Choose a puzzle
The arrows are on the outside of a cube. Tap an arrow to slide it off along its own line, head first. It can only leave if nothing is in front of its head: straight ahead to the end of its side, and over the edge to the end of the next side.
Drag the cube with your finger to turn it any way you like. The Turn buttons give a quarter turn. You have 5 blocked taps on each puzzle. If you use them all, you try that puzzle again. The Hint button is always there, and there is no timer.
Your progress is saved on this device only.
