How it works
Build a game with Nimble Fox, solo or in a team of up to five. Building runs from Wednesday’s opening until Friday at 5 pm PST. Submit your game on the Nimble Fox platform before the deadline.
After submissions close, play and peer-review the games on Nimble Fox here: https://app.nimblefox.ai/. The five highest-rated games advance to the judges, who select the top three.
Judges will be announced later.

How judging works:
When submissions close, everyone with a Nimble Fox account can play the entries and rate them from 1 to 5 stars. The 5 highest-rated games become finalists. For each partner prize, the 3 highest-rated other games that used that tool go through. Judges rate those games, and their ratings decide the winners. A game can win one prize at most.
