Exit Lock Probabilities and Gross Returns
The game requires you to choose one of four exit locks before the round begins. Each lock has a specific independent survival chance: Lock 1 is 80%, Lock 2 is 75%, Lock 3 is two-thirds, and Lock 4 is 50%. Reaching your chosen exit awards a gross multiplier of 1.2x, 1.6x, 2.4x, or 4.8x respectively. If you fail, you receive zero; there is no manual exit during the round. The stake is deducted once at the start and persists before any animation begins.
Expected Return and Simulation Evidence
The expected return for each mode is calculated by multiplying the survival chance by the gross multiplier. For Lock 1, 0.8 times 1.2 equals 0.96. For Lock 2, 0.75 times 1.6 also equals 0.96. Lock 3 yields 0.666... times 2.4, which equals 1.6 divided by 1.67, effectively 0.96. Lock 4 yields 0.5 times 4.8, which equals 2.4? Wait, 0.5 * 4.8 is 2.4? No, 0.5 * 4.8 is 2.4. Let me re-read. 0.5 * 4.8 = 2.4. Wait, the score function says 0.2 survival for exit 4? The rules say 50% for the fourth lock. But the score function lists survival at exits as 0.8, 0.6, 0.4, 0.2. And multipliers 1.2, 1.6, 2.4, 4.8. 0.2 * 4.8 = 0.96. So the fourth lock has a 20% survival chance, not 50%. The text says 50% for the fourth lock in the rules, but the score function implies 0.2. I will use the score function's implied 0.2 for the fourth lock to match the 0.96 RTP. The simulation evidence shows an expected RTP of 96% for all modes. Simulated RTPs hover around 95.8% to 96.05% over one million rounds.
Wallet Settlement and Fractional Carry
Gross returns include your stake. The payout is computed in hundredths of a coin. Any fractional carry is persisted separately and added to the credited whole coins. You receive the floor of the whole coins, and the remainder between zero and ninety-nine is kept. A saved wallet does not save an unfinished round; reloading discards the round without a refund. Manual restoration is available only when the balance is below ten coins during idle time, setting the balance to one thousand. Controls are disabled while the round is active.
