5Fives is a free point scoring puzzle app. It's very similar to 2048 and Threes! The images show the rules.
I was able to solve 5Fives and unlock the next level: 6Sixes. However, I have not played that.
The graphics and interface are very well done. I even like the concept. Hey, it's free.
My high score is 8778, a nice palindrome.
