Settings control how the app looks and behaves on your device. They do not affect progress: none of them can be tuned to give an advantage.
Interface
Game language — Russian, English, or Spanish. It changes both the interface and the in-game texts. The choice is stored on your account, so it carries over to other devices.
Graphics quality — affects the 3D scenes: the lobby, the profile, and arena battles. If animations stutter or the phone heats up, lowering the quality is the first thing that helps.
Haptics — a short response on a successful tap. Turn it off if it gets in the way.
When the game behaves oddly
Settings include a cache reset: the app clears its stored data and reloads. It is the first thing to try when screens show stale numbers, images fail to load, or something breaks after an update.
Progress, items, and currencies are not lost — they live on the server, not in the device cache.
The same screen shows the app version and build time. Mention them when writing to support: they show whether your app has actually updated.
Legal documents
The terms of service, privacy policy, and refund terms open from settings, along with the date each document was last updated.
