01 / TAKE TURNS

Pass. Play. Think.

Challenge someone beside you on the same device, or play against a computer that learns from games on your device.

02 / FIND YOUR SHAPE

Choose Triangle, Square, or Diamond. Each board brings a different set of possibilities.

03 / MAKE IT YOURS

Place circles, choose a color, and save your creation. Play custom boards against a friend or the computer.

Select 1–3 adjacent, unmarked circles along a straight line, then confirm. Players alternate turns. Whoever marks the final circle loses.
