WPF contests & handmade grids

The WPF coordinates international puzzle sport: World Puzzle Championship (WPC), World Sudoku Championship (WSC), and related calendars. National bodies run opens and qualifiers. Contests & federations on this atlas indexes those doors.

Online Grand Prix rounds are timed. Solving the set early often adds a remaining-time bonus that can outweigh raw puzzle points — speed and accuracy both matter. Exact formulas sit on the organizer page for that season.

Generators fill volume. Human authors plant a intended path, false trails, and a clean break. Neither is universally “better”; the community treats authorship as a craft when the break is memorable.

Contest grids are expected to be unique and solvable without guesswork under the published rules. Blind testing by experienced solvers is normal before a booklet ships.

WPF-style rounds optimize standardized grids against a clock. Team hunts (MIT Mystery Hunt and similar events) mix metas: answers from many puzzles feed a final meta. Different skill mix — bring a team.

Learning & community lists forums and channels (Logic Masters, Puzzling Stack Exchange, and others) where techniques and handmade links circulate. CTC-style video is for watching a path, not for a full library.

Past WPC/WSC sets are often archived as PDFs on federation or community sites for practice. Train there; do not treat this atlas as the archive host.

In a hunt, a meta consumes answers or intermediate data from several feeder puzzles to unlock a final extraction. Tracking feeders cleanly matters as much as any single grid.
