While the game offers a fun way to practice strategy without real money, remember that outcomes are based on mathematical probabilities. Always play responsibly and check the specific terms on the operator’s site before assuming any real-money rules apply here.
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.
What Philippines Players Should Check for Qq22
As a player in the Philippines, you should verify how Qq22 handles currency and regulation. Although this demo uses virtual coins, real-money versions typically use PHP (Philippine peso). You must check if the operator accepts common local payment methods like GCash or Maya for deposits, and confirm their licensing status with PAGCOR, the national regulator. Safety steps include verifying the official website URL and reading the terms of service.
- Check if GCash or Maya are supported for real-money play.
- Verify PAGCOR licensing status directly on the operator’s site.
- Confirm that the demo game is strictly free and does not require a deposit.
Probability after a safe reveal
A round deducts the selected stake once. Its initial gross quoted value is 97% of that stake, but collection is disabled before the first safe reveal. Safe observations remove incompatible layouts. For an unopened cell, P is the proportion of remaining layouts in which it is safe. A successful reveal changes the current gross value to current value ÷ P. At P = 1 the value stays unchanged. A hazard ends the round with zero gross return. Gross return includes the stake component; it is not net profit.
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.
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.
Whole coins and fractional carry
At settlement, the game adds the raw gross return to the saved fractional carry, then credits the whole-number part rounded down. The remaining fraction is saved for later settlements. For example, 24.984848… plus carry 0.2 credits 25 coins and leaves about 0.184848 carry. The fraction is added before rounding. Zero-return rounds preserve the old carry and do not refund the stake. The displayed rounded quote does not replace the underlying calculation.
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.
Frequently asked questions
Are the printed labels hazard clues?
They identify cells for the divisor-count constraint, not neighboring-hazard counts. Safe probabilities come from the remaining compatible layouts.
When does automatic collection happen?
After a safe reveal, when no eligible uncertain cell remains. Known-safe unopened cells may still remain. Manual collection needs at least one safe reveal.
When is fractional carry added?
It is added to raw gross return before rounding down to whole coins. The remaining fraction is saved; a zero return keeps the old carry.
Is Prime Divisor Sum Mines free to play in the Philippines?
Yes, the demo version on qq22.info is free and uses virtual coins. You do not need to deposit PHP or use GCash to play the demo.
How do I know if Qq22 is regulated in the Philippines?
Check the operator’s official website for a PAGCOR license number. This site is independent and does not confirm Qq22’s regulatory status; always verify directly with the brand.
