Every week of the plan gets a game built for that week's subject. It is not a break from the week. It is the same week, faster, and against a clock.
No game is built for this week yet. The ones that are built are below, and they are all still worth a run.
A best score is kept in this browser only. It is not a standing and it is not on the board. The board reads from the record on the server, which is a different thing on purpose: a score you can beat by opening a private window is not a ranking.
