The intended audience for this guide is 18+. This is a policy for this guide, not a statement of local law or an implemented age gate.

Understanding the Demo Wallet

The demo uses a virtual wallet that is independent of any external banking system.

  • Initial Balance: The wallet starts at 1000 virtual coins.
  • Manual Refill: If the balance is below 10 while idle, a manual refill sets the balance to exactly 1000. This is a manual action, not automatic replenishment.
  • Fractional Carry: Fractional values persist across settlement, refill, and reload.
  • Persistence: Settled balances persist locally. An unfinished round ending on reload does not refund or resume.

Privacy and Data Storage

Privacy in the demo is limited to what is observable in the source code.

  • Local Storage: The source uses browser localStorage for the settled demo balance and fractional carry. Clearing cached files may leave local storage.
  • No Account: There is no demo account flow. The absence of account controls does not prove that no personal data are processed.
  • 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.

The absence of specific data controls does not imply anonymity, no profiling, or no marketing.

Responsible Use Tools

You may take a break by stopping cell reveals and choose personal time or virtual-coin limits. These are decisions you make, not built-in limit or pause tools. After a safe reveal you can bank the current quote and finish the round. Reloading an unfinished round loses its captured stake without refund or resume. There is no automatic queue, timer, account-level block or self-exclusion control. Seek appropriate local qualified support if play concerns you.

Game Mechanics and Volatility

The Row Boundary Equality game uses a four-by-four board with specific constraints.

  • Support: Boards are drawn uniformly from those where every row has equal first and last occupancy bits.
  • Payout: Gross quote = 0.96 × captured stake × initial support / current compatible support.
  • Cap: Reveals exceeding a 1000× stake cap are disabled.

Expected RTP is not a promised session result. Simulation measurements are supporting observations, not the mathematical payout law.

Wallet Facts and Refill Logic

Wallet facts come only from the source of this demo.

  • Refill Threshold: Manual refill is eligible only when idle and balance is below 10.
  • Settlement: Captured stake and mine count do not change during a round. No refill occurs during an active round.
  • Reload: Unfinished rounds end without refund or resume. Progress is not resumable across reloads unless specifically stated for settled balances.

What This Guide Does Not Claim

This guide does not invent or claim:

  • Specific laws, regulators, or clinic names.
  • Clinical training of behaviour or that losses are safe.
  • Account-level blocking, timers, or self-exclusion tools that the interface does not have.
  • External cashier deposits, KYC processes, or verified app packages.
  • That the demo certifies any outside product.

Frequently asked questions

Is the demo wallet linked to real money?

No. The virtual coins in this demo do not have cash value. There is no payment flow or external banking link.

How do I pause my game?

You can stop revealing cells at any time. There is no automatic play; you must manually choose to reveal or bank.

Does clearing cache delete my balance?

Clearing cached files may leave local storage where the balance is stored. However, if you reload during an unfinished round, it ends without refund or resume.
