Sorcerers is a free turn-based multi-player fantasy battle game. Once you have downloaded the app, you can play as many games as you want.
This game is played in a casual way. When you have taken your turn, your opponent is notified by e-mail that it is now their turn. However, they may not take it straight away. Typically, expect to take a turn and then wait about a day to take your next turn. Of course, you can play as many concurrent games as you can handle if you get bored in the meantime.
