Puzzle set: Polish qualifiers 2016

I made a couple of puzzles for the Polish qualifiers back in February. I previously posted two more puzzles which didn’t make it: Angle Loop, Doubleback.

One Minesweeper puzzle (with an unknown number of mines). The kind of puzzle that just feels too trivial when constructing, although in the end I think it’s quite ok.


One Pentominous, with the obvious PL theme.


Finally a small an tricky Checkered Fillomino.


Puzzle 2: Checkered Fillomino

This variation was introduced by Nikolai Beluhov at Puzzled by Titles, see the authoritative rules and two very tricky puzzles: Fillomino 6: CheckeredFillomino 8: Checkered. Here’s something that’s hopefully both correct and a little more approachable.

Rules (brief): Solve as a standard Fillomino, and shade some resulting polyominoes, such that no two shaded or unshaded polyominoes share an edge.
