Dec 28, 2017 at 23:44 comment added Bass Assuming there really is no clever "other solution", I'd like to suggest a slight modification: remove the middle stick in the vertical line of 5 sticks, and transform the problem into this famous one. Notice the lack of sore sticks, how the starting position is 4-way symmetric and the answer is not, and how all the squares in the starting position are non-adjacent, and the answer has squares crammed in as tight as possible.
Dec 28, 2017 at 22:02 comment added ekhumoro It also means there is no unique solution. The sore-stick solution can be formed in 16 different ways.
Dec 28, 2017 at 17:12 comment added Bass The obvious solution has 17 squares and one extra match sticking out like a sore.. stick. This is, in general, an uncool thing: all the matches should be meaningful parts of the solution. I hope there is a less obvious solution that makes use of all the matches.
