About GridJoy

GridJoy's Daily page describes itself as a new daily Sudoku and number puzzle, the same for everyone: solve it, share your time and come back tomorrow. Alongside the classic Sudoku there are 17 more formats, including Killer Sudoku, Kakuro, Takuzu (binary), Calcudoku, Hitori, Sumplete, Skyscraper, Inequality, Number Crossword, Number Blocks, Countdown, Shikaku, Starlink, Number Maze and three kinds of maze (hex, square and circular).

Each day one of them is the Global Daily Challenge (on 2 October 2026 an expert Hex Maze), served as the same board in the Android app, in the browser and in the day's solution video. Every board from the past week stays playable, so you can catch up on missed days.

The site is free with no ads and no sign-up. A streak system rewards regular play, for example with a streak freeze after seven days, and there is a Learn section with rules and tips for each puzzle type. The Android app on Google Play carries the same dailies.

It suits sudoku players who want variety and anyone looking for a single place for many daily logic grids.

How to play GridJoy

1. Open the Daily page and pick one of the 18 puzzle types, or the Global Daily Challenge.

3. Solve the board; your time is recorded.
4. Share your time and come back after midnight UTC for new boards.

Tips

• Try the Global Daily Challenge first; it is the one everyone is talking about that day.
• Use the past week of boards to practise a new puzzle type.
• Keep your streak by solving at least one daily; a freeze covers one missed day.
• Start unfamiliar types like Hitori or Takuzu on their rule pages before timing yourself.
