What we know about you.

Your score, best result, statistics and unfinished game are stored on the device itself. They stay on the device and disappear when you delete the game. On Apple devices they may be included in a device backup, like the data of any other app.

They leave the device only through the platform's own services (Game Center on Apple devices, Google Play Games on Android and Yandex Games wherever you open it) and through the weekly board. See below.

The iPhone, iPad and Android versions show advertising from Yandex. Its module processes technical information about the device: model, system version, language, approximate location derived from the IP address and the advertising identifier. This data is processed by Yandex, not by the studio; the AppMetrica analytics system from the same vendor ships with the ad module. Details are in the Yandex privacy policy.

Ad requests are marked as intended for all ages, so interest-based advertising is not requested. The macOS version carries no advertising at all.

On iPhone and iPad the system asks for tracking permission on the first launch. The request comes from the ad module itself: it reads the advertising identifier, and without permission the system hands it zeros instead. Declining breaks nothing — the game works the same and the advertising simply stays untargeted. The answer can be changed in device settings at any time.

On Apple devices the result of a finished game is submitted to a Game Center leaderboard if you are signed in. On Android the same role is played by Google Play Games. What other players see — your score and the nickname you chose — is governed by the settings of those services, not by the game: the studio has no access to your Apple or Google account.

When a game ends, the game sends the studio's leaderboard server the game's random seed, its list of moves and the pauses between them. The server replays the game to check the score and keeps the record so that other players can watch it. The player is identified by a random number created on the device; on Apple devices, by a salted one-way hash of the Game Center player ID, and the ID itself never leaves the device. Nothing else is sent. On the board a player appears under a nickname the server makes up from ordinary words; on Apple devices Game Center shows your own nickname instead.

The server runs in Yandex Cloud, and the records are stored in a database hosted by Supabase. A record leaves the weekly board when the week ends.

This version follows the platform's rules, whether you open it in a browser or in the Yandex Games app on a phone, tablet or TV. Saved games and the leaderboard live on the platform's server, and the advertising is its own. If you are signed in to a Yandex account, your progress is tied to it and carries between devices. Details are in the Yandex privacy policy.

The site runs no analytics and counts no visits. The only cookies that may appear are the service cookies of Cloudflare, which serves the connection. Fonts are loaded from Google Fonts, and that service sees the IP address of the request — the only way around it would be to drop external fonts.

The game is not designed to collect data from children and requests no information from players of any age.

If the set of services used changes, this page will be updated and the date at the top revised.
