Millionaire Tower

Game Mechanics & Rules

Millionaire Tower is a multi-stage provably fair game where the player ascends a tower by selecting safe tiles at each level. Each level presents a row of columns, one or more of which hide mines. A successful selection advances the player to the next level with an increased multiplier; a mine selection ends the round.

1. Select a difficulty: Easy (4 columns, 1 mine), Medium (3 columns, 1 mine), Hard (2 columns, 1 mine), or Expert (3 columns, 2 mines).
2. Set your bet amount.
3. At each level, the tower displays the configured number of columns. Click any column to reveal it.
4. A safe tile advances you to the next level; the multiplier updates according to the difficulty and level reached.
5. A mine tile ends the round immediately; the bet is lost and mine positions for all unreached levels are revealed.
6. At any point between levels, click Cash Out to secure the current multiplier as your payout.

Optimal Strategy & Analysis

Each Tower level presents a hypergeometric selection problem. On Easy difficulty (4 columns, 1 mine), P(safe) = 3/4 = 75% per level. On Expert (3 columns, 2 mines), P(safe) = 1/3 ≈ 33.3%. The multiplier per level is calibrated as 1/P(safe) × 0.98, compounding multiplicatively across levels. After L levels on Expert, the total multiplier is (3/1)^L × 0.98, theoretically reaching hundreds of times the bet at high levels.

The expected value of cashing out at any level equals 0.98 × bet across all difficulty levels and tower heights. However, the variance profile differs significantly: Easy provides slow multiplier growth with high survival probability, while Expert provides fast multiplier growth at the cost of a 66.7% failure probability per level. After just 5 levels on Expert, the probability of survival is (1/3)^5 ≈ 0.4%, while the multiplier exceeds 200x.

From a session management perspective, Expert difficulty requires a large bankroll buffer. The expected number of rounds before survival to level 5 is approximately 1/0.004 = 250 rounds. At a standard bet of $5, reaching level 5 requires an expected $1,250 in bets before one success - though the $1,000+ payout from a 200x level-5 success covers many prior losses. Medium difficulty (1 in 3 mines) offers a practical balance between multiplier growth and survival depth.

The Golden Tower (Millionaire Mode) requires completing Expert difficulty to the final level. The exact number of levels and the completion path are fixed by the jackpot design spec. Players should approach Expert purely for the multiplier growth and jackpot eligibility, not for session EV, which is identical to other difficulty settings.

Provably Fair Verification

Tower tile positions (safe or mine) at each level are determined by a SHA-256-seeded shuffle applied per level. For each tower level L, the hash SHA-256(server_seed + ':' + client_seed + ':' + nonce + ':' + L) determines which column(s) in that level contain mines using a modulo selection from the hash output. Mine positions for all levels are computed atomically from the committed seed before the round starts.

The server seed hash is committed at session start. After client seed rotation, the server seed is revealed, allowing reconstruction of all mine positions across all levels for any historical round. This includes levels the player never reached - the full mine map is verifiable regardless of how deep the run went. WickedBet's fairness documentation specifies the per-level hash derivation for independent verification.

Millionaire Mode uses a separate hash chain for the Golden Tower challenge, with mine positions in the jackpot attempt derived from the '_mm' nonce suffix chain. This ensures the jackpot mine layout cannot be derived from or correlated with the standard game mine layout.

Millionaire Mode Technical Details

Millionaire Mode in Tower is free to enable; there is no separate per-round fee. Each round can trigger a Golden Round; the in-game Millionaire Mode panel shows exactly how the trigger works for Tower.

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; the main-game mechanics are unchanged.

A Golden Round 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 Round is a full attempt at the headline figure.
