Crack the Hidden Code - One Quote at a Time


Try a new quote puzzle every time you play - quick, challenging, and fun.

In this classic brain game, each letter of the alphabet is secretly assigned a number. A famous quote appears on the screen — but most letters are hidden. Only a few letter-number pairs are revealed. Your mission: decode the full quote using logic, deduction, and pattern recognition. The more you play, the more challenging it gets - and it’s a great workout for your brain.

How the Cryptogram Game Works:

  • Each letter A–Z is randomly mapped to a number (1–26)
  • A real quote is displayed with only a few coded letters revealed
  • Use the clues to figure out which numbers map to which letters
  • Type in your guesses to decode the full quote
  • You can make up to 2 mistakes before the puzzle resets
  • Difficulty increases as you progress - fewer letters are revealed in later games

  • Trains short-term memory and symbol recognition
