At the beginning of each level you will see a bunch of colored numbers. After a couple seconds, a group of either numbers or colors will disappear (for example, all the blue icons will disappear). Then you have 10 seconds to examine the remaining icons to try and figure out which color or number disappeared. Note: At the botton of the screen it will say whether colors of numbers disappeared. If you want to get bonus points you can click to make your guess early. When all you options of colors or numbers will appear, you have a few seconds to select your pick. Use YOUR MOUSE to control the game. Good luck!
