About this gameFull description from Steam

Step by Step At first, each message will seem like incomprehensible gibberish - convoluted, seemingly meaningless. However, nothing could be further from the truth! By deciphering subsequent letters and words, you will quickly find a pattern that will allow you to decipher the entire message. So much to discover! Uncovering a variety of quotes rich in humor, wisdom, or insight can be challenging, yet with 100 levels to complete you are sure to have enough room to hone your skills and become the true expert. Each new message grants a sense of satisfaction and an insight into the wisdom of the brightest people in history! Nearly endless content Your decoding journey can continue almost endlessly, with Cipheur offering a rich supply of extra coded message packs. Test your wits against sets like Last Words, Proverbs, Stupid Laws, Uncommon Words and many more! All this wrapped in a pleasant, simple and concentration-friendly visual layout to help you work and relax. • 100 quotes by famous people - fun, witty or insightful - we have them all • 3 difficulty levels to allow you move forward in your own pace • Helpful hints system • Numerous achievements to unlock • An unusual gameplay focused solely on deciphering coded messages
