Haven't tried Mines since I am hooked on slots, though I tried to play tower and I seldom goes above level 3, lol. It looks like there is an imaginary barrier after level 3 in which whatever I pick is an empty cell. That, or I just suck on guessing games T_T.
You should give it a shot. I'm not big fan of Mines nor slots but I have tried it out since playing on roobet always lots of fun. On roobet I played crash a big time of my entire day! For me Crash is working quite simple, it consists of a continually expanding line going up and multiplying your bet. This things make me insane all of the time. Crash Rocket is love!
Might as well try to play Mines when my fund for gambling is available, and see where my luck will bring me. If this works like minesweeper, I might have some luck on guessing where the right boxes but if there is no hint after hitting the right button then possibly the same fate with Tower will happen
