Whilst I feel the concept of "is it a sudoku" is a little too experimental for a world championship, I find its exclusion because it was too puzzle-ish to be a little strange. If you were erring on the side of caution here, the best thing would have been to can the entire round - but given that didn't happen I felt that the Hamle clues resolved very quickly using simple sudoku-like logic scanning rows and columns, and would have been perfect for the concept of the round.

I imagine its evil "logidoku" twin could also have been made sufficiently awful to solve too!

Can't say I much enjoyed the Touchy puzzle (these are in general not particularly fun to solve), so I'm glad that didn't make the cut. The instructionless also looks pretty tricky, but I haven't yet started to solve it.
