How BC.Game Mines math works
P(this tile safe) = (25 − mines − revealed) / (25 − revealed). With 3 mines and 0 revealed that is 22/25 = 88%.
P(survive r reveals) = C(25−mines, r) / C(25, r).
multiplier(r) = 0.980 × C(25, r) / C(25−mines, r). The 0.980 factor is BC.Game's published 2.00% house edge. That is 1.0% less per payout than a 1.00% Mines board pays on the same reveal.
