Strong +1 to Simon Tatham's puzzle collection. One note: the main iOS app is a little wonky in places. I've been using Kyle Swarmer's "Puzzles Reloaded" app, which is a little nicer in places.

Yeah, this collection is _awesome_. I'm currently enjoying the Towers (just do it on 5x5 simple, and find it quite relaxing!).

Mine is currently Net, 7x7 grid with wrapping variant. I take about 5 minutes on average to solve a level, which is the sweet spot for me

I install Simon's collection on every device of mine, as well as PySol.

(I'm stuck on Guess aka Mastermind right now, and damn good at it if I say so myself! Also Solo aka Sudoku on 6 sub-blocks, with X+Jigsaw+Killer & No symmetry+Unreasonable difficulty.)

This one is so good. Original puzzles, works fine on mobile. Very future proof.

My favorite is pearl.
