Session limits
This demo is restricted to adults 18+ and uses coins without cash value or prizes. Set session time and virtual-coin limits before playing, then stop at those limits. Raising a stake to recover losses does not improve expectation. If playing affects responsibilities or becomes hard to control, stop and seek suitable independently verified local support.
Expected return and variance
Exact expected return is 97% for permitted stopping policies. The initial 3% reduction is applied once; conditional safe-branch compensation preserves expectation. Choosing coordinates or stopping changes risk and variance, not this expectation. A short session is not guaranteed to match it.
Local wallet and refill
Settled balance and fractional payout carry persist in localStorage. Reloading during a round ends it without refunding its already deducted stake. Outside a round, refill restores 1000 coins when balance is below the smallest stake; it does not add 1000 or reset fractional carry. Hazard count, stake and refill are locked during play.
Own-site rules and age restriction
These rules describe only this original virtual game. This guide does not determine legal availability of an external service, certify its fairness or promise income. The own-site 18+ restriction is not a statement about every jurisdiction’s legal age.
Unverified external claims
A matching brand, professional design, search result or HTTPS connection does not verify ownership, authorisation or safety. Match any claim against an independent regulator register, including entity, current status, scope and listed domains. No operator licence or service is endorsed here.

What is the corner constraint?
Choose 3,4 or 5 hazards on a 4×4 board. Exactly one of the four corners A 1,A 4,D 1,D 4 is a hazard; the other hazards occupy the 12 non-corner cells. All 264/880/1980 legal layouts respectively are equally likely and stay fixed during a round.
How is value calculated?
Live value starts at 0.97 times the virtual stake. A safe reveal divides it by that cell’s exact conditional safe probability among the remaining compatible legal layouts. A hazard ends the round with zero return. Reveals change knowledge, not the hidden layout.
What are the initial odds?
With 3 hazards, each corner is initially safe with probability 3/4, while each non-corner is safe with probability 10/12. From a 20-coin stake, a safe first corner gives 20×0.97/(3/4),about 25.867 coins; a safe non-corner gives 20×0.97/(10/12),23.28 coins. Subsequent probabilities count compatible layouts and may rise or fall.
