Pushing the Sudoku Boundaries!
Try these numberloving favourites!
I was first introduced to Sudoku as a NQT ten years ago and found this puzzle right up my street. I am sure many of you know how to complete a Sudoku puzzle, this article concentrates on puzzles beyond the basic Sudoku. For beginners click here for hints and tips on the classic puzzle.
So what happens when you breeze through [most] sudoku challenges found in newspapers and magazines alike? Or you maybe simply looking for a new logic challenge! Well I recommend the samurai Sudoku. As you can see this joins five classic sudoku to get your brains really working.
Click here for a daily samurai Sudoku, or tap into its archives and puzzles can be printed (myself I prefer to print as a break from the computer). Or there are many books like The Times Samurai Su Doku available through online bookstores.
Way beyond the classic Sudoku is Kuboku a 3D Sudoku cube game created by Creaceed this app, available for £1.49 (at time of publishing). The video below gives a demonstration of Kuboku, don’t forget you get extra Kuboku points if you can complete it faster. You will be interested to know there is no sound in the game, unlike the video!
For a 3D Sudoku in 2D try this flip pad, also known as Tredoku. Tredoku keeps to the same rules as classic Sudoku with the added dimensions or corners which need to be considered whilst completing. Some printable Tredoku available here.
Also don’t forget killer Sudoku, in this game not only do the digits 1-9 have to be placed in the same way as classic Sudoku but you are only given guidance on the total of groups of numbers. Therefore knowing combinations of digits for a given total is helpful. This is an example of one online playing site, there are many available. I use that particular site as its archives are easy to navigate.
New to myself, and frustratingly yet to fully master is the greater than and less than Sudoku, as shown on the right. Again the ultimate goal of placing digits 1 to 9 are the same, however the only hints you are given are the inequalities < or >. I found A day in the Life‘s blog helpful and need to dedicate time to completing one of these over the Christmas break. Play online here, or some print and play here.
The Bermuda Triangle Sudoku game, is a nice twist, with triangle placement of the digits 1-9 as well as colour coordination. Luckily the sound can be muted once the game has begun by clicking on the word sound in the top left corner.
Many of these variations named above are available online, or as a downloadable app for those with a smartphone and on the move. Here is a list of recommended websites for Sudoku.
