Dotless comes from Dingyue Ban. The object is to capture all the yellow dots within the allowed number of moves.
  The images describe the movements. However:
1. Blue can move only 1 square at a time.
2. Yellow moves like a rook until it hits a wall or goes off the board.
3. Red cannot move, but acts as a block. Tapping on it removes it. 4. The Blue/Yellow square reverses all the colors.

There are 45 levels.  I'd like to see a 'Level Builder' where users can make their own levels for others to solve.

Dotless is very very good. It's free and fun and challenging. It's a little gem.
