For a long time I’ve had a fascination with puzzle games. Sudoku in particular caught my interest when I learned to play it. I once drew a circular Sudoku board, and it seemed to work. Over the last 4 years I’ve been working with programming and web development, so making that idea into a game was now a doable project.

It turned out to be more work than I first expected. After several weeks it was playable, and the plan was to upload it on WordPress, but I found out doesn’t easily support interactive content. So I decided to buy a personal domain and host it there.

Cirdoku works very much like normal Sudoku, except there are rings and cake-slices instead of rows and columns. To solve it, the player must fill in numbers from 1 to 6 so that each ring, cake slice and same-colored area contain all numbers from 1 to 6 (or 1-8 for large, and 1-4 for small puzzles).

You can now play it here!

I would appreciate feedback and ideas, so please leave a comment here or on Facebook!

To celebrate 17th of May I’ve added Norwegian flag colors to the game!
