The reason it is specified for Round2 is because I had to explain the partial points. Otherwise I wouldn't have mentioned that.
I can do that for Round1/3, but will it be really useful for you in planning / making a strategy, I'll do that. let me know.

Location: India | Oh wait... may be I can't.
Many participants don't read forum, and it will be unfair to publish something about the puzzles here.
Sorry.
As such, if we publish the grid sizes beforehand, it will probably be first of its kind. |

Location: India | Since, i am new to puzzles, wanted to pick and choose which to concentrate on , like points grid size also indicate the complexity of a puzzle,
The grid sizes /range in some cases are surely useful, frameless sudoku, different sums, where combinations are needed
Also if posting in forum is a concern, updated IB is as an option ,open to other view points, |
| |
|
Location: India | I must be sleeping when I wrote that we can't publish here. Obviously, as you said, we can update the IB
Utkaarsh, let me emphasize that the grid size will not reveal anything about puzzle complexity. As a sample, if I say the Frameless sudoku is 9X9, it doesn't signify anything about its complexity. It is only points that tell you more about difficulty.
For players who are new to puzzles, it is important to form a strategy to solve the types you are more comfortable with, irrespective of the grid size or points. |

is it like minimum possible bulbs? Come on Swaroop, it is a standard puzzle, with standard instructions. I've no idea why you are confused. |

Location: United States | Hey everyone. Today on The Griddle I posted a new puzzle that may serve as good practice for the masyu-fence puzzle:
Shotgun Slitherlink
In this variation there's one additional twist: all the numeric clues consist of a 2 directly to the left of a 3, to form several instances of "23" throughout the grid. Every place that a 23 can legally be placed in the grid, the clues are given.
I also have additional masyu-fence puzzles (that I call "shotgun slitherlink") on my site which you can find here.
Happy puzzling!

Location: India | Any particular reason puzzles of Round 2 are 20x20? I understand the concept is big grids, but was 20 chosen as a random round figure or does it have any significance? Just for trivia sake... |

One rule I wanted to confirm that, can the ending square be in the middle or it should always be touching a wall?
e.g. attaching the puzzles from Brazil Puzzle Championship where ending square is not touching the wall or black square.
See the following answer booklet

Location: India | okay..is this solution possible for the given 'tiger in the woods' example given in the IB ? |

Location: India | I think the players want to know if the ending cell can be 'anywhere'. There can be another solution then.

Location: India | This is not allowed. The path can stop only near the wall or a black square.
Also, the end point must not have visited earlier.

Look at all rows and coloumns with A and B as clues.....
means R1, R2, C2, C4
C cannot be placed in 1 and last cells of these rows and columns...
with this C cannot be placed in R1C1, R1C4, R2C1, R2C4 therefore in first two rows C has to be in second and third column.
Again with the same logic C cannot be placed at R1C2, thus place C at R1C3 & R2C2.....
Now its simple.
