Game Mechanics: Prefix Ballot Rows
The game uses a four-by-four board drawn uniformly from a specific legal support defined by the prefix constraint. For each prefix length from one to four, the number of mines in the top rows must be greater than or equal to the number of mines in the left columns.
- Support and Draws: The board is drawn uniformly from this exact finite support, not all unconstrained boards. Each safe reveal filters the support further.
- Payout Formula: Gross quote = 0.96 × captured stake × initial support count / current compatible support count.
- Staking and Caps: Captured stake and mine count remain locked during the round. Reveals that would exceed a 1000-times-stake cap are disabled. When no eligible cell remains, the quote is automatically banked.
- Controls: Manual bank is available after the first safe reveal. No auto queue exists. Sound remains available throughout.
The exact eligible mine count configurations are defined by the source support. Cells with zero conditional safe probability are disabled.
Wallet and Refill Rules
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.
Data Storage and Privacy
The source uses browser localStorage for the current demo balance and fractional carry. This indicates local storage but does not establish anonymity or prove that no other personal data is processed.
- Third Parties: The template declares a Google Fonts stylesheet. Actual browser request capture is pending; this is not a claim that other requests are absent. The HTML also declares a Statinside script and a Statinside pixel for browsers without JavaScript; actual requests depend on the browser.
- No Anonymity Guarantee: The absence of account controls in the demo does not prove that no personal data are processed.
Audience and Responsibility
The intended audience for this guide is 18+. This is a policy choice for this independent guide and is not a claim about local law or an implemented age gate. Responsible use pages may describe optional pauses or personal limits, but the demo does not clinically train behavior or make losses safe. It does not offer account-level blocking or self-exclusion tools beyond the local interface.
Mathematical Evidence and RTP
The exact gross RTP is 0.96. Simulation measurements are supporting observations, not the mathematical payout law. The following table presents exact mathematical evidence for various mine counts and policies.

Identity and Scope
This demo belongs to this independent guide and does not certify or reproduce any outside product. The queried name AA555 is used as a neutral identifier. No operator catalogue, affiliation, registration, official link, verified app, licence, bonus, payment method, KYC process, support channel, or financial service is established by the query. A page about payments explains this demo's virtual wallet; a page about login explains that this demo has no account-login flow.
Frequently asked questions
How is the wallet balance restored?
When the integer wallet is below 10 and the user is idle, a manual refill sets the balance to exactly 1000. This preserves any fractional carry. It is not an automatic replenishment or a refill during an active round.
What happens to unfinished rounds on reload?
An unfinished round ends without refund or resume upon reload. The current wallet balance, including the debit for a started round, persists locally, including zero, but the round state does not.
Does the demo store personal data?
The source uses browser localStorage for the current demo balance and fractional carry. This does not establish anonymity or exclude other processing. The absence of account controls does not prove that no personal data are processed.
