FAQ

The most common questions asked after registration

After logging in, click your profile icon in the top right corner. Under the "Account" or "History" section, you will find two separate options — "Betting History" and "Transaction History". Betting History shows which games you placed bets on, whether you won or lost, and a full breakdown of any bonus usage. Transaction History lists the date and amount of every deposit and withdrawal. You can filter by date to view records for a specific period. If needed, you can also request a detailed statement from our support team.

The Live Casino section might feel a little unfamiliar at first, but it's actually quite simple. Open the app or website and go to the "Casino" section — you'll find a dedicated area labelled "Live Casino". There, real dealers are running various games live; Baccarat, Roulette, and Dragon Tiger are among the most popular. Click on any table and the live stream will start instantly. You'll see the betting options at the bottom of the screen — just enter your amount and hit the "Bet" button. Start with a small bet your first time and gradually increase it as you get comfortable. If you're unsure about the rules, just reach out to support.
