Well what do you know, it's not a Friday.  This week's offering is Eliminate Sudoku, a novelty (at least to me!) from the 2014 World Sudoku Championships, where the puzzle was supplied by Ko Okamoto of Japan.  Incidentally if I'm wrong about this and there is an earlier example, then I'd certainly like to be enlightened!  Anyhow, this for me epitomised everything an innovative new variant should be - something which isn't overly contrived or a departure from what the average Joe would know as sudoku, something which compliments the standard sudoku solving logic completely naturally, and something that when you think about it makes you wonder why someone hadn't come up with it before.

The rules are easy enough.  Numbers placed in cells with arrows must not repeat in the corresponding direction.  Enjoy!
