# Top 5 fun Sudoku variations

Updated on December 23, 2017

## Binary sudoku

For the computer geeks inside us all! Ok then, some of us... What, you think it's too easy?

## Clock sudoku

There's nothing like the perfection of a circle is there? The aim of this sudoku variation is to fill the rings with numbers from 1 to 12 so that no number is repeated in any of the 6 rings, any of the 6 same color pair of wedges or any of the pairs of opposite wedges. As seen on maths.org

## Curve sudoku

The aim of this one is to determine which digits belong in which cells using the clues given which are the greater-than or lesser-than symbols and the difference markers. Greater than symbols establish the relationship between numbers in adjacent cells. Difference markers establish the difference between values of adjacent cells. Each curved line and shaded section needs to contain one digit from 1 to 9 without repeats. This one is pretty tough!

## 3D sudoku or cubic sudoku

In Cubic Sudoku each 2x4 region can have distinct digits from 1 to 8 while each "layer" of the three dimensions on the cube also have distinct digits. Now that's adding a whole different dimension to sudoku games!

## Color sudoku

Using colors instead of numbers is an interesting adaption of the monochrome sudoku games but of course this isn't do-able using just pen and paper, however there are plenty of computer programs out there both free and paid that offer this sudoku variation. It's great for kids who don't particularly like numbers or math, or don't know all of the digits yet.
