Triangle Flip by Code Handwerker GmbH FREE

  

Triangle Flip is a unique interesting puzzle app game.  The objective is to get all the triangles to be the same color.

  

Swipe over entire rows to change all the colors.  That's the only mechanism. Pretty simple, but things get tough.

According to the Leaderboard, there are about 300 people playing this. I've solved about 100 levels. HRubasch  is #1 with 560 levels solved.
