Jigsudo Stage 3: a 9x9 sudoku with a few cells left, number pad with undo, redo, notes and clear buttons, and the rules panel

Jigsudo is a daily puzzle that runs one board through six stages. You find matching pairs of sudoku blocks in a memory game, put the pieces together as a jigsaw, solve the sudoku, then hunt for peaks and valleys, number sequences and a final code. The board is the same worldwide and changes at 06:00 UTC.

About Jigsudo

Jigsudo, made by Corolado, combines several kinds of puzzle on a single daily board. It starts with a memory game: face-down cards hide 3x3 sudoku blocks, and finding matching pairs collects the pieces. In the jigsaw stage you place those blocks in the right positions to rebuild the full 9x9 grid. Then comes a classic sudoku on the board you have just assembled, with undo, redo, pencil notes and keyboard shortcuts.

The last three stages use the finished grid. In Peaks and Valleys you mark the numbers that are higher or lower than all the cells around them, diagonals included. Number Search asks you to find hidden number sequences in the grid. The Code shows a pattern using the last four numbers left on the board, and you watch and repeat it.

The main site at jigsudo.com offers four difficulty levels, from easy to extreme, and also lists each stage as a separate game mode. The board updates for everyone at 06:00 UTC. A history section opens past days, though only the current day counts for your streak and the ranking. With a free account you get a global leaderboard with rank points that reward speed and accuracy and drop if you miss days, plus statistics and cloud saves.

The itch.io page hosts a Basic Edition without leaderboards, statistics or cloud saves. Both are free, with light and dark paper themes and full English and Spanish support. The maker accepts donations through Ko-fi and says the game will always be free to play.

How to play Jigsudo

  1. Open Jigsudo and choose a difficulty.
  2. Memory: flip cards to find matching pairs of 3x3 sudoku blocks.
  3. Jigsaw: drag the blocks into place to rebuild the 9x9 grid.
  4. Sudoku: fill the grid so no number repeats in a row, column or block.
  5. Finish the Peaks and Valleys, Number Search and Code stages to complete the day's board.

Tips

  • In the memory stage, note where each block appears; the same digits show up again in the jigsaw.
  • Use pencil notes in the sudoku stage; the keyboard shortcut W or N toggles them.
  • For Peaks and Valleys, 9s and 1s are usually easy to find first.
  • The board changes at 06:00 UTC, so finish before then if you want it to count for your streak.
