Well interesting set of puzzles. Wasted lot of time in switching between puzzles and couldn't complete lots of them. Have to solve remaining. Thanks for the test. | ||||||||||||||||||

Typed Logic Author Posts: 241 Location: Indonesia | My first ever podium finish that I can remember, and this is done when I'm half-asleep. Clearly I should do contests while half-asleep. :P | ||||||||||||||||||

Clearly I should do contests while half-asleep. :P 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. | ||||||||||||||||||

forsmarts 13th Anniversary Contest Author Posts: 33 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.

Posts: 1 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.

Posts: 42 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. | ||||||||||||||||||

Typed Logic Author Posts: 241 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.

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. | ||||||||||||||||||

Classics & Regions (PR 2016/17) Author Posts: 170 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! rob - 2018-02-24 8:36 PM 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). Example is not unique for slalom-like solution, there's one cell that may contain either slash. | ||||||||||||||||||

Posts: 42 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! :) | ||||||||||||||||||

Posts: 11 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. | ||||||||||||||||||
