Reversi

How to play

Black moves first. Place a disc so that it traps a line of your opponent's discs between your new disc and another of yours.
Trapped discs flip to your colour. If you cannot flip anything, you pass.
Corners can never be flipped, so they are gold. The squares next to a corner are risky.
Whoever has more discs when the board is full (or nobody can move) wins. Hover or focus a glowing square to preview the flips.
