Sum Attack! Addition & Subtraction

Sum Attack! Addition & Subtraction is a fast-paced card game where players race to empty their hands while practicing math facts. It was designed by a California-certified math teacher to help kids ages 5 and up build addition and subtraction fluency.

Each player starts with 7 cards. On your turn, play a card that matches the top of the discard pile by color or by value. Equation cards count as their answer, so a 4 can be matched by another 4, by 2 + 2, or by 6 − 2. Icons on the cards work as built-in counters, so younger players can count to solve equations. If you can't play, draw a card. The first player to empty their hand wins the round.

Action cards keep every round unpredictable: Reverse changes the direction of play, Brain Freeze skips the next player, Double Trouble makes the next player draw 2, and Wild and Wild Draw +4 can be played on any card. The signature Sum Attack! card has players add the values of the last two number cards played, then hand out that many cards to opponents, with no more than 6 to any one player.

The deck includes 121 cards.
