Logic puzzle

Deduction and constraint puzzles—grids, narratives, and logic art.

Logic puzzles use explicit rules and finite clues—elimination, propagation, or search—for a unique (or stated) solution.

Subgenres

  • Grid paper puzzles: sudoku, nonograms, slitherlink, star battle, skyscrapers
  • Narrative logic: zebra puzzles, liar/truth-teller
  • Logic art: nonogram pictures, restore-the-image tasks
  • Table logic leading to extraction

Combining elements

Logic often chains with wordplay/indexing/transformation:

  1. logic phase → grid or numbers
  2. indexing/extraction → final word

See Puzzle Elements.
