In general, many of the answer keys seem trickier than necessary -- really, counting the C's? diagonals that go in the opposite of the usual direction? --, but it's too late to change them.
I'm a pronounced left-handed. Maybe because I offered unusual diagonals? |

2. Ogranichenij net: v belyh kletkah mogut vstretit'sja ljubye cifry, v tom chisle 2 i 5. |

2 zerkal'no otrazhaetsja v 5, esli rech' o sosednih po gorizontali ili vertali poljah. V sebja 2 otrazhaetsja "tol'ko po diagonali".
S 3 vsjo verno. |

I am not able to solve even a single puzzle :(
Read the rules carefully, multiple times.
Try to find openings, applying the rules.
Try to think "If .... then what happens, is any rule violated."
And if you are stuck, save your work and come back later.

Location: The Netherlands | I have a little question about puzzle 10...
In the requested sentence there are two "I' 's and one time the digit 1. But it looks like there are three same characters "I" (or 1?) in the grid? Could all three characters be used for the digit 1? |

1 can be any of the three "I". Two other "I" will be letters. |

Location: France | Just to make sure -- in "Tools", the answer key only describes whether the edges of the grid along the given row or column are occupied (and if so by what tool) or not, correct?
More precisely: what would be the answer key for the second row in the example? Am I right that it would be -----HH---- ? (i.e. the edges that are "inside" the ladder are unoccupied and so remain "-" in the answer key, even though there is a ladder) ?

Yes, for the second row in the example the answer is recorded correctly. |

Location: New Zealand | Just a small confirmation for #10 (April Contest 2015 At LMI):
At the points of intersection, the line path must always continue straight ahead, it cannot have 2 turns (reflecting off each other)? |

Like every year, we have prepared images for optimizer submissions. Couple of notes
1. In Puzzle 10 (LMI Contest 2015 at LMI ) we had to manually determine the end point of the line in several cases. Please check if your submission is different than what is intended.
2. Riad is still solving all the Puzzle 12 (ROMAN COOL-L-L ) submissions. If you notice any grid is invalid, please post here.

Location: New Zealand | Player3 grid has 8 solutions. It has six rows of "LOOLOOLOO", and 3 rows of "CLLCLLCL?", where "?" can be C or L. |

Location: India | Thanks James. What about Player13? |

Location: New Zealand | The Player13 grid is interesting.
The only way to get four adjacent 200s is with:
LOLOOLOOL
OOLLLOOLO
OLOOLLLOO
LOOLOOLOL
or its mirror image. (this is not simple to prove!)
So that fixes the top 4 rows, and if the bottom 4 are the same pattern then the solution must be:
LOLOOLOOL
OOLLLOOLO
OLOOLLLOO
LOOLOOLOL
LCLLCLLCL
LOLOOLOOL
OOLLLOOLO
OLOOLLLOO
LOOLOOLOL
If the mirror image option is used below then no solution is possible.
So the Player13 grid is fine.
