About Grayscale
Grayscale is a game where you have to see the background appearing color (Black/White or Gray only) and then click on the same color box till the time more boxes are there. You fail once and you are gone. Timing is the winning factor so please do it as quick as possible and dont get confused in colors :) Grayscale is unblocked on SolveCalcPro: it runs directly in this page, with no sign-up and no download, so it works the same way on a school Chromebook as on a home computer.
How to play
Click on the same color box that just flashed in background
