Location: France		Hi,

In both cases you need to be very careful about the sentence beginning like this : "If there is no..."

To be clear : on rossini sudoku, there are no arrows because, on this particular puzzle, digits are never in strictly ascending or descending order. This is a very useful information.
On tennisdoku, where there isn't a tennis ball the score can't be one of a tennis match. For example, if there is no ball touching a "4", there can't be a "6" in the adjacent cells.

Does it help you ?

! SPOILER !


Let's have a look at Rossini sudoku :

Spoiler: show

There is no arrow at the right of 5th row. This means that the 3 corresponding digits cannot be in either ascending or descending order. We already have 5>1 so the cell located between those two must contain a digit which is either smaller than 1 (impossible) or bigger than 5. This digit has to be 8...


Now look at Tennisdoku :

Spoiler: show

The 5th row is again particularly useful. 2, 6, 8 and 9 remain to be placed. There is a ball touching the 3; the only possible score with a 3 is 6-3, so let's put a 6 in R5C2.
Then : on the left edge of this cell, there is no ball. So, R5C1 and R5C2 (6) cannot form a valid score. 2, 8 and 9 remain to be placed. 2-6 would be a valid score, as well as 8-6. So, there must be a 9 in R5C1...

...in TENNISDOKU only few scores were visible (in application and in the pdf)...
Thanks Ours brun.

lucarabino: Yes. In Tennisdoku (as also in Kid sudoku), all scores were not given as clues, as then it would have become too easy. But the grid was solvable with the given clues as the tennis balls provided enough hints. And 59 solvers did solve it.
