Enjoy the relaxing puzzle-solving experience of Countless Calming Cryptograms. Cryptograms are simple substitution-code puzzles in which each letter in a quote is substituted for a different, random letter. The object is to use your logic to decipher the code and reveal the hidden quote. Look for common, simple words like 'A', 'I', and 'THE', and decode the puzzle letter by letter. Like crosswords and word searches, cryptograms are excellent word games to train your logic and puzzle-solving skills, and to give your brain a workout to keep it strong. Play the Daily puzzle for your daily inspiration, and share it with your friends! Then play the tens of thousands of word games available in Countless mode, for endless motivation and serenity. Get unlimited hints to make the word games easier! Win Lotus Points as you play, and use them to reveal letters or skip puzzles as you wish. You can always watch an ad to win more Lotus Points without having to solve a puzzle. Or skip the hints altogether if you like a challenge. Take a spa day for your mind. Countless Calming Cryptograms is designed to be a relaxing word game experience, with calming and serene landscapes to enjoy while you solve the nearly endless puzzles. There are tons of customization options available, including beautiful landscape backgrounds, color themes, day/night mode, and gameplay settings. It's easy to change the font size if you prefer it bigger or smaller. You can also play offline, making it easy to play while you're traveling or on the go. Take a break with word games in a beautiful environment, and keep your mind sharp all at once. Keep calm and cryptogram on!
