About this guide and original demo

The queried name and this guide

Qq22 is the name discussed by this independent guide. An outside operator, affiliation, licence, official address, verified app and customer reviews have not been established here. Search position and similar names cannot establish those facts. The original demo belongs to this guide and does not certify an outside product.

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.

Expected return and a worked example

With 3 hazards there are 170 initial layouts. Label 4 is safe in 132 of them, so its initial safe probability is 132/170, about 77.6471%. At stake 20 the initial gross value is 19.4; safely opening that cell changes it to 19.4 ÷ (132/170), about 24.984848. The checked policies choose eligible uncertain cells as follows: low-1 uses the lowest safe probability and collects after one safe reveal; high-2 uses the highest safe probability and collects after two; first-4 uses the lowest eligible label and collects after four. Probability ties use the lowest label, and automatic collection can end a path earlier. These policies have expected raw gross return of 97% of stake in each hazard mode. This is an expectation over complete outcomes, not a session promise. Sample simulations support the calculation but do not define it. Abandoning a round without settlement is outside that return statement.

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.

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.

Adult audience and personal limits

This guide and demo are intended for adults aged 18 and over. That is an audience choice, not an implemented age gate or a determination of local law. You may set a personal time or virtual-coin limit and take a break between rounds. These limits are voluntary and are not enforced by the interface. There is no timer, account-level self-exclusion or pause-and-resume tool. Closing an unfinished round does not preserve it. If play is difficult to control, appropriate qualified local help may be useful.
