About This Independent Demo Guide

Anti Diagonal One Equality is played on a four-by-four Mines board. The board is drawn uniformly from all boards with the selected mine count satisfying a specific public support rule: among the three neighbouring pairs along the anti-diagonal, exactly one pair has equal occupancy bits.

Support and Drawing The chosen mine count and public constraint define an exact finite board support. Draws are uniform over that support, not over all unconstrained boards. Each safe reveal filters the support.

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 Known-certain mines are disabled. Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed 1000 times the stake are also disabled.

Stopping and Auto-Banking A mine ends the round with zero gross. Manual bank becomes available only after at least one safe reveal. The round ends if you bank, all safe cells are revealed, or no eligible cell remains. When no eligible cell remains, the current quote is automatically banked. A cap guard disables individual above-1000x transitions before a reveal.

The exact gross RTP is 0.96 across all modes. Simulation measurements are supporting sample observations, not the mathematical payout law or a promised return. Expected RTP is not a promised session result.

Initial Balance The initial balance is 1000 virtual coins.

Refill Mechanism A manual refill while idle below 10 sets the integer wallet to exactly 1000. This is a manual idle-only restoration that SETS the balance; it is not adding coins or automatic replenishment. Fractional carry persists across settlement, refill and reload.

Persistence Rules Settled balance persists locally including zero. An unfinished round ends on reload without refund or resume. Captured stake and mine count do not change during an active round. No refill occurs during an active round.

Storage Source uses browser localStorage for settled demo balance and fractional carry. This does not establish anonymity or exclude other processing. Clearing cached files may leave local storage where that storage is actually used.

Third Parties The template declares a Google Fonts stylesheet. Actual browser request capture is pending; this is not a claim that other requests or processing are absent.

Identity The absence of account or payment controls in the demo does not prove that no personal data are processed. Do not promise anonymity, no sale, no profiling, no marketing, encryption guarantees, cookie duration or server retention.

Audience 18+ is this guide's own intended audience where the contract states it; it is not a universal legal age, an implemented age gate, or a statement of local legality.

Responsible Gaming Responsible-use pages can describe optional pauses, a personal time/virtual-coin limit and finding appropriate local qualified help. Do not invent laws, regulators, clinic names, hotlines, opening hours, diagnostic thresholds, clinical research or biological explanations. Do not claim the demo clinically trains behaviour or makes losses safe. Do not promise account-level blocking, a timer or self-exclusion tools that the interface does not have.

This guide covers the following sibling pages: About, FAQ, Home, How Mines Works, Login, Mobile App, Privacy, Real or Fake, Responsible Gaming, and Terms.

Terms explain this guide's own scope; they do not invent legal releases or establish an outside company's policies. A page about payments explains this demo's virtual wallet and the limit of external evidence; a page about login explains that this demo has no account-login flow; an app page describes the browser demo and unverified package identity.
