Stack & Crack comes from Jambav, Inc. The object is to slide the tiles around the grid and stack them into 1 pile on the glowing endpoint.
When 2 pieces are stacked, the tower moves in the direction of the tile that's on the bottom. That's a bit awkward.
The puzzles are well designed.  The graphics are good too.  Landing on certain squares makes your tower invert.

There are approximately 100 levels.  I have not done many, but I do like this game.
