Can you make the sums work out? in this game you are given a set of sums in a grid, and a collection of numbered blocks. simply drag the blocks into the slots in the grid, until the sums (across and down) all come to the correct totals. you can choose the puzzle size from an easy 2 x 2 to a near-impossible 5 x 4. you can also choose which operations will appear (out of plus, minus, multiply and divide). there is no limit to the number of puzzles that can be generated for any choice of options, and hints and solutions are also included.
