Bring the four triangular faces back to one colour each. Turn layers and tips separately.
Tap a small sticker. Only that sticker is highlighted. Each active button pair turns a different attached axis in both directions: left/right, up/down, or the curved arrows. Unneeded pairs are disabled. The selected position stays fixed after a turn. Dragging or the joystick only changes the view. At tip stickers, the curved arrows turn only the tip; one straight-arrow pair turns the whole corner layer.
A turn counts as one move. Undo counts as one move and one assist. A solved puzzle has one colour on every face. Different scramble lengths are separate variants.
Tab selects controls; Enter or Space activates them. On the puzzle, all four arrow keys turn layers attached to the selected small sticker. Z undoes a turn. On the joystick, arrow keys only change the view.
Active time begins with your first turn. Menus, background time and demos pause it. Timer display is off by default. The round resumes on this device.
For entertainment only. No stakes or prizes.
