The most efficient way to play the classic card game (no constant reshuffling the deck). Allows for all kinds of custom rules so you can play the way you like. Finding a random person to play with can be a crapshoot, I recommend either playing with friends or starting a 4-player lobby and starting as soon as a person joins; the game will fill the other 2 slots with AI and if other people are looking for a match, they'll automatically join.
