Select ‘New game’ on the bottom right of the screen to start playing. You’ll be shown an arrangement of ten blocks, each corresponding to a number key on your keypad. Press the number key associated with the block you want to move. Horizontal blocks can only move left and right across your screen, and vertical blocks will only move top to bottom.

After moving the brown blocks out of the way, you solve the puzzle when the red block crosses the screen out to the right side. The next level will immediately be shown.
