Yeah but ...

This could be a great game, but it is flawed.
Its very hard to get the 100 coins needed to open a box. Either you have to play lots of games or watch lots of ads.
Imagine the frustration when you finally got the 100 coins together and then win a car that you already had. For the third time.
This totally ruins the experience. No incentive in playing.

Update: Thanks for the update, but the biggest flaw remains. See above.
