You played as a wizard. Each wizard had spells they were good at. We all invented spells then they were shuffled and redistributed among everyone so everyone got some low level spells and high level spells. We also had common spells which everyone could learn like basic spells. You play by using your spells on your target and everytime you used a spell, you were becoming more exhausted and eventually you ran out of stamina to cast more spells. So you had to choose your spells carefully - but when I played against Tom, I lost quickly since I didn't learn and defensive spells.
