> 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.

Other channels
==============
A few authors share their puzzles only on twitter (now X) or via video channels -- @Swaroop's [comprehensive masterlist|https://github.com/swaroopg92/penpa-edit/wiki/Puzzle-Blogs-and-Sites#Twitter_Puzzles_tweeted_frequently] tracks the latter, whereas a [separate page lists some twitter handles|paper-puzzle-twitters].
Sooner or later, those puzzles tend also to appear in the [#Aggregators].
Archives
========
These are puzzle archives of individual authors, i.e. rarely updated [#portfolio pages] or no longer [active blogs|#blogs].
They are sorted by year of latest puzzle posted.
Some archives listed here are continued and/or superseded by an active [#blog]
