What is Decodex?

Decodex is a daily cryptography puzzle that challenges players to decrypt an encoded quote by guessing the correct letter for each character. The game provides the author of the quote as a starting hint, and players can unlock additional letters using available helps. Each day brings a new puzzle, and the game is won when every encoded character has been correctly replaced with its true letter.

How to play Decodex

To play, select an encoded character and use your keyboard to guess the letter you think it represents. The game tracks your time and offers a surrender option if you get stuck. A hint at the top of the screen shows the quote's author to give context. The game is updated daily with a fresh puzzle.
