StevenWarner: Hi I'm trying to find the free speed boost. I'm on a Chromebook Maybe I can't get it using that? Can you tell me what I have to do?
As a general rule when replying to searched posts look at the dates. If it's from 2014 (almost 8 years old) it probably doesn't apply anymore or is outdated.
Steps to get "Speed Boost"
1. Jump in your Delorean and 1.21 gigawatt your way back to when the Flash game existed to enable your "Speed Boost"
BTW "Ball Speed Boost" is just the little button that pops up after hitting your ball that makes the ball flight speed up to save time. There is no way of turning it On or Off in the current game.
