PROOF+ is a math-based card game designed to enhance arithmetic skills. Players use number cards and operation cards (+, -, ×, ÷) to create valid mathematical equations. The goal is to be the first to get rid of all their cards. Gameplay typically involves a communal "proof area" where players build equations. On their turn, players can either add to an existing equation, create a new equation, or discard a card if they cannot play. Wild cards, often represented as a "Joker" or similar, can substitute for any number or operation, adding strategic flexibility. The game requires quick thinking, a solid understanding of order of operations, and the ability to spot mathematical relationships. The plus sign in the name suggests an emphasis on addition, but all four basic operations are typically utilized. Variations exist, but the core principle remains the same: use your cards to create and complete mathematical proofs.
