Think carefully before you make moves, for you can only undo one.

Clear all the cards from the board!
Eliminate one card from the screen pile by tapping the number higher or lower than the number shown at the bottom of the screen.
The cards that are left on the screen determine your score and the number of stars you will receive.
No cards left gives 3 stars, under target 1 card left gives 2 stars, and 2 cards left gives 1 star, if neither of those, you have to try again!
Make good use of the bombs to change the order of the numbers when you're in a pinch.
You cannot undo the usage of the bombs so be careful!

Are you ready to do some shufflin'?
