In the Doppleblock puzzles just checking if two darkened blocks can be adjacent - in those rows and columns where the sum is NOT given on the edge.

Not necessarily. Other clues may in some cases force the darkened blocks to be adjacent.

Round 4 of Puzzle Ramayan 2016/17 is over. Congratulations to top three solvers Kota, Hideaki and Nikola, as well as Indian top three solvers Rajesh, Rohan and Swaroop.

LMI website has always been a corner I visit at least once every day. I enjoyed too many contests on this website. I am happy to prepare a puzzle round here and I hope you all enjoyed while solving this round.

Hashi and doppelblock sets are the two sets most solvers liked, as I can see in this forum thread. I prepared some doppelblock puzzles previously, but those were the first hashi puzzles I ever prepared. :)

I thank to Serkan and Kamer for test solving. Also, thanks to LMI for giving me this opportunity of preparing a puzzle contest and also for helping in the preparation of the contest.

When will the answer key be released?
