Turn a real problem into a brief and watch developers solve it live. You choose the Sponsor's Pick award.
Every battle follows the same steps. The server runs the clock, so both players get exactly the same time.
Illustration
Step 1, Before
Each player gets a fresh cloud workspace and signs in to their own AI tool. We never see that login.
Step 2, 0:00
Both players see the brief in the same second, and the server starts one clock for both.
Step 3, 0 to 45 min
Players build and push. Hidden checks, tests the players can't see, run on every push, so fans see the lead change as it happens.
Step 4, 45:00
Glitch calls 10, 5 and 1 minute left. At 45:00 both workspaces freeze.
Step 5, After
The checks run again with speed and accessibility tests. Three AI judges score blind, citing the code.
Step 6, Within 24 hours
Scores post with every citation. Either player can appeal for 24 hours. Fan votes never change the score.
