SUM2ZERO is the innovative card game that puts a spin on zero-sum game theory.
Easy to Play
Each player starts with 10 cards. The object of the game is to place 1 to 3 cards, so that your cards plus the base card add to zero. The first player with no cards wins the game.
Red cards are negative numbers from -1 to -12 while black cards are positive numbers from +1 to +12. Action cards – Boom!, Reset, Checked, Imaginary, Thunder, and Cubit - have been added to give it a twist!
What’s in the Box
104 total cards
- 44 positive number (1 to 12) cards
- 44 negative number (-1 to -12) cards
- 3 positive and 3 negative imaginary cards

Examples:
If the base card is positive 7, a player could throw a negative 7 card.
(+7) + (-7) = 0
If the base card is positive 7, a player could throw a negative 1, negative 2, and negative 4 cards.
(+7) + (-1) + (-2) + (-4) = 0
If the base card is positive 7, a player could throw a positive 8, negative 10, and negative 5 cards.
(+7) + (+8) + (-10) + (-5) = 0
If the base card is positive 7, a player could throw a negative imaginary card (choose the card to be -11) and a positive 4.
(+7) + (-i) + (+4)= 0
