Start by covering your corner.
After that, your color may only touch at corners.
Your own pieces cannot touch side-to-side.
Use Turn and Flip buttons (or R and F keys) to change a shape.
If you cannot place anything, click Pass.
The game ends when everyone passes in a row.
Cycle each color between Player, Bot, and Off. Keep at least two colors enabled.
