N-Puzzle is a one-person indie project that makes free, browser-based daily puzzle games about Nintendo history. Every game runs in the browser, needs no account and no install, and resets with a new puzzle each day. Current titles are NintenDoku, a daily grid puzzle where every cell has to be filled with a Nintendo game matching two categories, and Perfect Game, a three-round daily guessing game. Both are backed by a hand-maintained database of over 1,200 Nintendo and Nintendo-exclusive titles, with attributes such as release date, region, developer, genre, critic and user scores, average playtime and sales figures. Data comes from public sources including Metacritic, HowLongToBeat and publisher reports, and is curated by hand rather than imported wholesale. The site also publishes a daily updated ranking of the most popular Nintendo games, built from how often players name each title. N-Puzzle is an independent fan project and is not affiliated with, endorsed by or connected to Nintendo. All game names and trademarks belong to their respective owners.
