Adds are minimal. No need to spend real $$ to progress (just takes a bit of grinding). HATE all the latest updates (Nov 2021, Feb 2022). The power ups have a use timer..preventing u from picking up more powerups...it's like the STEAM edition of game..don't like it. Also the length of time that my speed boosts last have been reduced. I have reduced my stars from 4 to 1. Most recent update w hot wheels dosent help..can only win cars if ranked #1 (not top5). Bad decision.
