NintenDoku is a free daily browser puzzle about Nintendo history. The grid gives you three rows and three columns, each labelled with a category such as a franchise, a genre, a console, a release decade or a critic score range. Every cell has to be filled with a Nintendo game that matches both of its labels, and each game can only be used once. You get nine guesses for nine cells, so a wrong answer costs you a square. A hardcore mode adds a 4x4 grid with tighter categories, and unlimited modes in easy and hard let you keep playing after the daily puzzle is done. A shared result grid lets you compare your run with other players. Answers are checked against a hand-curated database of more than 1,300 Nintendo and Nintendo-exclusive titles, with attributes including release date, region, developer, genre, critic and user scores, average playtime and sales figures. Data comes from public sources such as Metacritic, HowLongToBeat and publisher reports. A new puzzle goes live every day at 6:00 CET.
