While many great puzzle games have a fixed number of levels, I’d like to find more with procedurally-generated levels to maximize replay value. Aside from Minesweeper games, so far I’ve found the following ones:
- Hexcells Infinite
- InfiniPicross 2.0
- KNIGHTS
- Lines Infinite
- Linklight
- LOOP
Hoplite maybe? It’s on mobile but is a lot of fun.
