if there were 5 guys instead of 2 they each bet on a different number 1-5. 4 guys lose 1 each roll. one guy wins 5 bets. house loses a bet each roll. they can go up to their room and split the money. each guy made 1/5 bet profit per roll.

take the original example but make it a four card deck and have three players instead of 2. one player sees the top, one guy sees the 2nd card, and the other guy sees the 3rd card. one guy will be wrong every time. two guys right. the house will lose a bet every time. when the guys go up to their room they split up the money and made 1/3 bet on each hand.

with a 52 card deck, same thing, but house gets suspicious when 51 guys try to squeeze into a room.
