I enjoyed Hexcells. Did quite a few of those puzzles once I found out about the Reddit board.

https://www.reddit.com/r/hexcellslevels/ has many Hexcells puzzles for free.
The normal way to play these is with Hexcells Infinite, which is in Humble Indie Bundle 17. If you did not buy the bundle, you can play for free by installing Sixcells: https://github.com/blaxpirit/sixcells#player
