single system 1 - 4 player turn based tutorial?

i have a nearly finished game, all i need to do is make it so my players act on turns instead of all at once, but i cant find a tutorial that shows how to do turns for more than 2 players. can someone point me to a good one? anything from darts to a tactics game to just moving 4 cubes would work as long as its turn based 1-4 players
