Unlock the arrows to free the monster trapped inside.
Tap an arrow to slide it out of the cube.
Only the head matters. An arrow leaves along the direction its head points, straight to the edge of the face it sits on.
If another arrow sits anywhere in that path, it will not budge. It shoves and stops, and the arrow in its way flashes white. Clear that one first.
Arrows bend at right angles and wrap around the cube's edges. The tail shape never changes the rules.
A raised block with a number on it is not an arrow. It cannot be tapped, and it stops any arrow pointing through it. The number counts how many more arrows you must clear before it drops away on its own. The low plain tiles with no number are part of the cube itself and never move.
Drag anywhere to spin the cube.
It can never be made unwinnable. Hint always shows a safe move.
