Schulte Grid is invented by Doctor Schulte for the training of attention and speed reading. You need to select all the numbers in the correct order in a 2x2-9x9 grid as fast as you can. The difficulty of the game is gradually increasing with the grid size. If you are practicing speed reading, this program may help you. The longer the practice, the shorter time needed to read the whole table.
