PSEUDOKU - CROCHET

Three Sudoku solutions in one design. It fulfils all Sudoku rules three times over forming 81 unique squares.

Each row, column, and block of nine squares, uses each colour only once for each of the three sizes of square.

It is based on a page from Snowflake, Seashell, Star : Colouring Adventures in Numberland by Alex Bellos and Edmund Harriss, but does not use their arrangement.

CONSTRUCTION INFORMATION

There are 81 different squares which are made individually and joined later. Care has to be taken to arrange them in the correct order.

The squares can be crocheted, or sewn together.

The pattern includes a simpler version which only has nine different squares,

CROCHET INFORMATION

Any type of yarn can be used. Equal amounts are needed in nine different colours.

The finished piece is shown here as a wall-hanging, which is 120 cm (48”) square. It was made using DK yarn.

The pattern includes information for adapting the squares to change the size of the afghan.

The afghan is based on a design from a mathematical colouring book by Alex Bellos and Edmund Harriss. Their original design used squares inside squares inside squares in the same manner as this one. We particularly liked the optical illusions it created where some squares appeared to be bigger than others, depending on the colours and combinations.

We used their arrangement of numbers to make Pseudoku - Knit but we chose to represent them as L-shapes instead of squares. This was mainly for ease of construction for knitters and created a very different effect.

We then decided to use crochet squares to replicate their original optical illusion and also decided to use three Sudoku solutions that would result in 81 different squares.
