What is Cryptogram: Logic Game

Every letter in the alphabet has been swapped for another—your job is to figure out which is which. Dive into a series of encrypted quotes and test your deductive reasoning.

How to Play

Click any letter in the cryptogram to open the alphabet and choose which letter you think it represents. The game fills in all instances of that symbol across the puzzle, helping you build the solution step by step.

Tips for Playing

Start by looking for one-letter words—they are almost always 'A' or 'I'.
Look for common two-letter words like 'of', 'to', or 'in' to guess letter pairs.
Check for apostrophes—the letters after them often hint at 'T', 'S', or 'D'.
Try filling in the most frequent letters first, like E, T, and A, based on frequency.
If you get stuck, clear a guess and try a different substitution to see new patterns.

Frequently Asked Questions

How do I make a guess in the game?

Click on any cipher letter, and a pop-up will let you select the plaintext letter you think it matches. The game will apply it to all matching symbols.

Can I change a wrong guess?

Yes, simply click the same cipher letter again and select a different letter. You can also use the undo or clear function to reset your guesses.

Are the puzzles different every time?

Yes, each puzzle uses a random cipher substitution, so even the same quote would have different letter mappings on each play.

What if I don't know a quote?

You don't need prior knowledge—the logic of the cipher will guide you. Use word patterns and letter frequency to solve it step by step.

Is there a hint system available?

Most versions of the game offer a hint button that reveals a correct letter for a selected symbol. Use it sparingly to keep the challenge.

Does the game support mobile devices?

Yes, the game is designed to work on touch screens, so you can play on your phone or tablet easily.
