This is a game with just 1 card! A square card with the numbers 1,2,4,3 on the face. The player with the most confidence in math becomes the starting player. The starting player looks at the card's face, secretly chooses one number, pinching that corner with their finger, and flips the card face down. The opponent looks at the back, chooses one of the remaining three corners to pinch. Then, the card is flipped, revealing the numbers each player has pinched. The player with the larger number wins, with the exception of 1 beating 4. The winner scores the "opponent's pinched number." Players take turns being the starting player, repeating the process until one player reaches 6 points, winning the game.
