"Sum Search" is a new type of brain game. It has a bit of Word Search, as you will have to find the hidden numbers in the board although instead of words they will appear as sums. And it has a bit of Sudoku, but instead of applying logic to solve the puzzle you will need to apply simple arithmetics. You will have to sum quickly, you will have to sum correctly, you may need to use your intuition so you focus your search in the right places of the grid, and you will have a good amount of fun and develop your brain at the same time.
