In Arrow Connection if an arrow appears twice around a cell, is an arrow given twice or once. I know it's not possible in the example as the start and goal are in the corners, but with different start and goal points, this could happen. For example, when you draw a spiral.
Good question. An arrow is given only once even in such cases. |

Location: India | In Divided sum cross it says " no digit repeat within a single group divided by black cells".
so if clue is 7:_ _ _ _ _ :17 (5 cells blank in between). so is all 5 cells considered one group or is considered as two groups ?

All 5 cells are considered as one group. So, solutions like 7:1 6 | 4 7 6 :17 (two 6's in one group) are not allowed. |

Clearly I should have done the practice first.

I couldn't find elegant way to solve Yin-Yang top. (ToT)
My favorites were Number connection bottom and Four winds with blanks bottom.

Hello Ko (and others),
Please see my diagram.
I have put all the 'easy' logic in first.
Then I see the two red rectangles have the form:
B.B
B.W
which must become:
B.B
BWW
Later, I use the same rule in the green rectangles.
I think that is enough to finish.

Location: Estonia | I actually think that there were exactly right amount of puzzles, because of the amount of top solvers who were able to complete this competition within the time limit. There were just too many puzzles for me, but I think it's not bad (I would paint it green if I could). Anyway the puzzles were very interesting to solve, thanks to the authors!

A delightful test!The moment i saw the puzzle types in the IB I knew that this puzzle test had something in it for me and was going to be one very interesting test.Certaintly the test far exceeded my expectations.My favourites out of the puzzles i have solved until now are Four winds 2 which had a very high fun level and utilised the following concept : 'a particular cell where no number can reach' exceptionally well
,Sky-scrapers 2 which had a very beautiful logic quite similar to the one i encountered in a recent daily league sudoku,Divided sum cross 2
My only disppointment is that i was unable to complete the Divided sum cross 2 despite starting it with close to 30 minutes on the clock.The puzzle was proceeding very smoothly for about 20 minutes until the point where for some mysterious reason ,my brain mis-interpreted the upward sum 13 clue to be a rightward clue which forced me to enter a 1 in addition to the 7 and 5 already present .The puzzle
never broke until i was about to write the numbers in the last 2 cells!!!Unfortunately i had no time to notice where i had made the error let alone fix it.But this did not come even close to disrupting the good fun i had in solving the test.
Thanks to all the Japanese authors for creating meticulously such beautiful hand-made puzzles.This test indeed deserves the tag of being one of the best LMI puzzle tests.Lastly ,is that some Yin Yang theorem going on above in the forum?!Why can't it be a BWB??? |
