Once you figure out how it works, you can start to easily win bigger, provided you are not too greedy. Just one day ago, I was content with leaving with 4k chips. Today I cashed in 40k, 60k, and even a 240k once, which is a pretty awesome return for risking a grand total of 200 chip.
It's a good game to get coins off of but only if your lucky. You can use a bit of logic to help build an advantage but when it comes right down to it luck is still the name of the game. The stakes are really low for the payout it's just knowing when to stop that will end up making you a profit.
