The game uses a four-by-four board with a unique support constraint. Payouts are calculated from the initial support size relative to the remaining compatible support. This guide explains the mechanics, wallet behavior, and privacy observations without assuming an external platform.
Game Mechanics & Rules
The board is a four-by-four grid. A board is drawn uniformly from all configurations satisfying a specific prefix constraint: for each prefix length from one to four, the number of mines in the top rows must be at least the number of mines in the left columns. This defines an exact finite support for each mine count.
After any safe reveal, the gross cashout is calculated as 96 percent of the captured stake times the initial support size divided by the current compatible support size. Known-certain mines are disabled. Cells with zero conditional safe probability are also disabled.
If a safe reveal would exceed the public 1000-times-stake cap, that transition is disabled. However, the current quote is automatically banked only when no eligible reveal remains, or when the player manually banks after at least one safe reveal. A mine returns zero and ends the round. Captured stake and mine count remain locked throughout the round.
Controls & Modes
The demo offers a four-by-four board. Mine count choices are limited to the exact nonempty support configurations in the source. Controls are locked while the round is active, except for eligible reveal cells and the bank button (available after a safe reveal). Sound remains available.
There is no auto queue. The player must manually bank or wait for the automatic bank when no eligible cells remain. The demo does not support multiple simultaneous rounds or auto-play queues.
Payout & Settlement
Draws are uniform over the legal board support, not over all unconstrained boards. The gross quote formula is: 0.96 × captured stake × initial support count / current compatible support count.
A mine returns zero gross. The cap guard disables individual transitions exceeding 1000x stake before a reveal. When no eligible cell remains, the current quote is banked automatically. There is no refill during an active round; captured stake and mine count do not change.
Wallet & Persistence
The wallet starts with 1000 virtual coins. Available stakes are 10, 20, 50, 100 and 200; the selected stake is debited and saved when a round starts. Stake and mine count stay fixed during that round.
At settlement, the game credits floor(gross return + previously saved fractional carry), then saves the remaining fraction. A mine returns zero. The carry survives settlement, refill and reload.
When idle with fewer than 10 coins, manual refill sets the integer balance to exactly 1000; it does not add 1000. Reloading abandons an unfinished round without refund or resume. The saved balance includes its already-debited stake. Clearing cached files alone may leave localStorage intact.
Math Evidence & Simulation
Simulation measurements are supporting observations, not the mathematical payout law. The exact gross RTP is 0.96 for all modes. Measured RTP varies slightly due to sample size.
| Mines | Policy | Exact RTP | Measured RTP | Surviving Boards | Gross Multiplier |
|---|---|---|---|---|---|
| 3 | 0 | 0.96 | 96.0246 | 204 | 1.2 |
| 3 | 1 | 0.96 | 96.0418 | 101 | 2.4238 |
| 3 | 5 | 0.96 | 96.1775 | 1 | 244.8 |
| 4 | 0 | 0.96 | 95.9195 | 588 | 1.2931 |
| 4 | 5 | 0.96 | 95.8621 | 1 | 760.32 |
| 5 | 0 | 0.96 | 96.0062 | 1260 | 1.408 |
| 5 | 5 | 0.96 | 95.6972 | 2 | 887.04 |
Fractional carry and gross-versus-net wording follow the actual contract. Expected RTP is not a promised session result.
Privacy & Storage
The source uses browser localStorage for current 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. The HTML also declares a Statinside script and a Statinside pixel for browsers without JavaScript; actual requests depend on the browser.
The absence of account or payment controls in the demo does not prove that no personal data are processed. There is no demo account flow or payment flow. Clearing cached files may leave local storage where it is actually used.
Frequently asked questions
Is AA555 an official operator?
This independent guide has not verified an outside operator, official application or affiliation for the queried name AA555. The browser demonstration here is Prefix Ballot Rows and uses virtual coins.
How does the wallet refill work?
A manual refill while idle and below 10 sets the integer wallet to exactly 1000. It preserves fractional carry. There is no automatic replenishment or refill during an active round.
What happens if I reload the page?
The current wallet balance, including the debit for a started round, persists locally. However, an unfinished round ends without refund or resume. Fractional carry persists across reload.
