Why paper puzzles

Screen-free thinking time

A printed puzzle sits on the table without notifications. You can make notes in the margin, leave it half-finished and come back later, or share one sheet between two people.

Sudoku needs no arithmetic: numbers are simply symbols that must not repeat. That makes it approachable for children who are still learning their number facts, and absorbing for adults who want a calm puzzle.

Crosswords stretch vocabulary and general knowledge, and spot the difference trains careful looking — both are good with children. The Kids Worksheets section has maths and English practice with answer sheets, and the graph paper generator is handy for drawing your own grids and games.
