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.

Does the Sudoku XV in the IB have 2 solutions? 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?

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.

In the coming days I will publish some more practise puzzles (other types than above) in the portal of Logic Masters Germany. I will keep you all informed about it.



The last two practice puzzles are online:
Sudoku XV: easy
Missing Arrow Sudoku: easy

Have fun with these last two appetizers!
I wish all participants a fun and pleasant test. Good luck to all!

Is online solving enabled for this test?

Since this is not yet answered, does this mean online solving will not be available?

Right, we are not having online solving this time. I was hoping to get it done this week, but tied up with many other things to focus on online solving (which needed a minor change in the interface because of IG)

Only one of the rules is true. It is part of solving to figure out the correct rule. See Sudoku A or B IB for more details.

so it means that only the two cells where clue is given in center are of importance. And then the clue is either greater or smaller than other digit that will be part of those two cells ?

The number in the clue is greater than the other cell for ALL given clues

OR

The number in the clue is smaller than the other cell for ALL given clues

hie
i think entering 5 at r2c5 itself is a wrong step , in that row 5 can be at r2c8 :)

Ah! No, I had not. I am notoriously bad at reading the full instructions ... even as I wondered what those numbers in the middle were doing there ...

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!

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.
