Puzzle 4: Fillomino (no row/column repeats)
This is a Fillomino with a slight twist. Instead of no two regions of the same size touching, in this puzzle, no two regions of the same size may even be in the same row or column. In other words, if two 5’s, say, appear in the same row or column, then they need to be part of the same region.
Notes: I made up this (probably not original) variation and subsequent puzzle yesterday (thanks to my study hall-mate matt for testing!). The new rules can make for some slightly interesting deductions, but they’re not as flexible. Anyways, I hope you like the theme, and if you can come up with a concise name for the variation, please say so. 😀
