Welcome to GMPuzzles!

On this site, and with our partners, we showcase “The Art of Puzzles”, with hand-crafted logic puzzles by the best puzzle designers for all who love puzzles. If you’re new to logic games, you might want to start with the daily puzzles we share through partners like LinkedIn, including Mini Sudoku (6×6), Queens, Tango, and Zip.

On this blog we share many other games and a broader range of difficulties. We organize into the categories of Sudoku, Number Placement, Object Placement, Shading, Region Division, and Loop/Path puzzles with tags on each post to find the easiest/hardest within particular styles. There are also many puzzles in our subscriptions and books so check out our Store for more details and to support our puzzlemakers.

New to the site and to logic puzzles besides Sudoku? Here is a web intro to Tapa, a great shading puzzle invented by Serkan Yürekli, our managing editor, with example walkthrough and a curated set of puzzles from our archive. Also check out our books like Intro to GMPuzzles and the Starter Packs for great beginner series.

Since June 2025, we’ve been running the “Twelve Months of Sudoku?” project, where we take a year to see how far we can push the limits of sudoku, with new partners, projects, and different things than we’ve ever tried to do before. This includes:
