Anti Diagonal Alternation Demo Review

The game uses a four-by-four board where the initial board is drawn uniformly from all boards with the selected mine count that satisfy the exact public support rule: the anti-diagonal occupancy alternates at each step. This constraint defines a specific, finite board support for each mine count, rather than drawing from all unconstrained boards.

After any safe path, the board support filters further. Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed 1000 times the stake are also disabled. Known-certain mines are disabled. The round ends when a mine is revealed (returning zero), when the player manually banks, or when no eligible reveal remains (auto-banking the current quote).

The payout is calculated using a specific gross quote formula rather than standard Mines multipliers. The exact score function is:

• Gross Quote = 0.96 × captured stake × initial support count / current compatible support count

The initial support count is the number of valid boards at the start of the round for the chosen mine count. The current compatible support count is the number of valid boards remaining after the specific sequence of safe reveals.

A public cap limits individual transitions: any safe reveal that would exceed a 1000-times-stake cap is disabled. When no eligible cell remains, the current quote is automatically banked.

The exact gross RTP for all modes is 0.96 (96%). Simulation measurements support this but are not the mathematical law. Below are exact expected values and measured estimates from the source-bound contract.

This demo uses a virtual wallet. The initial balance is 1000. Fractional carry persists across settlement, refill, and reload.

• Manual Refill: Eligible while idle. If the balance is below 10, a manual refill sets the integer wallet to exactly 1000. This is not an automatic replenishment or a deposit.
• Unfinished Round: If the page reloads during an active round, the round ends without refund or resume.
• Persistence: Settled balance persists locally, including zero balances.

The demo offers a four-by-four board. Mine count choices are restricted to the exact nonempty support configurations in the source. Captured stake and mine count are locked throughout the round.

• Banking: Manual bank becomes available only after at least one safe reveal. No auto queue exists.
• Controls: Stake, mine count, and refill are locked while the round is active. Eligible reveal cells and bank remain available. Sound remains available.

The source uses browser localStorage for settled demo balance and fractional carry. This does not establish anonymity or exclude other processing. The template declares a Google Fonts stylesheet; actual browser request capture is pending, and this is not a claim that other requests or processing are absent.

This demo has no account-login flow or payment flow. Virtual coins have no cash value. Clearing cached files may leave local storage where that storage is actually used.
