Five games about putting things where they belong: the right group, the right overlap, the right order.
Shortest first, longest last. Each game pays 15 points for a win down to 1 for finishing, and the circuit adds all 5 up. A game played on its own still counts toward it, but you need all 5 in the same day to take a rank on the circuit board.
The same 5 games every day, with new puzzles in each of them at midnight Eastern.
