Independent guide
This independent Kurisumala guide supplies its own free Root Cluster 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.
Uniform connected hazard layouts
Choose3,4 or5 hazards on a4×4 grid. Every hazard must belong to one group connected through shared horizontal or vertical edges. Diagonal contact alone does not connect the group. All52/113/244 legal layouts respectively have equal probability; one random layout is fixed for the entire round.
Expected return and variance
Exact expected return is97% for permitted stopping policies. The initial3% 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.

What is the public layout rule?
Choose3,4 or5 hazards on a4×4 grid. Every hazard must belong to one group connected through shared horizontal or vertical edges. Diagonal contact alone does not connect the group. All52/113/244 legal layouts respectively have equal probability; one random layout is fixed for the entire round.
How is the live value calculated?
Live value starts at0.97 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.
Do first-cell coordinates matter?
With3 hazards, a corner is initially safe in47 of52 layouts, whereas an inner cell is safe in36 of52. From20×0.97 coins, a safe corner gives about21.464 coins and a safe inner cell about28.022. Coordinates matter from the first reveal; unrestricted13/16 or12/15 formulas do not apply.
