Paper Puzzle Masterlist

This is a masterlist of Paper Puzzle Types resources, listing puzzle genre lists, paper puzzle blogs, portfolios and archives, online and paper publications, plus setting interfaces, guides and automatic solvers.

If you're unsure about what exactly is meant by paper puzzle, find the crossword page of any paper newspaper: other puzzles nearby likely fit this paper puzzle definition:

A logic puzzle primarily designed to be printed, then solved by writing or drawing on it, generally with a unique solution for the given rules and constraints, to be arrived at via a sequence of logical steps.

by Pedro

While word puzzles, inductive puzzles and paper-puzzle-like games fall out of scope of this masterlist, any other suggestions (even self-plugs) are always !

Throughout this masterlist, clicking an RSS symbol () will let you subscribe to puzzle updates, while stars (★) mark Pedro's own personal taste and small labels (ENG) indicate up to two page languages, when not primarily english.

To help you answer questions like:

  • How many paper puzzle genres are there?
  • What are the rules of a genre and where to find puzzles and examples?
  • Are there any variants of this genre?

… Let's start the masterlist with this list of puzzle genre lists!

Twitter is no longer twitter. In any case, there's a separate page with twitter handles.

A few authors share their puzzles only via video channels — swaroopg's comprehensive masterlist started tracking those. Sooner or later, those puzzles tend also to appear in the Aggregators.

These are puzzle archives of individual authors, i.e. rarely updated portfolio pages or no longer active blogs. They are sorted by year of latest puzzle posted. Some archives listed here are continued and/or superseded by an active blog.

This masterlist was compiled by gathering the wisdom shared at the Thinky Puzzles server, then following links until information stopped being relevant. Towards the end, swaroopg's list was also consulted, e.g to check for missing entries or uncertain information. Further important inputs were received at the Puzzlers Club (private server).

Finally, many thanks to Menderbug, TheGreatEscaper, Deusovi, Jack Lance, IHNN, dohz, Edderiofer, tckmn, Ammar Fathin Sabili (athin), sevenkplus, Qqwref and Matej Uher (Muhorka) for feedback and identifying many missing entries (and even whole sections)!
