Snowmen Author Posts: 44 Location: Russia | Summed snake--all the "fun" of trial and error combined with lots of arithmetic? For my opinion summed was most logical puzzles in this contest. | ||||||||||||||||||||

Posts: 16 Location: United Kingdom | I'm feeling a tiny bit hard done by because I started the contest, the site crashed almost immediately (as I was entering my first answer) and didn't come back until long after my 90 minutes were up. No worries really; I'm rubbish at Snake puzzles anyway. | ||||||||||||||||||||

Nice puzzles anyway!! Interesting. If my printer had issues I'd just do this on MS Paint. In fact, I was debating with myself about solving this round on paint because I actually thought I'd be faster, but then I thought solving on paper will help me more with offline competitions and went with that. Still, I personally think Snake is a puzzle which can be done with the fill option on paint. The only variant from the contest for which I'd say its better on paper is Summed Snake. Our notations while solving the puzzle probably differ though. | ||||||||||||||||||||

Posts: 5 Location: India | Taking basic snakes puzzle , when there are numbers outside the box, say 5 , what I generally do is find combinations : 2+3/ 3+2, 4+1/1+4 and find similar combinations with other rows/columns and with trial and error fit it in. Is there any other logical way to work around? Maybe knowing this will help me with other puzzles too. | ||||||||||||||||||||

Is there any other logical way to work around? Maybe knowing this will help me with other puzzles too. Yes, there are quite a few ways or few places to look for. For classic snakes, 1) Look where the head of snake can move 2) Look where the tail of snake can move 3) Look for Big number clues 4) Look for group of clues together in adjacent rows. Of course most of solvers , visualize an rough sketch of path as well. But for this contest at least, you don't need that, it moves logically all puzzles. But in generally knowing these techniques is not enough, but applying it. So in particular if you face any issues for any puzzle, post that and puzzlers here will help you through solving it. | ||||||||||||||||||||

Posts: 11 Location: Japan | In this test, I think toroidal snake is most difficult. In particular I couldn't find even the first step of two puzzles on page 6. Anyone knows how to start? | ||||||||||||||||||||

Anyone knows how to start? We are planning to document steps for as many puzzles in this contest, but that will take a while. In the mean time, here are the steps for Toroidal - 3(9X9) (Logic and images from Prasanna)

Our notations while solving the puzzle probably differ though. I did the first couple of classics in Paint while I waited for the printer to print (which is why I had a wrong submission, I didn't colour in the first tail cell specifically and thought it was empty when entering the answer key...!) But I think all of Horse, Toroidal and Summed benefit from extra notation (Toroidal especially, I like to replicate the cells on the far sides of the grid to better visualize what the snake is doing) so decided that paper solving was best. | ||||||||||||||||||||

Ah, I forgot about Toroidal. I'm generally just good with those without replicating the cells, and it was the same here. | ||||||||||||||||||||

Location: India | Steps for Snake - 1 1. The snake has not go up from R7C5, otherwise the 6 clue of row 6 can not be satisfied. 2. At R6C5, the snake has to turn right. | ||||||||||||||||||||

Location: India | Steps for Snake - 2 If the snake passes through R3C1, that end will meet R2C3. No further snake parts are possible in the right side region, so the 3s of R2/3/4 can not be satisfied. | ||||||||||||||||||||
