Addition Brain Teaser is an HTML5 puzzle game that challenges your addition skills and logic. The goal is to clear or reduce the board by combining numbers according to two simple rules: you may combine equal numbers, or you may combine two or more numbers whose total equals a number already present on the board. For example, you can merge two 3s, or you can combine a 5 and a 2 if a 7 appears on the board.
Play by dragging one number onto others to form a valid group. Valid merges remove numbers and free space, while invalid attempts are canceled. The game rewards planning because each merge changes the numbers available and creates new merge opportunities. Addition Brain Teaser suits players who enjoy quick math exercises, casual puzzle challenges, and educational games that train mental arithmetic.
