Four games, each a position already won, and one move that throws it away. The least forgiving circuit on the site.
Shortest first, longest last. Each game pays 15 points for a win down to 1 for finishing, and the circuit adds all 4 up. A game played on its own still counts toward it, but you need all 4 in the same day to take a rank on the circuit board.
The same 4 games every day, with new puzzles in each of them at midnight Eastern.
