Independent query guide
This independent GamGam guide supplies its own free Four Quadrants Mines demo. Operator identity, domains, licence, apps, payments, support and commercial game equivalence have not been independently verified. No operator account or commercial link is supplied here.
Checking 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.
Four disjoint quadrants
Choose 4, 5 or 6 hazards on a 4×4 board. Divide it into four disjoint 2×2 quadrants: top-left, top-right, bottom-left and bottom-right. Each quadrant contains at least one hazard. This rule does not apply to all overlapping 2×2 squares. All 256, 1536 or 4480 legal layouts respectively are equally likely. One layout stays fixed throughout the round.

What is the quadrant rule?
Choose 4, 5 or 6 hazards on a 4×4 board. Divide it into four disjoint 2×2 quadrants: top-left, top-right, bottom-left and bottom-right. Each quadrant contains at least one hazard. This rule does not apply to all overlapping 2×2 squares. All 256, 1536 or 4480 legal layouts respectively are equally likely. One layout stays fixed throughout the 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.
