There are sites such as [ http://www.herrmann.me.uk/script/puzzles.htm ] which offer help with solving Suko and Sujiko puzzles, along with Master Sujiko. I’ve not offered such a facility myself for two reasons – 1. Because others can build this kind of programming better than I can, and 2. I think it takes away from the challenge when the solution is only a click away! Still, as they say, different strokes for different folks! I must say that your working method on this puzzle is very much the same as mine [ I work through each puzzle manually when creating them, to ensure that they can be played by humans, as well as machines ðŸ™‚ ]. I’m chuffed to see people still playing, and enjoying my puzzles, so thank you for that.

Wed, 14 Sep 2016 09:14:40 +0000http://blog.ifem.co.uk/suko/#comment-7535It’s easier to use simple logic. Middle square must be 1 to make higher 18 total. Three of the white squares plus left-hand red square make 23, but same three white squares plus top left square make 16. Hence left-hand red square must be 7 greater than top left square. We’ve already used the 1 so it must be 2 and 9. Then the other red square must be 3, and we can put in 5 to complete the lower 18 group. The middle and right hand squares on the top row must total 12. Only possibility left is 4 and 8. 4 must be on the left or you get a duplicate 2 in the 13 group. Then 6 and 7 go in easily to complete the puzzle. It’s a lot quicker to do this than to write it!
