Addition Brain Teaser: Another challenge is to add all the numbers together in a math puzzle game. However, there is a catch because you could only add equal numbers or numerals whose total already corresponds to a number on the board. You may add three and three together, for instance, as they are the same. You may combine five and two together when 7 is on the board. Although the total of 5 and 2 are not equal, 7 are on the board.
Control: To play this game, use the mouse or touch. Just click/touch a number and drag it together to other numbers.
