Using the browser demo

Use the browser, without an app package

This guide supplies a browser demo, not a verified official Qq22 app or APK. Open the guide and its rules in your browser; no app package is needed for this demo. The same board and settlement rules apply on a phone and desktop. A different browser or device has separate local storage and does not transfer the saved wallet. No account synchronisation or account recovery flow is supplied.

Actual controls and stopping rules

Stakes are 10, 20, 50 or 100 play coins; defaults are stake 20 and 3 hazards. During a round, stake, hazard selection and balance restoration are locked, and another round cannot start. Sound and eligible cell choices remain available. The random-choice button selects an eligible cell; it does not guarantee safety. Collection becomes available after one safe reveal. Known hazards and choices with prospective gross value above 1,000 times the captured stake are disabled; equality is allowed. After a safe reveal the game banks automatically when no eligible uncertain cell remains, even if known-safe cells are unopened.

A constrained four-by-four board

Prime Divisor Sum Mines has 16 cells labelled 1 to 16, read across each row. Choose 3, 4 or 5 hazards before starting. For each hazard label, count its positive divisors; only complete layouts whose divisor counts add to a prime number are allowed. A prime is an integer above 1 with exactly two positive divisors. Each allowed layout is equally likely. There are 170 layouts with 3 hazards, 635 with 4 and 1,473 with 5. The labels define this constraint; they are not adjacent-hazard clues.

Local balance and manual restoration

The wallet starts at 1,000 play coins only when no valid saved balance is available. A saved balance, including zero, is reused. While no round is active and the balance is below 10, manual restoration sets it to exactly 1,000; it does not add 1,000 or clear fractional carry. The coins have no cash value and no deposit or withdrawal flow is provided. Restoration is a demo control, not recovery of a lost stake.

Reload ends an unfinished round

Balance and fractional carry are saved in browser localStorage when storage is available. Reloading an unfinished round keeps the captured stake deducted and ends that round without refund, payout or resume. The new page is idle with stake 20 and 3 hazards selected. Stored balance is not a saved round or a cloud account. Browser restrictions or removal of site data can remove local persistence.

Storage, fonts and the visitor counter

The demo stores its balance and fractional carry in browser localStorage. Page typography requests Google Fonts stylesheets and font files. Publication also includes the Statinside visitor counter for account 44, with a script and a noscript image request. The noscript image declares referrer policy unsafe-url, which can send the full referring URL, including its path and query, subject to browser behavior. These stated resources are not an exhaustive network or privacy audit. Account and payment controls are absent; that does not establish anonymity or the absence of personal-data processing.
