Do yourself a favor, if you haven't yet: go in the instructions for the games you like and find out the original game's name (for example' "Light Up" is actually called Akari), go online and find hand-crafted puzzles for that game. I love that Simon Tatham's Puzzles exists, but nothing beats hand-crafted puzzles made by good designers. There's a sense of purpose in the order you discover the solution and some "eureka!" moments that randomly generated puzzles will never give you!
