Number puzzle brain training — sixty stages of sliding tiles, played entirely on your device.
Last updated: 13 October 2026
Cipher: Logic Numbers is a single-player puzzle game. You slide numbered tiles into order; the game keeps your stage results, your prisms and your options on the phone or tablet you played them on. There is no sign-up, no profile to create, and nothing you have to give us in order to play.
The app may use a device identifier together with your saved preferences on the device to provide basic app functionality — remembering which stages you have cleared, how many prisms you hold, the name you typed on your record card, and the three switches on the Options screen.
It is used for one purpose: making the game work the way you left it. Your stage results decide which floors are unlocked, your prism balance decides what you can buy, and your options decide how the board is drawn. Nothing about your play is used for advertising or profiling.
We do not sell, rent or share your information with anyone. There is no advertising network in this game and nothing is put up for sale.
Everything the game remembers lives in the app's own local storage on your device, inside the app's private storage area. It stays there for as long as the app is installed.
Deleting the app removes it. On iOS, delete the app from the Home Screen; on Android, uninstall it from Settings › Apps. There is no copy kept anywhere else, so an uninstall is final — your cleared stages and prisms will not come back if you reinstall.
You decide what the game keeps. You can change the name on your record card at any time from the Record screen, and you can clear everything the game has stored by uninstalling the app. Because the game asks for no personal details and nothing leaves the device, there is nothing for us to look up, correct or hand back to you on request.
The game is suitable for a general audience and is not directed at children under 13. It asks for no personal details from anyone, whatever their age. If you are a parent or guardian and have a question about your child's use of the game, write to us at the address below.
