MindGrid helps you develop momentary vision and working memory, by showing a random pattern of squares for an ever decreasing period of time and asking you to recreate the pattern after the grid has been shuffled to a new pattern. Each time you win a collection of puzzles, the game gets faster on your next play, until you are viewing and memorizing all patterns in one tenth of a second.
There are 3 modes to choose from. On the Expert mode, you will be asked to memorize the pattern one line at a time, then recreate it as a full grid.
You may reset the game at anytime, via the settings page, to change the timing back to the default.
