CodeLock

Your grandfather left you a letter, four vaults, and a road nobody finished. In CodeLock you crack codes to open vaults, and each one gives up a piece of his letter. The more of it you hold, the clearer it becomes what he spent his life looking for — and why seven of his own ancestors died short of it. ◆ How it plays The code is digits, no digit twice. You enter a guess, and the vault tells you exactly two things: how many digits are in the right place, and how many are right but in the wrong place. Never which ones. The rest is your head. It looks simple on level one. By level sixty you are drawing a grid on paper. ◆ Four eras • The Last Drawer — a painted house safe, and your grandfather's desk exactly as he left it • Under the Sand — a dig in the desert, and a stone door shut for thousands of years • The Only Survivor — a salt-eaten sea chest, where the whole story began • Before Speech — a grooved stone disc, the oldest lock humankind ever made Every chapter ends on a lock your grandfather built himself, not one a machine generated. Guessing will not open it. What you learned from his papers will. ◆ What you get • 90 levels, climbing from four digits to seven • Letter fragments, collected one level at a time • Evidence that piles up — and you have to work out which piece belongs where • One daily challenge, the same for every player on earth — the code comes from the date itself • A monthly gift calendar, achievements, and statistics that tell you how much you actually improved • Tools you buy with what you earn: hint, reveal a digit, rule one out ◆ What you do not get No ads. No in-app purchases. No account, no sign-in. And no internet needed — it plays in full offline. Coins and gems are earned by playing and cannot be bought. A game about opening locks with your head has no business opening to money. ◆ In your language English · Deutsch · عربي — written and designed in each, not machine-translated. ◆ Your progress is safe Sign in with Play Games if you like, and your progress survives a new phone. If you would rather not, the game stays complete — everything lives on your device alone. — CodeLock, by Zarython.
