This game draws from classic literature archived as part of Project Gutenberg to present a giant list of 432 fun substitution cipher puzzles. Spread across a range of eight genres, the chosen passages are nice little tastes of each book, and if you like what you see, the game will link you straight to a free eBook version.

There is no real twist on the gameplay concept, just a clean and easy-to-use interface for inputting the letters to fill in the hidden phrase. I prefer to play with no given letters at the start and use outside tools like a dictionary app, but there are varying difficulties available that provide a few filled-in parts to start with, and a hint system that will fill in another letter if you need it.

I do wish they offered the ability to pencil in a few possible letters in the corners of a square, like you can do in Sudoku games. Particularly when starting with nothing, it would help a lot, but the puzzles are short enough that it's not a big burden to not have that kind of feature. More context-based hints also would have been better for literature fans, I think, than just filling in a random letter.

While this is nothing groundbreaking, it's an enjoyable game that I like to pick up and play for a short time to unwind or while eating or whatever. I'm admittedly a bit skeptical that the tiny passages offered here will actually convince many people to read the books they're quoting—but maybe you can come away from this reminded of an old favorite, or feeling like 0.1% more cultured at least.
