So there are no playoffs/eliminators/semis/finals,right?
The total score from all the 38 puzzles across the 3 rounds will be taken into consideration,right?

That is correct.
Time bonus will be added to score.

ABC Connection: Do all cells have to be used, or can some cells remain empty?

Paint-By-Number: Are the clues in the same order as seen from the given direction?

ABC Connection - You don't need to know if all cells have to be used to solve the puzzle

Paint-By-Number - Yes, clues are in order. Will change the instruction.

Hi,
In the Queens Park puzzle it is mentioned that "A queen does not block another queen."
Then in that case R2C4 = 4 instead of 3, R2C5 = 5 instead of 4 and R4C4 = 3 instead of 2
I think it should rather say "A queen blocks another queen".

Please verify this.

Thanks
Ravi.

Sorry about that statement "A queen does not block another queen".
It is not necessary, and moreover confusing.

The correct instruction will read
"Place X number of queens into the grid
so that none of them stands on
a number and each number
equals to the number of
directions from which the given
square is attacked by a queen.
A queen attacks to arbitrary
distance horizontally, vertically
and diagonally.
"

It is important to note that the number represents number of directions from which it can be attacked.
It doesn't represent number of queens that can attack the square.

Hope it is clear.

Here is one more example of Queen

Check the 2 at R4C4, it is attacked from 2 directions (doesn't matter how many queens)

In Hexa Seven, it says 'Write numbers between 1 and 7 into the white hexagons so that the neighbours of each white hexagon are all different.'
I think 'Something Is Missing' ;-) (I guess numbers cannot repeat along any line?)

5 is repeated across the main horizontal line in the example.

2)Different Sums
sums by coincidence are 0,1,2,3,4,5,6.
but is it always true or there may be a gap in bigger puzzles like 0,1,2,5,......
3)Tiger in the woods

Swaroop, I guess in the IB example, the path starts from the circle and not from the other end.

Swaroop, the path starts at R3C1 as Tejal mentioned. Also the boundary wall is missing from the image, if that is your point.
Here is the redrawn image

Note that in the championship it is not necessary to mark the start or end. If the path correctly is drawn, you will get full points.

1)FOUR SNAILS
i think it can have multiple solutions...
the N of newyork is possible at r5c1,r4c1 and r6c1.
also the N and S of athens can be placed in r4c4,r4c5,r4c6,r5c5,r5c6 differently..

2)NEWS

in the solution it is given wrong and i am not getting proper solution..
in r2c3 it is W and r1c4 it is E but the rule says " directions in region should satisfy their positions with respect to each other"..
please clarify it..??

I think you are missing the given "-"
There are dashes at R5C1 R5C5
You can't put a letter where dash is already present

Swaroop, in "NEWS"... For W-E, it need not necessarily be in the same row. In a specific region, if you are to place W-E, just make sure W is on the left hand-side and E on the right hand-side. It may or may not be in the same row. Similarly, if you see R2C4 and R3C5, N-S they are not placed in the same column.

I hope that answers your doubt.

I think you are missing the given "-" There are dashes at R5C1 R5C5 You can't put a letter where dash is already present

In a specific region, if you are to place W-E, just make sure W is on the left hand-side and E on the right hand-side. It may or may not be in the same row. Similarly, if you see R2C4 and R3C5, N-S they are not placed in the same column. I hope that answers your doubt.
