Useful tips

From the ui77 app How to Get the Most Out of It

Do these after installing the app to get the most out of your experience

Keep Notifications On

After installing the app, allow notification permissions. ui77 regularly sends bonus and cashback offers — you will miss them if notifications are turned off.

Set Up Biometric Login

Enable fingerprint login from the app settings. No more typing your password every time.

Best performance on WiFi

Use WiFi when playing Live Casino or HD streaming games — it significantly reduces lag compared to mobile data.

Keep the App Updated

Update the ui77 app as soon as a new version is released. Every update includes bug fixes, new games, and performance improvements.

Turn off battery saver mode on your phone during live games — it throttles screen brightness and processor performance, which can disrupt gameplay.

Download from Official Links Only

Only download the ui77 app from the official download page at ui77.win. Downloading APKs from third-party sites carries security risks.
