How a round works

Build. Judge. Duel. KO.

Four steps, every week. Right now it's step two, and that part is yours.

  1. 1

    Same brief

    Both teams get the same brief and the same deadline: seven days to build.

  2. You are here

    You judge

    Open both apps, cast one vote and leave a line of feedback. The count stays hidden until voting closes.

  3. 3

    Duel

    Each captain picks a player from the other team. Both play the same game. Best of three tries wins.

  4. KO4

    Out

    The duel loser leaves the team. The team that lost the vote gets a handicap next round.

Then it repeats, until a team can't field two players or the rounds run out.
