If you like logic #puzzles I recommend "Loopy" from Simon Tatham's Puzzle Collection.

Iʼm more into Net, but nice puzzle collection indeed!
@hexmasteen Love this collection of puzzles :) Trying out, then figuring out and getting better at different kinds of games was a pretty unique experience, spent very many hours with these.
