Phone login and account security — a few important points
When using the app on mobile, it is important to stay careful about security. Keep your phone screen lock active before logging into the app — whether you use a PIN, pattern or fingerprint.
If OTP verification is needed when logging in, use it immediately and do not share it with anyone. Never share your password with anyone — no 399 days support agent will ever ask for your password.
It is best to avoid logging in on public Wi-Fi or someone else's phone. Using the app on your personal device on your personal network is the safest option.
Keep screen lock active
Always keep your phone's screen lock on to prevent unauthorised access to the app.
Keep your OTP private
Do not share your login OTP code with anyone — it is for your use only.
Do not share your password
Never share your password with anyone, even someone claiming to be support.
Avoid public Wi-Fi
Avoid logging in on public networks — use your own mobile data or home network.
Useful tips for running the app smoothly
-
01
Maintain a stable internet connection
A weak connection during live casino or live betting can disrupt streaming or odds updates. Being on 4G or a good Wi-Fi connection makes for a much better experience.
-
02
Keep the app up to date
New updates add games, improve security and fix performance issues. Get updates from official channels only — not from any other source.
-
03
Close background apps
Running too many apps at once can slow your phone down. Closing unused apps before starting a game keeps graphics and loading smoother.
-
04
Keep an eye on battery and storage
During long gaming sessions, a low charge can cause the phone to shut off unexpectedly. Start playing with enough charge and keep enough storage free.
-
05
Contact support if you have a problem
If the app does not load or a payment error appears, immediate help is available through the app's live chat — the support team is ready 24 hours a day.
