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. WHAT PLAYERS SAY "solid puzzle game, fantastic note taking system" (TheRedrakerbz) "gradually builds from simple to challenging and on to impossible [but not really].

Verdict
The clearest difference is in-app purchases: Gridlock at none against Dyslock's 3. Gridlock also leads on ads (none vs shown) and update cadence (fortnightly vs every 5 weeks). Dyslock's advantage is ratings volume (72 vs 4). On price, rating, review sentiment and device support there is nothing between them.
