Red & Blue (HorizonZz)

Red & Blue is a short and fun math game that can be used to practice addition and subtraction. Once you place a card in a slot, you won't be able to pick it up, so be careful! The aim of the game is to make both the red and blue sides equal and to use the highest amount of cards to achieve that.
