Want to have fun practicing math problems with FOUR addends?!
The goal of the puzzle is to arrange the pieces so that the sum of each horizontal row equals the Target Sum. The current sum for each row is displayed on the far right side of each row... in green when it matches the Target Sum.
The catch is you can only slide one piece at a time to the empty square. And, only pieces directly adjacent to the open square can be moved. The final puzzle piece is displayed below the grid and must be dragged to its correct location as the last move. The last piece must be placed even if it is zero.
All Target Sums in this game range from 3 to 10.
