Sudoku coming to a Tablet PC near you


Peter Wright is a sneaky guy. Buried deep in a post on his blog is a link to a secret project that should go beta in a couple of weeks. Inkudoku is a Tablet PC version of the game Sudoku that is sweeping the world by storm. I even saw a “Sudoku for Dummies” book in a Border’s book store recently. The Tablet PC is the perfect platform for a paper and ink game like this and I for one can’t wait to see Peter release this. From the Inkudoku web site:


  1. Ink enabled for Tablet PC
  2. Includes the Loops and Bridges number games
  3. Symmetrical patterns
  4. Puzzles are seeded with cryptographic random number generator
  5. Make notes anywhere on the puzzle, just as you would on paper
  6. Inkudoku can quickly give you quickly hints at where you went wrong
  7. Elegant, minimalist user interface

Thanks for the link James.

To answer the first comment, yes there is indeed a Sudoku widget available for Windows, and yes you can ‘click’ on the buttons with a pen. But where’s the fun in that? ;)

The whole experience of Sudoku is best sampled with a pen actually physically writing numbers, scrawling notes next to the possible, noting possible solutions in a cell. Hence Inkudoku.

In addition, Sudoku in Japan spawned a raft of pen and paper number puzzles two of which are utterly fiendish; bridges and loops. In many respects they are like minesweeper in that you have boxes with numbers in. In the case of loops, the numbers dictate how many sides of the box have a line on. With bridges the numbers indicated how many ‘bridges’ (no more than two per compass direction) join that box to another box. It’s hard to explain in text, but when you see them you’ll see why I got excited enough to start putting them into software.

The first beta though will just have sudoku and some elements of the new UI paradigm (credit where it’s due – it’s inspired by the pop up UI in Apple’s new iLife 06 suite).


Sweeeet. I picture it like the Ink Crosswords. Actually, I wouldn’t be surprised if an Ink Enabled version of Sudoku made it into the next version of the Tablet Experience Pack.



If you use Yahoo Widget Engine, there already is a Sudoku widget by Andrea Arevalo that works great with a pen… all you have to do is tap the numbers…enjoy!
