Play is the same as for 4 players, except that a fourth trading card is dealt face up to where a fourth player's trading card would be. Players may trade for this card by exchanging it for the top card on their own trading pile. Or, players may trade for it, plus the top card of the Draw Pile as well, by replacing it with the top two cards on their own trading pile. In this way, the fourth trading pile can grow. Play is the same as for 3 players, except that a third and fourth trading card is dealt to where a third and fourth player's trading card would be dealt.
Players can trade with either on their turn.
The play of these versions is slightly different than for 2-4 players. The entire deck will be dealt out and there will be no draw pile. If six are playing, deal 9 cards to each player. If five are playing, deal 11 cards to each. Trading is different in 5-6 player games.
