Terms of Use

39H is the queried name addressed by this guide. An outside operator, company registration, licence or affiliation has not been verified here. This does not prove that an outside entity does not exist. These rules apply to this guide’s own virtual-coin demo.

Choose 3, 4 or 5 mines on a 4×4 board. Empty rows are allowed and may repeat. Only the nonzero four-bit row patterns must be distinct. The legal-board counts are 400, 1,264 and 2,928 respectively. Cryptographic 32-bit rejection sampling gives every board in the selected set equal probability. Safe reveals narrow the compatible boards.

Gross quote = 0.96 × captured stake × initial legal-board count ÷ current compatible-board count. Gross includes the returned stake and is not net profit. Exact expected gross RTP is 96%, not a guaranteed session result. The saved first-cell 3-mine sample measured 95.94% over 1,000,000 rounds; measured percentages are observations, not the exact law.

A mine returns zero gross. Manual banking is available after the first safe reveal. Certain mines and transitions whose safe return would exceed 1,000 times the stake are disabled before reveal. Revealing all safe cells or having no eligible reveal remaining banks the quote automatically.

The initial integer wallet is 1,000 virtual coins. Only while idle with integer balance below 10 does manual refill set that balance to 1,000 while retaining fractional carry. Settlement adds carry to the gross return, credits its whole-number portion and saves the remainder. Balance and carry persist in this browser, including zero balance. Reloading an unfinished round keeps its stake deducted without refund, return or resume.

The wallet balance and fractional carry use browser localStorage. This does not guarantee anonymity or describe all processing. Google Fonts is declared in the template, and the production builder declares Statinside visitor analytics counter 44. Actual browser capture is pending; neither declaration establishes retention or the contents of every request. Clearing cached files alone need not delete localStorage. Remove this site’s stored data through your browser settings if you want to clear it.

The 18+ label is this guide’s audience policy, not an implemented age gate or a statement of local legality. You may choose breaks or personal limits outside the interface. The demo has no pause button, enforced timer, coin-limit setting or self-exclusion control. Its payout cap and refill do not guarantee safe behaviour. Closing the page ends your interaction; reloading an active round leaves its stake deducted without refund or resume. Clearing local data is not self-exclusion.

Simulation measurements support but do not define the mathematical law. Exact RTP is 0.96 gross. No external payments, KYC, or support channels are part of this demo. Terms here apply only to this guide’s content and demo.
