You play first. Click on any blue square to place one of your black counters there.

You will then 'capture' all of my white counters between your two black counters.

Then it's my turn.

We continue to take turns until we are unable to make a capture.

The player with the most counters wins.

I don't play a very good game so you should be able to beat me!

Note that the game is also known as 'Reversi'.
