Simon States is a short-term memory game where there are four colored buttons that that each produce a unique tone. A color will flash white when the game is started. The player must then select that same color. If correct, the game will flash the original color white again, and then another color (can be the same color as well). The player must again select the original color followed by the latter color that flashed. Gameplay continues increasing how many colors flash in sequence until the colors are not correctly selected in the same order. Color Blind Accessible.
