4 digit Sudoku
99 words, 1 imageI was excited to learn about the Independent’s Saturday hexadecimal Sudoku, consisting of a 16×16 grid, made up of 16 4×4 grids, into which you place the numbers 0 to F.
Of course, you can use any square number to make a Sudoku variant, so for your entertainment and edumacation (edumertainment, if you will), behold 4 digit Sudoku.

Fill in the grid so that every row, column and 2×2 box contains the numbers 1 to 4.
Apologies if the table isn’t quite square: I gave up fiddling with it.
