Game 2 of 5 · Deduction
Code Vault
Crack the gem code, one clue at a time.
A hidden code of gemstone symbols guards every vault. After each guess, brass pegs tell you how many gems are in the right place and how many are in the code but elsewhere, never which ones.
- 25 onboarding vaults
- Longer codes and repeated gems later
- No timer
- A fresh code is always free

Your progress
There is no account. Your progress and settings are saved on your device only, and nothing is sent to us. Deleting the app deletes them, and we can't restore them. Settings → Reset progress starts over.
Ads
Code Vault never shows an ad you didn't ask for: no banners, no pop-ups between vaults. Each vault offers one optional hint, unlocked by watching a short ad. A hinted vault earns at most 2 stars. Closing the ad early gives no hint and costs nothing.
Privacy choices
Where the law requires it, the game asks for your ad choices on first launch. To change them later, open Settings in the game and tap Privacy choices. Read the full privacy policy and terms of use.
