Grid puzzles are puzzles built on cells, rows, columns, regions, lines or intersections. The grid might hold numbers, letters, shaded squares, paths, ships, lights, stars or word clues, but the appeal is the same: each small local decision changes what the rest of the board can be.
This roundup is deliberately broad and scan-friendly. It does not go deep on any one ruleset; instead, it gives short summaries for as many grid puzzle types as practical and links to the Logic Puzzles Online game whenever we have a playable version.
The article targets grid puzzles, logic grid puzzles, number grid puzzles, word grid puzzles and online grid puzzles.
The list covers classic newspaper grids, Japanese logic puzzles, Sudoku variants, picture puzzles and placement grids.

For picture-style solving: Nonogram, Mosaic, Nurikabe, Yin-Yang and Shikaku.
For paths and loops: Slitherlink, Masyu, Numberlink, Hashi and Yajilin.
