    8 mins 12 s ….went wrong once in the middle due to over speeding..
    Then erased again fully and then did..I need to maintain a fine balance between flow ,speed and doing correctly which i am not doing..

    I wasn’t timing very well, but I think it took me about 5, maybe a bit more. I like how the middle flows and the logic at the bottom.

    Been trying to do something with the hashtag – which itself has no solution. How did you manage to find the placement of the other consecutives – with just two solutions?

      At first I couldn’t parse this comment. Then I realized you might be trying to make other consecutive puzzles with just these shapes.

      Indeed, just the Hashtag has no solutions. I forced the internal shape, and the lack of any connections in a one cell outer ring (rows 2,8, columns 2,8) and then there were a bunch of solutions that add extraneous bars to the far outside. I picked one that seemed to solve well. Making “pretty” consecutive puzzles is very hard and having some flexible tools that allow an “either/or” set of positions to assist my usual process has always been necessary. A lot more could be done visually if the “if and only if” rule was dropped, but that probably makes the solving much less fun.

  • HATMAN says:

    I’d managed to work out how to do it, but as you say very time consuming to get something reasonable.
