Game Mechanics: Row Boundary Equality
The game uses a four-by-four board drawn uniformly from all boards with the selected mine count satisfying the exact public support rule: every row has equal first and last occupancy bits. Draws are uniform over that support, not over all unconstrained boards.
Support and Probability
- The chosen mine count and public constraint define an exact finite board support.
- Each safe reveal filters the support.
- Cells with zero conditional safe probability are disabled.
Payout Formula
After any safe path, the gross cashout is calculated as:
Gross Quote = 0.96 × Captured Stake × Initial Support Size / Current Compatible Support Size
- Captured stake and mine count are locked throughout the round.
- A mine returns zero gross.
Controls and Modes
- Four-by-four board with mine count choices limited to the exact nonempty support configurations.
- Manual bank becomes available only after at least one safe reveal.
- No auto queue; manual idle-only refill is available.
- Sound remains available during the round.
Stopping Rules and Caps
- A mine ends the round with zero gross.
- Manual bank ends the round after a safe reveal.
- All safe cells revealed or no eligible cell remaining ends the round automatically.
- Any safe reveal that would exceed the public 1000-times-stake cap is disabled. The cap guard disables individual above-1000x transitions before a reveal.
Mathematical Evidence and RTP
The exact gross RTP is 0.96 for all modes. Simulation measurements are supporting sample observations and do not represent the mathematical payout law.

Wallet and Refill Rules
The wallet facts come only from the source of this demo. The initial balance is 1000 virtual coins.
Refill Mechanism
- A manual refill while idle and below a balance of 10 sets the integer wallet to exactly 1000.
- This is a manual set, not automatic replenishment or adding coins.
- No refill occurs during an active round.
Persistence and Carry
- Fractional carry persists across settlement, refill, and reload.
- Settled balance persists locally, including zero.
- An unfinished round ending on reload ends without refund or resume.
Data Storage and Privacy
Privacy details are limited to explicitly supplied source-observable facts.
- Storage: The source uses browser localStorage for settled demo balance and fractional carry. This does not establish anonymity or exclude other processing.
- Third Parties: The page declares Google Fonts requests and the production builder includes Statinside visitor counter 44. These observations do not establish anonymity or absence of other processing.
- Account Flow: There is no demo account flow and no demo payment flow.
Audience and Responsibility
18+ is this guide’s intended audience policy, not a universal legal age or an implemented age check. Personal time or virtual-coin limits and breaks are optional decisions. The interface has no timer, account-level blocking or self-exclusion control. These terms describe this guide’s own scope and do not establish an outside company’s policies.

Identity is unknown unless a specific fact is explicitly accompanied by a reviewed primary source. 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.

Frequently asked questions
How is the payout calculated in Row Boundary Equality?
The gross cashout is calculated as 0.96 times the captured stake, multiplied by the initial support size, and divided by the current compatible support size. This applies after any safe reveal. A mine returns zero.
How does the wallet refill work?
A manual refill while idle and below a balance of 10 sets the integer wallet to exactly 1000. Fractional carry persists across settlement, refill, and reload. There is no automatic replenishment.
Does the demo use a login or payment system?
No. The demo has no account-login flow and no payment flow. It uses browser localStorage for balance persistence. Clearing cached files may leave local storage if that storage is actually used.
