the Ante pays the Ante Reward ladder from 1:1 (straight or less) to 100:1 (Royal Flush) whenever it wins. An optional Aces Open side bet pays on player hole cards plus flop. Millionaire Mode is a paid $1 Royal Spades side bet that runs alongside the round; it does not reduce your main House Hold'em payouts.
How does Millionaire Mode function in House Hold'em?
Millionaire Mode is a paid $1 Royal Spades side bet per round. Main-table payouts are NOT reduced. Each round the selected card sample is checked; every distinct Royal Spade - 9, 10, J, Q, K, A of spades - is one hit (printed jokers never count). Paytable: 6 hits = $1,000,000, 5 = $5,000, 4 = $325, 3 = $20, 2 = $2, 0-1 = no payout. The jackpot is pre-funded.
How can I verify House Hold'em is provably fair?
House Hold'em uses SHA-256 Fisher-Yates card generation. Nine cards are determined per hand in order: player hole[1-2], dealer hole[1-2], flop[1-3], turn, river. Server seed is committed as its hash before session start. End the fairness session to reveal its server seed. Verification applies the published algorithm to revealed server seed, client seed, and hand nonce. The Aces Open is verified from the same sequence (positions 1-2 and 5-7). Millionaire Mode is a paid $1 Royal Spades side bet that runs alongside the round; it does not reduce your main House Hold'em payouts.
Which cryptocurrencies are accepted for House Hold'em?
Deposits are made in crypto, and the cashier lists the coins accepted. You play House Hold'em in whichever of your balances you select, and every stake and payout is settled in that currency. Withdrawals return on-chain to a wallet address you nominate at cash-out time, subject to standard network confirmation.
What is the mathematically optimal strategy for House Hold'em?
A pair on the board does not automatically make calling worthwhile. Assess flush potential across all five visible cards. Call with any open-ended straight draw; fold only with two completely unconnected, unsuited hole cards that have no board interaction. Fold frequency under optimal play is approximately 18%. The Aces Open requires no strategic decision. Millionaire Mode is a paid $1 Royal Spades side bet that runs alongside the round; it does not reduce your main House Hold'em payouts.
