Terms of use

Updated 5 October 2026

The service

Lucimind is a set of brain games, published by Luci Studio: a daily workout and a Daily Challenge. It is free, with ads, and Premium removes the ads. The games are for fun and practice: we make no promise that they improve your health, your results at school or work, or your IQ.

Age

You must be 16 or older to use Lucimind.

A connection to start a game

Starting a game needs an internet connection, with Premium too. Everything else works offline, and a game finished offline counts once you are back online.

Premium

Premium is a subscription bought through the App Store or Google Play. It renews automatically; cancel it at any time in your store's settings, at least 24 hours before it renews. While it is active, there are no ads.

Coins and lives

Coins are earned in the app or bought, and spent in the app on games and lives. Coins and lives have no cash value.

Accounts

Your account starts without a way to sign in. Add Apple or Google in the app to keep your progress on a new phone; without one, a lost phone loses the progress. To delete your account, see Deleting your account.

Names and conduct

A display name has 3 to 16 letters, digits, spaces, dots, underscores or hyphens, and some names are refused. Other players can report a name: after three reports it is removed, and you pick another. You can block a player: it ends your friendship and hides each of you from the other's boards.

Daily Challenge rankings

A result counts in the day's ranking when our server's replay of your moves confirms the solve, you played that day's puzzle with the clock on, the result arrived by 12:00 UTC the next day, and your account is at least a day old and has finished a workout game. Puzzles from the archive never count.

On iPhone

If you got Lucimind from the App Store, Apple's standard licence agreement applies too.
