Open platform for running game jams, publishing games and sharing assets.
You set up a jam, define voting criteria—custom weights, star ratings or single-vote-per-entry—then open it to participants or restrict it to invited judges. Submissions come in, the leaderboard fills in real time, and the winner list is one click away.
