Logic Puzzles (Puzzleship)

Each puzzle sets a scene, such as librarians and the patrons they helped or detectives and their cases, and asks you to link every item across several categories. The clues rarely give a match outright; instead they rule out combinations, and the grid lets you record matches and exclusions as you go.

When you mark a match, the rest of its row and column in that block is crossed out for you, which often leaves a single option elsewhere. Matches carry across categories: if a person goes with a city and the city with a year, the person goes with the year. Puzzleship also sells printable collections of these puzzles.

Puzzleship publishes six puzzles of Logic Puzzles a day, graded from very easy to ultra hard. Each day's puzzles are numbered and dated, the same for every player, and come out at 13:00 UTC (the page itself says midnight in your own time zone, but each set is scheduled for 13:00 UTC); earlier days stay playable in the archive. The site is free with ads, including a banner above the grid on a phone, and a premium plan removes them. No account is needed to play.
