There was a formula for the Rubiks Cube , and colours are easier than numbers. This cubes got me stumped, the 1 can start anywhere, its hard enough just to get a 2 the right way up next to it. If theres no formula its going in the bin……soon

what’s the most easiest way to solve it?

I can’t seem to get it. And I can’t find anything to help me get it. It’s like a rubiks cube but it has the sudoku numbers instead.
