This test contains a lot of sudoku types of which I didn't make a puzzle earlier.
For that reason the list of links to extra practise material is not so long as usual for my tests.

Non Consecutive Killer: very easy; easy
Odd-Even-Big-Small easy; average (scattered grid)
Chaos Renban easy
Rhombus Sudoku average
Scattered Sudoka average

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 rule is applicable on given clues.and that too if in any row or column there are two or more clues given.
Considering IB example: In c1 clues given are "9_6" so between 9 and 6 only 7 or 8 can come. Now consider c5, Between 6 and 1 only 2,3,4 or 5 can come. and between 1 and 9 of course any digit. Hope this clears your doubt :)

Hi Richard,

The Missing Arrow example has a digit missing: R1C6 is given as 7 in the original test's IB.

You are both right. It is still solvable, but considerable harder. I will adjust the IB.

Is this better: ... digits in these cells must have a value between the values of the given digits. ?

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?

Does the Sudoku XV in the IB have 2 solutions? I have a different solution and I don't see any mistakes in it.

Yes, the first puzzle has a unique solution without information from the second puzzle.

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.

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 ?
