Flank the CPU’s discs — most discs when the board fills wins · earn 500 points

Your move (you are the clay discs)

You: 2CPU: 2

Own more discs than the CPU when the board fills.

How to play

Place a disc so it traps a line of the CPU's discs between your new disc and another of yours.
Every trapped disc flips to your colour.
You can only play where you'd flip at least one disc.
When the board is full, the most discs wins.

How you earn

Beating the CPU unlocks the claim; a dominant win pays a bigger bonus.

Tip

Grab the corners — they can never be flipped back, and they anchor whole edges.
