Rules
1. This game is played as a 5-card draw. The dealer will pass
out 5 cards to each player from the shuffled deck, placing all
remaining cards in a central stack.
2. Each player may discard as many as 3 cards in one
rotation—taking as many cards from the central stack as
s/he discards. Play begins with the player to the right of the
dealer. Players try to make a chemical formula that uses as
many of their cards as possible. If they cannot play, they
must pass. It is possible to make two chemical formulas in
one play. Once a player uses a number of cards to make a
formula, that player should draw, from the central stack, as
many cards as s/he used. Play then passes to the player on
the right.
3. Total the score by the number of cards that a player is able
to use to make a chemical formula. It is possible for a player
to score as many as 5 points per hand. See Sample Score
sheet. Each player has her/his own score sheet.
4. Play continues until no more formulas can be made.
