Train your brain! Try to guess the secret word before you run our of chances.

A spin on the classic word-guessing puzzle game, LetterCode challenges you to decrypt a secret code. With each guess, you’ll learn a little bit more about the code:
— Red means the letter isn’t in the answer
— Yellow means the letter is in the answer, but in the wrong place
— Green means that you have the right letter in the right place
Try to crack the code before you run out of attempts, and for an additional challenge, complete it as quickly as you can for an even higher score!

LetterCode lets you customize your gameplay:
— Hide the timer if you don’t like the pressure
— Turn on and off the sounds effects or music
— Adjust the difficulty by changing what types of inputs are allowed (but be careful, this can affect your score!)

LetterCode is limited to 5 plays per day, but you can purchase LetterCode Pro to unlock the following:
— Unlimited gameplay
— Access to “Hard” and “Expert” mode - get harder and longer words
— Access to your stats and play history

LetterCode Pro is a one-time purchase and supports family sharing.

What’s New

Version 1.1.2

- This update contains many small (but important) UI adjustments. Users on iPhones with small screens and/or Display Zoom should have a much better time. But the changes should also result in a more consistent experience across all devices. I can't always foresee every potential issue, so if you run into something, please contact me using the button in Options!
- I have updated some of the animations at the beginning and end of a game. Hopefully you like them. I think that they make the app feel more polished.
- More features are coming, but I wanted to get this bug fix out ASAP. Stay tuned!
Did you know? Whenever you update LetterCode, it resets your plays for the day! It’s just a small thank you for being a dedicated player.

This is one of the greatest word guessing games I have ever played in my long history of writing app reviews. This game really opened my eyes to the possibilities of mobile games and I play this game 24/7 I can’t stop!! Amazing work, Joseph!

Amazing game

This is a great game if you wanna challenge yourself. To me it’s better than your popular word games like word scramble, word hunt, banana grams, etc.
