Millionaire Craps

Game Mechanics & Rules

Millionaire Craps implements standard two-dice casino craps. The game runs through a Come Out roll and, if a point is established, a Point phase. Each of the two dice resolves from its own SHA-256 hash, so every face is exactly equally likely. How Millionaire Mode's jackpot trigger works for Craps is shown in the in-game Millionaire Mode panel.

1. Place your primary bet on the Pass Line (win on 7 or 11, lose on 2, 3, or 12 on Come Out) or Don't Pass (lose on 7 or 11, win on 2 or 3, push on 12 on Come Out).
2. The Come Out roll is made. A result of 7 or 11 wins Pass Line immediately; 2, 3, or 12 (craps) loses Pass Line immediately. Any other result (4, 5, 6, 8, 9, 10) establishes the Point.
3. Once the Point is established, the objective changes: a Pass Line bet wins if the Point number is rolled again before a 7; it loses if a 7 appears first (a seven-out).
4. Come and Don't Come bets can be placed after the Point is established and operate identically to Pass/Don't Pass but use the next roll as their own Come Out.
5. Field bets are single-roll wagers: win on 2 or 12 (both pay 2:1), or 3, 4, 9, 10, 11 (pay 1:1); lose on 5, 6, 7, or 8.
6. How Millionaire Mode's jackpot trigger works for Craps is shown in the in-game Millionaire Mode panel. Complete all six Precision Challenge stages to win $1,000,000; further rolls do not add chances.

Optimal Strategy & Analysis

These represent the lowest house edges available in the game.

Come and Don't Come bets are structurally identical to Pass/Don't Pass but applied mid-game after Point establishment. This does not reduce aggregate house edge but does increase variance and action density per roll.

The full centre-table menu is available too: hardways (the hard 6 and hard 8 pay 9:1, the hard 4 and hard 10 pay 7:1), the horn, any-craps, big 6 and big 8, and the one-roll field. These sit on top of a Pass or Come core for single-number and one-roll action.

Millionaire Mode trims winning returns by 10%; pushes return your stake in full. That margin funds the jackpot shot: a winning Pass Line bet returns 1.8x your stake instead of 2x, and a Field 2 or 12 returns 2.7x instead of 3x.

Provably Fair Verification

Each Millionaire Craps die has its own hash: SHA-256(server_seed + ':' + client_seed + ':' + nonce + ':' + roll_index + ':' + die_index), where roll_index is 0 for the opening roll and uses the recorded roll position for each further roll of that game, and die_index is 0 for the first die and 1 for the second. The NONCE does not move between those rolls - it identifies the game, and the roll index identifies the roll within it. The first eight hex characters of each hash are read as a 32-bit integer; a value of 4,294,967,292 or above (the top four values, which would make low faces very slightly more likely) is rejected and the die is re-hashed with ':r1', ':r2' and so on appended, and the first value below that line is taken modulo 6 and offset to [1, 6]. Every face is therefore exactly equally likely, and every roll of a session is reconstructable in order. Rounds played before the September 2026 change used the earlier method (characters 0 to 3 and 4 to 7 of one hash per roll, modulo 6), and the fairness page still verifies them under it.

The server seed is committed as its SHA-256 hash prior to session start. Post-session seed revelation allows full reconstruction of every dice result in sequence. Because Point phase rolls may number in the dozens during a single game, use the game nonce and recorded roll positions to identify specific rolls within a session. How Millionaire Mode's jackpot trigger works for Craps is shown in the in-game Millionaire Mode panel. Both dice and trigger are fixed by the same seed commitment made before the round and neither can be steered afterwards.

Players can reveal their server seed and verify recorded rounds in the in-game fairness panel. The committed hash, revealed server seed, client seed, game nonce, and recorded roll positions allow independent reconstruction of the dice outcomes after the session ends.

Millionaire Mode Technical Details

Millionaire Mode in Craps is free to enable; there is no separate per-round fee. Each round can trigger a Golden Roll; the in-game Millionaire Mode panel introduces the bonus for Craps.

While Millionaire Mode is active, standard wins pay at 90% of the off-mode rate. That 10% margin is what funds the jackpot shot on every round; a triggered Golden Roll follows its own jackpot rules.

A Golden Roll opens the jackpot condition. The jackpot is a fixed $1,000,000, pre-funded and paid as a single transaction when the condition resolves.

The jackpot does not accumulate between rounds. Every Golden Roll is a full attempt at the headline figure.
