Strangely addictive. – Ace Miner Tycoon Review

This game really appeals to my obsessive-compulsiveness. It maxes out at 8 slots, though, so the game's kind of over after that. Also, it will SAY you have a ninth slot, but if you try to buy a mine for it you will just get an error message. This has the potential to be a great game, if there could be some sort of progressiveness to it. Not worth spending real money on for the short time it takes to max out slots, though. I think it took me about a week or so of very casual play.
