: A challenging math puzzle game where all you have to do is add all of the numbers on the board together. but there is a catch as you can only add equal numbers together or numbers whose sum equals a number already on the board. for example, you can add 3 and 3 together because they are equal. if 7 is on the board you can combine 5 and 2 together. although 5 and 2 aren't equal their sum is 7 which is on the board.
Use mouse or touch to play this game. just click/touch a number and drag it to other numbers you want to add together.
