You earn tokens by submitting challenges while the Co-Op Event is live. The more challenges you submit, the more tokens you get!

All challenges in the challenge feed are eligible. My Homes are not eligible.

Tapping the token counter will show the number of tokens granted per filled bubble. 

While the event is live, you'll also see the token counter while designing in a challenge! Go ahead and enter a challenge to see the amount of tokens you'd receive if you submit that challenge!
