The variations

The rule of Quiltoku is always the same: every row, column and box holds each mark once. Everything else is a variation on what the board looks like and what you have to look at. Each variation has its own guide.

• Latin boardsNo boxes, just rows and columns. Includes the story of Euler's thirty-six officers.
• DoubleTwo separate puzzles on one board, a big square and a small circle in every cell.
• ScrambleEvery mark wears a decoy. Only the real colour or shape counts.
• Colours, shapes and patternsThree kinds of marks, and the accessibility modes for players who cannot rely on colour.
• Turned boxesThe same rule with the boxes on their side.
• Inside the logoA ten-by-ten Graeco-Latin square in fabric, and a finished puzzle hiding in its corner.
