I've come to a similar conclusion recently. I make more mistakes when I'm solving fresh -_- There's probably a weird theory explaining it somewhere even if I can't think of one now.  |

Location: Belarus | Big thanks to all the competitors and congratulations to Endo, Ivan and Kota, who made it to a top-3.
I would also like to thank my co-authors:
Olga Shut, who created all Unknown puzzles and Instructionless Gamma
and Andrey Bogdanov, author of all Triangular puzzles.

Location: Poland | I think that Unknown digits have second possible solution: 1234. Connecting: 1-6, 2-7, 3-5, 3-9, 4-5. Am I wrong?
Also, can we know rules for instructionless puzzles? For example when I solve alpha I get multiple solutions (but proper answer keys nevertheless).
EDIT: I just figured out proper alpha rules that don't give multiple solutions.

Seems like you're right :( Confirmed with Olga.
I'll ask an administrator to give full points for this one as well. |

Location: United States | Thank you Vladimir and all your helpers for an entertaining and challenging set of puzzles. I never know how such creative people come up with new puzzle types but I am grateful that you do!
Will there be a solution pdf published? Man oh man I do not see what I did wrong on Gamma -- at least the first one seems like it follows a perfectly unique set of rules. |

Location: Indonesia | Para: The 6 is replaced by a 18; that's not a change of one digit.
And to the puzzle: It's a shame to know that Unknown Diginet has multiple solutions. That must be why I was wondering how you can possibly approach this logically.

Ah, okay. I didn’t really read the rules carefully enough. I just went with, they all work the same as the first, which was one incorrect clue. |

Location: Germany | For beta, also the line has to turn at each dot? Otherwise the example seems not unique.
The alpha rules are nice, unfortunately some Slalom-like rules were too promising for me (no loops, then no crosses: seemed to work fine for the example and the first puzzle, but the second one is contradictory quite late). |

You're right, it should also make a turn at each dot!

Example is not unique for slalom-like solution, there's one cell that may contain either slash. |

Location: United States | Thank you for the solutions, Vladimir. I solved Gamma as "Path must alternate going through circle-wall-circle-wall..." but did not realize the additional constraint. It solved the example uniquely but obviously not uniquely for the puzzles themselves. Which might explain why I had to guess and was happy (at the time!) to reach a conclusion! :) |

Location: United States | I thought it was a great contest. I did have one question about the incorrect products puzzle. I got an answer of 45213 and 23541 doing this the 36 was the incorrect product. Maybe I am missing something but after checking many times this seems to be a possible alternative solution. |

The rules say there's just one incorrect digit. If you have a solution with 36 turning into, say, 16 or 35, please share, but I still think the solution is unique. |
