Posts: 191 Country : The Netherlands | Richard posted @ 2013-12-13 10:35 AM Realshaggy - 2013-12-13 5:52 AM I have a question on the Relay Sudoku, just to be sure. Can I be sure that the first puzzle has a unique solution without pulling back informations from the second grid? Yes, the first puzzle has a unique solution without information from the second puzzle. | ||||||||||||||||||

I have a different solution and I don't see any mistakes in it. In your different solution, have you taken into account that there must be a specified number of corresponding digits per row in both grids on the same page? | ||||||||||||||||||

I have a different solution and I don't see any mistakes in it. Of course the XV has multiple solutions on it's own (without the grid to the left). You can see that even without solving. In a unique XV at least one of the givens has to be a 1,4,6 or 9. Otherwise you could use a permutation (1,4,6,9)->(9,6,4,1) to create another solution.

I am notoriously bad at reading the full instructions ... even as I wondered what those numbers in the middle were doing there ... Edited by Bram28 2013-12-14 8:39 PM | ||||||||||||||||||

I attempted the chaos renban only after the test...and found it to be easier than some puzzles worth 30-40 points. I know it can vary with individual strengths, but that's a hell of a lot of variation! | ||||||||||||||||||

Posts: 80 Country : Canada | achan1058 posted @ 2013-12-16 2:34 AM RALehrer - 2013-12-15 3:21 PM I agree. The chaos renban took me 10 minutes, while the other 100 pointer, x is alive took me 20. There's a few others that I think are incorrectly valued too, but the chaos renban is probably the biggest sore thumb I saw.I attempted the chaos renban only after the test...and found it to be easier than some puzzles worth 30-40 points.
