Once, I have tried a Five - player game. It was difficult to follow and keep all the turns in mind for the right order, maybe you start a two player game. It works like in chess, if you switch white/black each turn. The problem is, you know always the strategy of your opponent...
But a lot better: Try GCCG, it is a programm, which allows you to play free with players all over the world. It makes fun to meet people, and friends. You can train your language skills, exchange news, chat, oh - and play with any deck or format you wish!
