Description: Add Em Up is a rather unique and fun puzzle game. It is a combination of Sudoku and math games, but it doesn't play exactly like either of them. The gameplay is a little hard to explain, but the in game tutorial do a good job with step by step instruction. Your goal is to add up number that equal to the highlighted area to clear it. A very cool game indeed, try it and you might get addicted to it. It is also an educational game for kids.
