It is a very easy game that allow you to enjoy for a bit. You can get all the achievements in less than 2 hours and its graphics are not good, but enough to have a funny moment to release stress.

Regarding to the drops, you can get all of them (3 units) during the time you spend to get all the achievements. Them are not expensive cards.

I paid 0,49€ (euro) for the game, but a friend told me that sometimes is about 0,33€ (euro).

I hope this review helps you!
