Fast Speed

Fast speed is a speed setting on Google Snake Game in which the snake moves 1.5 times faster than Normal Speed. It's coded that each tile takes 0.66 times as long as normal speed (135ms times 0.66). Each tile takes 89.1ms of travel time.

This used to be it's own game mode in the past, so you could only play "Classic" mode with it, but it was changed to a speed setting instead in a later update.
