It's nothing to do with them, I've just always been crap at strategy games.
Lol you can't be good or bad at it. It is not even a strategy it's gambling. Pure luck so don't feel bad ^^
It is fun though isn't it ? xD So addictive.
I always play with the at least 0.01 btc . I play like when I deposit I start the game and just click on cashout to check that what is the location of the mine bomb. I keep continuing with it till I came to know that it will be on one of the corner. I bet with just 0.0005 btc though I deposited 0.01 and I won 0.01 plus deposited amount .
This is the only strategy I use to play on satoshimines.
It was the strategy that I have ever done, but because I don't have the patience or too greedy in the benefit then I decided not to do it again. because in the game I have to always be patient and sometimes the patience not to yield satisfactory results.
