CodeLock — Zarython

Your grandfather left you a letter, four vaults, and a road nobody finished. In CodeLock you crack codes to open vaults, and every vault gives up a scrap of his letter. As the letter comes together, you learn what he spent his life looking for — and why seven generations before him died without reaching it. ◆ How it plays The code is a run of digits, none repeated. Enter a guess and the vault tells you exactly two things: how many digits are right and in the right place, and how many are right but in the wrong place. The rest is your mind. It feels simple on stage one. By stage sixty you are drawing a grid on paper. ◆ Four eras • The Last Drawer — a painted home safe, and your grandfather's study as he left it • Under the Sand — a desert excavation, and a stone door unopened for thousands of years • The Only Survivor — a sea chest eaten by salt, where the story began • Before Words — a grooved stone disc, the oldest lock humankind has known At the end of every chapter waits a lock your grandfather wrote himself, not a machine. You do not open it by guessing, but with what you learned from his papers. ◆ What you will find • 90 stages, from four digits up to seven • Scraps of a letter, collected stage after stage • Evidence that piles up in your hands — and you have to know which piece fits where • One daily challenge shared by every player in the world, its code derived from the day's date • A monthly gift calendar, achievements, and statistics that tell you how much you have really improved • Tools bought with what you earn: a hint, reveal a digit, rule out a digit ◆ What you will not find No ads. No in-app purchases. No account, no sign-in. No internet needed — the whole game plays offline. Coins and gems are earned by playing and never bought with money, because a game about opening locks with your mind should not open for cash. ◆ In your language Arabic · English · German — written and designed for each, not machine-translated. ◆ Your progress Everything stays on your device. Nothing is collected, nothing is sent anywhere. — CodeLock is made by Zarython. We build apps that make life easier.
