Two Prime Product Mines: Guide Terms and Demo Rules

Demo Identity and Virtual Currency

This demo is a browser-based simulation provided by this guide. It is not a verified app or an external casino platform. The virtual coins used here have no real-world cash value and cannot be withdrawn or exchanged. The demo asks for no account or payment details. It stores the local wallet and the page makes external resource requests.

• Storage: Your balance and fractional carry are stored in browser localStorage.
• Privacy: The page loads Google Fonts stylesheets and font files, and a Statinside counter script (counter 44). These requests can expose ordinary connection information to the services. Local wallet storage and the absence of a login do not establish anonymity or a complete account of server-side processing.
• Audience: This guide targets an 18+ audience, though no age gate is enforced in the demo.

Wallet, Balance and Restoration

The demo wallet starts with a balance of 1000 play coins. The balance is saved locally, including the stake deduction as soon as a round starts. If you reload during an active round, the round ends without refund or continuation.

Manual Balance Restoration

You can manually restore your balance to exactly 1000 coins when the wallet is idle and the balance falls below 10 coins. This action sets the balance to 1000; it does not add coins to a higher balance. Fractional carry persists across settlement, refill, and reload.

Unfinished Reload Policy

If you reload the page while a round is active (before collecting or auto-banking), the round ends immediately. Your captured stake remains deducted, and there is no refund, payout, or resume option. Controls reset to default stake (20) and the first preset.

Game Mechanics: Two Prime Product Mines

The game uses a 4×4 board with printed labels 1–16 in row-major order. You select 3, 4, or 5 hazards. Hazards are uniformly sampled from complete subsets where the product of selected labels has exactly two distinct prime factors. Safe observations filter this support.

Scoring and Probability

The initial quoted value is 97% of the captured stake. Each successful safe reveal divides the current gross value by the exact posterior safe probability. A cell whose exact conditional safe probability is 1 leaves the gross value unchanged, regardless of how many cells remain. You may collect after at least one safe reveal, or continue with an eligible cell.

Stopping Rules

Choices are disabled when the gross return exceeds 1000× the stake; equality is allowed. The game banks automatically only when no eligible uncertain choice remains.

Payouts and Settlement

A round settles when you collect, the game banks automatically, or you hit a hazard. A hazard returns zero. The floor of the raw gross return plus stored fractional carry is credited. Any remainder persists in the fractional carry. Zero-return rounds leave fractional carry unchanged. The exact expected RTP is 97% across all modes, though measured returns vary by sample.

Controls and Modes

Stakes are selectable as 10, 20, 50, or 100 play coins (default 20). Settings, restoration, and starting a new round are locked while a round is active. Hazard selection (3, 4, or 5) must be made before the round begins.

Scope and Limits

These explanations apply to this guide and its original virtual-coin demo. They do not supply the terms, governing law, licence, payment conditions, or account rules of an outside T44 service.

Play coins have no cash value. The mathematical return is a long-run gross expectation, not a promised result, profit, or guarantee for an individual round. Read the mechanics page for the exact conditional pricing and stopping rules.
