Location: India | Its time for some practice puzzles. I have made a Nurikabe loop here - http://prasannaseshadri.wordpress.com/2012/08/12/puzzle-no-192-nuri... and I've also linked in the post to one I made earlier before I had any clue that this type already existed.
Also, there is a Skyscraper Rising that can be found here - http://sugarroad.blogspot.jp/2012/08/puzzle-036-skyscrapers-rising....

Location: India | From every number,keep following the arrows until one of the grid edges is reached.You cannot skip an arrow in your way,which means all arrows are functional unless they are not obstructing your path.The significace of the number is,your path cannot reach the edge using fewer (or more)than that many arrows. |

Can the Signage rules be explained a bit more. Esp para 2.
Look for example at the Arrow with the 5 in R4C3.
1) The path starts with the arrow up in R5C2. Going up the next arrow you encounter is in R2C3.
2) The arrow in R2C3 points left. Going left the next arrow you encounter is in R2C2.
3) The arrow in R2C2 points down. Going down the next arrow you encounter is in R5C2.
4) The arrow in R5C2 points right. Going right the next arrow you encounter is in R5C3.
5) The arrow in R5C3 point down. Going down you don't encounter any arrows anymore and the path leaves the grid.
So you've followed the direction of 5 arrows till the path leaves the grid. This is what the clue number in R4C3 indicates. |

Location: India | Interestingly,I wrote a rising skyscrapers variation in late 2007, only that, it asked for the digits along grey lines to also be strictly consecutive, and not just increasing.That was perhaps a little more constrained,but it depends on how the design works.I made one with the same rules as in the LMI booklet.I think the lines interact nicely with the skscraper logic here. Also posted the one that follows the rules of my version.You can see both at - http://anuragthefirst.blogspot.in/2012/08/rising-skyscrapers.html

IMO, the puzzle is finally correct with a unique solution, so added back the link. |

Location: Japan | So many innovative puzzles... I'm really looking forward to the actual test!
BTW, let me confirm one thing about Chained Ships; is it possible to place a ship segment on a letter?
(even if two As are covered by ship segments, the grid might be solved by connecting other letters)

Location: Turkey | Some Remarks
Puzzle 1: 3rd rule of the puzzle transform to "Each area should contain exactly one number"
Puzzle 5: Write the 3 unused words , and ignore the Turkish letters when submitting answer.
Puzzle 9: Write the 3 unused words , and ignore the Turkish letters when submitting answer.
Time Bonus: I've changed the percentage (previous one %95) because of puzzle difficulty, so If a puzzler can get %90 of 1600 points (Total points), he/she will earn time bonus as 0,05 points per saved second.
Points distribution is available below.

Location: India | When you say ignore the turkish letter, do you mean "ÇÖZÜM" becomes "ZM" or "COZUM" or something else?Any information on how many words will be used will be given,or is it part of the solve?

I mean that "ÇÖZÜM" should be "COZUM" when you submit. |

Location: India | I was looking at the example for signage in IB. Can anyone share a couple of starting steps? Except the clues on the edge, where arrows obviously cannot go towards the edge, I am unable to make much of a logical headway. |
