Jigsudo
Jigsudo is a browser-based logic game that includes six stages: Memory, Jigsaw, Sudoku, Peaks & Valleys, Number Search, and The Code. You complete them in order, using what you learn or create in one level to advance to the next. Sudoku is at the heart of the game, yet completing its grid is only part of the task.
How to Start a Jigsaw Puzzle
Choose Daily to take on the day's challenge, or Custom to create a puzzle with your desired difficulty and levels. The difficulty levels available are Easy, Normal, Hard and Extreme. If this is your first game, play through the phases to see how the board is constructed.

The six stages: a breakdown
From hidden pieces to solved puzzles
Memory Flip the cards and remember where the Sudoku blocks are the same. "Finding pairs reveals the pieces needed for the board.
Put the pieces back in the right places to form the 9x9 grid.
Now fill in the reconstructed grid using Sudoku logic. The numbers 1-9 must appear exactly once in each row, column and 3x3 box.
Three Other Ways of Reading the Board:
- Local highs and lows: Compare numbers with those in adjacent cells to find highs and lows.
- Number Search: Search for hidden number sequences in the filled grid.
- Code: View the last number sequence and repeat it to complete the challenge.
- The order is important: Memory supplies the pieces, Jigsaw generates the grid, and Sudoku fills it.
- The final three phases ask you to examine the completed board in various ways.
Tips for Each Part of the Challenge
- Instead of randomly drawing new cards during Memory, keep track of the ones you've already revealed.
- Before you put a piece in Jigsaw, make sure the numbers line up and the blocks line up.
- In Sudoku, the provided numbers can be used to eliminate options from a row, column, or 3×3 box.
- During Peaks & Valleys, compare a candidate number to its neighbours before picking it. Accuracy counts, as mistakes can decrease your rank points.
