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! And don't worry, there is a colorblind mode. ---------- LetterCode lets you customize your gameplay: — Colorblind friendly! — 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.

Verdict

The call

The clearest difference is ads: LetterCode at none against Pixel Stacker's shown. Pixel Stacker's advantage is update cadence (weekly vs fortnightly) and iOS requirement (11.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.
