Just wanted to give something back to the developers of this free fun card-game which is very addictive; Tripeaks.
The rules are very simple and go like this:

1) There are 3 stacks of cards
2) Check visible card on left and click on any visible card on right stack which is 1 number above or below card on left.
3) If you cannot click on left stack, so new card will be served (there is number of available cards)
4) Try to remove all cards from right stack to pass level!

Everyone can understand how it works, but it's hard to master. The instructions are also listed in the main menu for you to read again. The graphics are well designed. It helped me pass the time at the waiting room of the dentist like no other app
