Events are special, limited time missions, where you can collect tokens to unlock a special character. Collect the tokens that appear on the track, and once you have enough you'll be able to unlock the character.
To unlock events you will first need to get your Score Multiplier to 10x by progressing through the game. Once you have a 10x multiplier, events will automatically appear when they are available.
Missed an event and missed out on unlocking a character? Don't worry, we regularly rerun events, so you'll have another chance to unlock the character again soon!
