About the Game
SUMMATION™ is a fast-playing, turn-based card game where players use numbers, operators, and wild cards to form equations that match a target number (SUM OF X).
The game is designed to blend quick thinking, strategic decision-making, and mental calculation in a way that is easy to learn, fun for all ages, and highly replayable.
Each round begins by determining a SUM OF X — a number between 11 and 20 that becomes the target for all players.
Players start with seven cards and take turns either forming valid equations that reach the SUM OF X or drawing a card.
All equations must start with the Last Card from the discard pile (Last Card Rule™), and number cards placed side-by-side automatically sum thanks to the Auto-SUM™ mechanic.
SUMMATION™ is ideal for families, classrooms, and casual players who enjoy clever card play and math-based strategy without unnecessary complexity.
Easy to learn. Infinite ways to win.
