Sudoku-like number puzzles have been appearing since the 1800’s as far as we know, but the modern form of the puzzle starting gaining popularity in the 1980’s when they became known as ‘Sudoku’ and published by the Japanese puzzle company Nikoli. Today the classic Sudoku puzzles are widespread and new variants and rules are appearing all the time.

For our first foray into the world of puzzle setting we have released Algebraic Thermonuclear Sudoku #01 as a free download! Try it today.

This puzzle is built using Thermo and Killer Sudoku variants (or a slight modification thereof), and the rules are here:

  1. Normal Sudoku rules apply.

  2. Along the thermometer shape, digits must increase from the bulb end.

  3. The grey cells form a magic square (every row/column/main diagonal in the grey square must sum to the same number). The magic square sum is "x".

  4. The dotted lines form cages, the sum of all the digits in each cage must equal the value shown in the corner of the cage. Digits in a cage do not need to be unique

The solution and complete explanation of how to solve the sudoku is also available as a separate download from the link above so you can check your work.

Happy solving!
