Equation Builder is a three-tiered mathematics-based deck building game that teaches Pre-K to 8th grade.
Players begin with a 10 card personal deck from one of six decks (red, orange, yellow, green or purple) made of single digit number and mathematic symbols. Which is used, on their turn, to create their best equation.
Players earn cards, depending on their knowledge, from up to four decks (the community, copper, silver or gold). Earned cards are added to the player's personal deck and used in future equations in the game.
The game ends when one of the non-personal decks has been exhausted or after a preset number of rounds. The players count points gained from their cards. The winner is the player with the most points.
