Can't see any point in leaving outer half as it'll make the puzzle no different to a usual Snake. So the answer would be "no". tamz29 - 2018-02-15 12:52 AM 5. Triangular Battleships "Numbers outside the grid indicate to product of all lengths occupied by the ships in the corresponding rows/columns." I don't understand this. For example, there's two segments occupied by the ships in a row: 1/2 and 3/2 (1+1/2). Then the clue outside would be: 1/2*3/2=3/4. tamz29 - 2018-02-15 12:52 AM 10. Unknown Calendar "Each pair of consecutive numbers should have at least one digit in common and has to be placed in either same row or same column of the bottom table" Is this two requirements or just one needed to be satisfied? In the example, you have 29 and 18 in the same column, can they be consecutive in the puzzle grid? "For example, 15 can be followed by 11 or 25, but not by 10 (different rows) or 17 (difference is less than 4)." But there is no 10 in the table. There might be in an actual puzzle. tamz29 - 2018-02-15 12:52 AM 11. Unknown Diginet Can the lines be diagonal? As long as they connect the numbers, they can go whatever direction you wish. | ||||||||||||||||||

What is a turn defined here? For e.g. R3c1 to R2c1 is it defined as turn? The picture shows how the snake looked like before the corners were cut off. I hope now it's clearer. | ||||||||||||||||||

I'm not sure I understand the question. If you're asking whether the inserted digit can be a start for a new line then the answer is "no". The lines should connect the originally given numbers only. | ||||||||||||||||||

A good mix of puzzles -- with a mix of quality, too. But most puzzles are good. Let's see: - Non-Integer Kakuro: This is just Missing Digits Kakuro (or something like that). The non-integer part isn't utilized much. And honestly I don't think you can do much with Non-Integer Kakuro that you can't do with Kakuro with nonstandard set. - Non-Integer Kropki: You can just multiply by 2 to get normal Kropki except white circles have difference 2. But at least this one changes the meaning of the circles, and so is a more interesting application. - Cornerless Snake: This is actually a very interesting design, even if I ended up intuiting it. Still need to figure out a more logical approach, but this puzzle was good. Answer key was less good though; I'm not sure if H, F, - make the best answers, but I feel like it could have been better. - Triangular Minesweepers: Both puzzles were incredible, although I think the large one ended up needing a few "I think this must go this way" reasoning near the end. Very good showcase of these puzzles. Answer key was... weird; could have gone with all letters (Mine / Empty, for example), or something that involves orientations of the mines too. - Triangular Battleships: I also mostly intuited it, but I think it has a nice logical solution. And even though its name is Battleships, its logic has nearly nothing in common with it. - Incorrect Easy As ABC: Somehow this one doesn't seem quite penetrable and I had to resort to guessing a lot. My first opinion is that this type is kinda brute-forcy, but if someone can show a logical solution... - Incorrect Products: This one, though, is way fairer. I identified the two conflicting clues right away. These liar puzzles seem to be best if there's a clear set of contradicting clues, which I don't believe I find in Easy As ABC. - Incorrect Calcudoku: Same as above, although the contradicting clues aren't as clear. But still very reasonable. - Incorrect Spiral Galaxies: Ehhh, I intuited this through like usual Spiral Galaxies. I'm sure it's possible to do it logically, but most Spiral Galaxies fall through with intuition easier. - Unknown Calendar: Oops I skipped this. But "sharing a digit" and "in the same row/column" are two different things and the instructions should have exactly stated which one. At the current state, 2 and 10 may or may not be adjacent. - Unknown Diginet: Okay this is an incredibly weird genre and I'm not sure whether I like it or not. I ended up intuiting it and I'm not sure what logical solution I can possibly obtain from this genre. The answer key is also not something I'm sure I like. - Unknown Pentomino: This one falls through fairly, and nothing particularly notable. - Instructionless Alpha: This is a pretty good genre idea, although the logic falls through very easily once you get the tricks. Answer key was a big mess though; should have gone with the same symbols instead of translating to B and F. - Instructionless Beta: Oops I still can't figure this out. - Instructionless Gamma: Region borders might have been better clearer, but otherwise this lends itself to easy puzzles. Not certain the answer key was the best (could have gone with the standard "longest/all segments in marked rows/columns"). So, all in all: interesting puzzles, some less-than-perfect applications but mostly good, some less-than-perfect answer keys as well, but I enjoyed the interesting genres. | ||||||||||||||||||

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

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