Pop 8 is a point scoring puzzle app game.  The object is to shift your tiles, one at a time to an adjacent space so that they can be popped.

A 4 tile will be popped if it's next to 4 other tiles. You get the idea.  After each move, a new tile randomly appears.  Or does it appear randomly"  It seems that a new tile always appears at the spot where I've moved a piece.
The blank squares....I haven't quite figured out how they work yet. The instructions aren't clear.

After playing this 5 times, my high score is 111. Each game takes about 10 minutes.

Definitely give this a try and then check the leaderboard to see what the top score is. Not sure what it is, but I'm impressed.
