Your goal

Six squares on the board are blue. Roll the cube onto a blue square and that colour sticks to the face underneath; roll a blue face onto a plain square and it puts the blue back down. Get all six blue squares onto the six faces at once, in as few moves as you can.

How to play

Tap the board on the side you want the cube to roll towards. Keyboard: the arrow keys roll it. Type also offers a tetrahedron, an octahedron and an icosahedron on triangular grids.

Tips

A blue face is safe only on a blue square. Plan routes so that faces you have filled land on squares you have already emptied.
Count which face is underneath before each roll: four rolls in a straight line bring the same face back down.
The move counter is your score. Try the same board again to beat it.

Use the board’s Type menu to choose a size or difficulty. Undo and Redo let you explore. Solve reveals the answer when you choose it.
