Twist all cubes to same appearance!
Attention! Cubes are twistable in bundles only ... At the beginning of the game only a couple of bundles get twisted. In order to rise up the difficulty just mix again (and again ...) until you feel challenged.
Attention again: for crazy brains only!

By activating the Switch-option you switch between two modes: 4 bundles of four cubes or 6 bundles of three cubes (per row/column like shown).
