These slot machine are worse than real slot machines. You can bet 100k over ten times without a single pay. I would never buy coins for this rip off. Seriously this game is getting worse, I know you want to make money but I won't buy coins when these slots don't pay. You get 150 bonus coins and to go up levels you need at least 250 for just 1 slot machine, and as for winning 2 or 3 times in a row you obviously you havn't played your own game, as it can take forever and all your coin.
