Fast Forward

Fast Forward speeds up the game to allow for quicker rounds. It can be toggled by the player at any time by clicking/tapping the "Fast Forward" button. It was introduced in Bloons TD 4 and has been in every BTD4 version.

On April 14, 2011, Fast Forward was updated to work as a toggle so you don’t have to hold down the mouse any more. Before this update, the player would have to hold down the fast forward button for it to be enabled. As soon as it was un-clicked it was be disabled. It should be noted that the iPhone/iPod Touch version of BTD4 always had the fast forward work as a toggle rather than having to be held down.
