Re: UKPA Open Sudoku and Puzzle Tournament 2026

Sudoku round 2: I think there is a typo in the German Whispers solution, R6C3 should be 3 rather than 2. Sudoku round 3: the solution to the Coded Sudoku is +---+---+---+ |763|598|124| |514|632|897| |982|417|635| +---+---+---+ |875|321|946| |439|786|251| |621|954|783| +---+---+---+ |247|863|519| |35...

Re: UK Sudoku Championship 2024

The Quadruple Sudoku in the IB may be impossible - the solution is certainly incorrect - R3C3-R4C4 has a clue of 1234 and an answer of 9123.

Re: UKPA Open Sudoku and Puzzle Tournament 2023

Puzzle Round 5 - puzzles 7, 8 and 9 (Killer Sudoku, Imposter Killer Sudoku and Tetroscope) all have tiny print, will it be this small in the competition (so I know whether to bring my reading glasses)? Some puzzles in Round 4 have the same issue.

Re: Division C and B 2021-22

The rules for Domino Hitori are missing. I assume that it's standard Hitori rules except that rather than shading individual squares you shade dominoes which must not touch orthogonally?

Re: UKPA Open Sudoku and Puzzle Tournaments 2019

Puzzle round 2, Four Winds / Eight Winds - does every cell in the grid have to be used?

Puzzle round 5, Pento Coral - must the pentominoes completely cover the coral i.e. must it consist of exactly 55 shaded squares?

Thanks,
Eva.

Re: UKPA Open Sudoku and Puzzle Tournament 2018

In the instructions for Trio Cut, should the word "tetrominos" be replaced by "triominos" or is it triominos in the example but tetrominos in the puzzle?
Thanks,
Eva.

Re: UK wins the senior category for WSC and WPC

I'd like to know how to become a paid-up UKPA member too. Last time I asked I was told I had a free year for helping out at the 2014 WSC/WPC but that will have expired now.
Thanks,
Eva.

Re: Simple Aptitude Question ( which i cannot solve)

The solution is only unique if you assume that there are no puppies which are not small, are not brown and do not have long hair.
