Trifecta is an addicting tile game that will keep you occupied for hours.
The object of the game is to get rid of all three layers of tiles. Tap the screen to roll your dice, then choose up to three tiles such that the sum of the tiles is the same as your dice total.
For example, if you roll a 5 some possible selections would be a 5, a 1 and a 4, or even a 1 and two 2s.
Great for both when you only have minutes to spend or when you have hours.
