A big milestone for me has to be Puzzle Fusion, which was held during the early days of LMI back in the end of 2011. I still remember the frustration of tossing piles and piles of scrambled-up grid paper until every corner of my room was slowly drowning in litter. I completely underestimated how hard it would be to write this 24-puzzle test.
The concept was two puzzle types combining to get a hybrid type. There were 8 sets of combinations and most of the solvers’ ratings were for the hybrids. The first hybrid was Kropkuro. Please correct me if I’m wrong, but I believe this was Kropkuro’s first appearance –before it started popping up in several European tests and most recently in Matus Deminger’s Kakuro contest.
I was still new to constructing and Puzzle Fusion ended up with a really poor balance of difficulty-spread among the puzzles. The Kropkuro ended up being too massive for such a test but as a stand-alone, I’m sure it is still enjoyable to solve.
Go get it!
Kropkuro – Fill in the grid with numbers 1-9 so that each number adds up to the given sum for that row or column. No number may repeat within a single entry. A white dot is given when the two neighbouring cells contain consecutive digits. A black dot separates two numbers where one is twice the other. 1 and 2 may be separated by any coloured dot. All dots are given.
