In case of opening mines, game is over and you will lose. Maximum amount of mines is 24 and minimum 1. The more mine is hidden in the box, the higher is the value of each coin.
You are opening the boxes one by one and you can cash out the winning at any time. You can open boxes by random.
So do you take one more box or not?
The house edge in Mines is only 1 %, which can be considered very low.
