What are Special Events and How do I take part in them

There will now be Special Events that will be hosted in Sonic Dash.
This will involved Special Characters which you can unlock in the game for a limited time
To enter in these Special Events is quite simple as this involves the Jigsaw pieces that you already collect in game every day for Special rewards
On the day of the event, you will see a message box appear on the screen to let you know that an event has started.
Once you enter the race, you will notice that the 4 Jigsaw pieces will now be different icons that you will need to collect on the track, which is apart of the new event.
