I was able to answer both Alphas without finishing the puzzle, due to the answer keys pointing to easy rows. Not sure why rightmost lines were used, leftmost feels more 'normal'. Alpha Small felt like it had 2 solutions? Don't like the Beta example. I solved the first two as integer puzzles, which I think is a nicer presentation. Gamma, Unknown Pentomino, and Alpha were my favourite new types. | ||||||||||||||||||

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

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

Posts: 1 Country : Poland | skrzypl1 posted @ 2018-02-21 3:43 PM 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. Edited by skrzypl1 2018-02-21 4:04 PM | ||||||||||||||||||

Posts: 42 Country : United States | Ziti posted @ 2018-02-22 10:22 AM 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. | ||||||||||||||||||

Posts: 241 Country : Indonesia | chaotic_iak posted @ 2018-02-23 6:55 AM 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. | ||||||||||||||||||

Posts: 170 Country : Germany | rob posted @ 2018-02-24 8:36 PM 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. |
