Level 8 right here.

A huge improvement over the slots IMO. With the ability to lose all the coins you've earned in a single round, there's still some risk involved, but it doesn't go so far as to make you gamble away coins you've already earned, which I think is a good balance.

The only things I don't like about it are that first of all, the levels drop too quickly. Sometimes, you have to make a random guess, and if you get it wrong, you can easily drop back to level 1. I don't have a problem with it dropping you 2 or 3 levels at a time for royally screwing up, but going all the way from, say, 6 to 1 is overkill. There's also the issue with the fact that you can't buy coins like you could in the old games, you actually have to spend the time to play the game. Not like it's an issue for me, I play it even when I don't need coins so I have plenty saved up, but there's always going to be people out there that don't want to bother with the game.
