But the question is how can you determine on which tiles are mostly being clicked? This is why i do really have negative doubts on this one because i dont really believe that you can able to exploit the house itself.If they are not fair then i guess having some patterns would really be discovered.but how??
Well if it's per-player you can bet a bunch on the same tiles many times in a row then bet on completely different tiles. It could possibly be possible to exploit a house doing this, but it depends on if they take into account the amount of the wager and such. But remember that the house is completely in control of what tiles the mines end up on for every game.
