No login here
This site has no registration or login form. The demo needs no account; operator authentication and password-recovery flows are unverified. Do not enter credentials into an unverified page.
Unverified destinations
Do not share passwords or one-time codes with unsolicited contacts. A similar domain or HTTPS certificate does not establish the destination’s identity. No example operator login domain is supplied or endorsed here.
Unconfirmed recovery
Use only documented recovery procedures from a service whose identity has been independently established. No support contact, response time, reset-token lifetime or 2 FA feature has been verified 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.
Local virtual coins
Local demo coins cannot be exchanged for money, withdrawn or used as evidence of an operator balance. Settings return to the interface defaults on reload; settled wallet and fractional carry persist. The game is not an authentication or external-security test.
Frequently asked questions
Is this an operator website?
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.
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.
How do reveals change odds?
With 4 hazards there is exactly one hazard in each quadrant. Every cell initially has safe probability 3/4. A safe first choice changes a 20-coin stake’s value to 20×0.97/(3/4), about 25.867 coins. Within that quadrant the next unrevealed cell has safe probability 2/3; another quadrant still has 3/4. Revealing three safe cells in one quadrant proves its fourth cell hazardous.
