Country : The Netherlands | Richard posted @ 2013-12-08 1:16 AM 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.

Could anyone explain between sudoku ? Not being able to understand
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 : ) |

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. ? |

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. Edited by Realshaggy 2013-12-13 3:22 PM

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 ) |

can anyone explain me Rules of Greater or lesser sudoku ? 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.

Country : India | 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
