Can you crack the code? Dyslock is a pure logic puzzle inspired by the classic Mastermind. A secret code is hidden. Each clue shows a guess and its pegs: how many symbols are in the right place, how many are in the code but in the wrong place, and how many are not in the code at all. Compare the clues, take notes, rule out the impossible, and find the only code that fits. No guessing, no luck: every puzzle is solved by deduction.

Verdict
The clearest difference is ads: CodeAB at none against Dyslock's shown. CodeAB also leads on monetization model (free vs free with in-app purchases) and rating (5.0 vs 4.8). Dyslock's advantage is ratings volume (72 vs 3) and iOS requirement (15.0 vs 17.6). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. CodeAB sells 1 one-off in-app purchase and Dyslock sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
CodeAB holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Dyslock has 72 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
CodeAB ships an update every 6 weeks, Dyslock every 5 weeks. The most recent releases landed on October 4, 2026 and October 15, 2026 respectively.
