MyBookie Sister Sites

MyBookie has grown beyond a single sportsbook and now sits at the center of a small family of gambling brands that target different player needs. From sportsbook-first options to casino-focused properties with multi-currency support, these sister sites give U.S. players choices for payment methods, game libraries, and bonus structures without leaving the same brand ecosystem. Below I break down the key differences so you can quickly see which site might fit your preferences.

Standout payment methods and currency coverage

If fast, familiar payment rails matter, the group covers the usual options and a few niche channels. MyBookie supports a wide range of deposit and withdrawal methods including Bank Wire Transfer, MoneyGram, Western Union, and major cards. Fliff Sportsbook focuses on simplicity with MasterCard and Visa, plus mobile-friendly access. SportsMillions Casino accepts Apple Pay and Google Pay for mobile convenience, while Carnival Citi Casino and Mandarin Palace Casino offer card-heavy options and e-wallets like Neteller and Skrill. Mandarin Palace also supports multiple currencies (AUD, CAD, EUR, GBP, SEK, USD), which makes it a better match for players outside the U.S. looking for localized banking.

Bonuses and welcome offers that catch attention

Welcome deals vary widely across the group, and the math behind them is important. MyBookie leads the pack for large sportsbook and casino-style offers: a 150% bonus up to $750 with code "MYB150," a 50% bonus up to $1,000 plus free bracket entry with "MYB50," a 100% crypto bonus up to $1,000 for first crypto deposits using Bitcoin or Ethereum, and a massive 300% match up to $2,000 with 50 free spins via "WELCOME300." Remember that percent values, maximum caps, and playthrough or multiplier requirements differ from offer to offer, so check terms before depositing.

Mandarin Palace markets a high-value slots-focused package—200% up to $4,000 plus 40 free spins on Destiny Wild (code "200PALACE")—but it carries a higher playthrough requirement. Fliff promotes 100 free bets for sportsbook players, while Carnival Citi and SportsMillions keep things simple with smaller, game-specific welcome deals like “10M Coins & Free SC 5,000” and “Deposit $10 Get $59,” respectively.

Software lineups that shape game selection

Game libraries reflect different software mixes. MyBookie hosts a broad stable of suppliers—Betsoft, Evoplay, Spade Gaming, KA Gaming, and others—so you’ll find both slots and table games across many studios. Mandarin Palace leans on Betsoft and Rival Gaming for slots and classics, and SportsMillions brings in Pragmatic Play, Habanero, and Booming Games among others. Carnival Citi features Endorphina and KA Gaming for a more curated slot offering.

Customer support and accessibility

Support options are straightforward but vary in reach. Most brands offer live chat and email: MyBookie, Carnival Citi, SportsMillions, and Fliff provide chat plus email support. Mandarin Palace stands out with multiple toll-free numbers covering the U.S., Canada, the U.K., Australia, and international callers, as well as email support. That phone coverage can matter if you prefer voice support for cashouts or account issues.

Which site matches what kind of player

If you want a full-service sportsbook with many deposit channels and a wide pool of promos, MyBookie remains the most complete choice.
For quick mobile deposits and a tight sportsbook experience, Fliff is worth a look.
If you’re after slots with large match bonuses and multi-currency banking, Mandarin Palace fits that profile.
SportsMillions and Carnival Citi are better for players who want simple, low-friction casino promos or compact game libraries.

Compare payouts, playthroughs, and support before you commit

Sister sites offer clear benefits—payment diversity, distinct software libraries, and tailored bonus packages—but the differences matter when it comes to withdrawal speed, playthrough requirements, and customer support availability. Review the terms for each welcome bonus, check which deposit methods you prefer, and pick the brand that lines up with how you like to play.
