Greater than less than sudoku

Another common sudoku variant is greater than, less than sudoku.

This one can be a real nightmare to work out!

Basically you have to work out which number is in each cell by working out what it must be logically in relation to the other numbers in the 3 x 3 by seeing how many of them it is greater than and how many it is less than - in combination with the standard sudoku rules of 1 - 9 only once per row and column.

It can be a little difficult to get into but for minds that like more of a challenge than normal sudoku, it can be great fun!
