If you like games like Othello or Reversi then you'll enjoy Desdemona. It's a tricky little brain-workout of a game where you have to outwit artificial intelligence to trap the computer's black pieces between your white ones.
Each trapped piece then changes colour to that of the other player.
Desdemona is a challenge and draws on the old established formats making it an extremely comfortable to game to get your teeth into.
I managed to sneak a couple of wins out of the machine - attack the corners is my best advice.
You might get sick of Desdemona's annoying catchphrase - Sorry but I was better this time.
