We’ve narrowed the field to four platforms that show strong performance across usability, game access, and payout speed. Spartans, DraftKings, Fanatics, and BetRivers are setting the standard for what players expect from the best online casinos. Here's how they compare.
1. Spartans: A Crypto-First Platform Designed for Speed and Scale
Spartans.com has rapidly positioned itself as one of the best online casinos for users seeking more autonomy, quicker payouts, and extensive gaming options. Offering 5,963+ games from over 43 top-tier providers, the platform integrates slots, blackjack, roulette, crash games, and live casino titles alongside real-time sports betting, all through a single interface. It operates entirely on crypto, supporting Bitcoin, Ethereum, USDT, USDC, AVAX, and more.
That structure eliminates banking delays, enabling withdrawals that typically complete instantly. Players can connect wallets like MetaMask, Trust Wallet, or Coinbase Wallet to get started right away.
What makes Spartans stand out is its unified setup. There’s no need for separate logins between casino and sportsbook, it’s a single, streamlined account. New users can claim a 300% welcome bonus, daily 25% reloads, and participate in high-profile giveaways like a Lamborghini contest.
Optimized for mobile with a browser-friendly design, Spartans doesn’t require an app to deliver a smooth experience. An affiliate program with strong commission terms also attracts influencers and content creators. For those looking for a crypto-first platform with reliable features and fast execution, Spartans ranks as one of the best online casinos to explore in 2025.
2. DraftKings: Expanding From Sportsbook to Leading Casino Offering
DraftKings continues to expand its reach beyond sports betting, evolving into one of the best online casinos in the U.S. Its share price currently trades around $44.86, supported by Q1 2025 revenue of $1.41B. The platform now features over 110 in-house casino games, which account for nearly half of its casino activity. These exclusive games are presented in personalized lobbies with streamlined layouts.
Alongside these games, users can access live dealer tables, slots, and an integrated sportsbook using a single account. DraftKings emphasizes quick payouts, consistent promotions, and advanced responsible gaming tools. The company is also experimenting with prediction markets to increase reach in states with stricter regulations. Players who prefer licensed platforms with exclusive content and solid infrastructure will find DraftKings among the best online casinos available now.
3. Fanatics: Blending Sports Collectibles & Casino Betting
Fanatics is building on its background in sports merchandise to deliver a more integrated gaming experience in 2025. It has introduced new casino games, a solid sportsbook app, and high-value promotions. One current deal offers new users a $1,000 “no-sweat bet” on college football and ATP matches. Meanwhile, on the memorabilia side, the company auctioned Caitlin Clark’s rookie card for $660,000 and secured an eight-figure endorsement with BYU’s AJ Dybantsa.
Fanatics has set an ambitious revenue target of $11 billion by 2026 and is reinforcing its presence with initiatives like the 2025/26 Premier League trading cards and events such as Fanatics Fest. Users benefit from a single-account system that supports gaming and shopping, offering seamless access to both casino games and merchandise. With consistent product releases and a B+ credit rating reaffirmed by Fitch, Fanatics is emerging as one of the best online casinos by linking gameplay with real-world sports culture.
4. BetRivers: A Strong Pick for Poker Fans & Prop Betting
While BetRivers doesn’t always make headlines, it continues to add features that appeal to niche markets like poker and prop-style gaming. Since July 23, 2025, it has launched MLB PropPacks, bringing trading card-style bets to baseball, and expanded poker access in states like Delaware, Michigan, and West Virginia. These moves have created a shared player network that improves traffic and prize pool size.
The platform’s poker engagement is supported by events like “Knock Out a Pro,” hosted by Phil Galfond, and weekend tournaments with VIP incentives. In terms of bonuses, BetRivers offers a $500 second-chance bet for new signups and delivers smooth functionality across 15 states. While it doesn’t yet support crypto like Spartans, users benefit from fast withdrawals, dependable odds, and responsive customer service. Players interested in poker or creative formats like PropPacks will find that BetRivers continues to earn its place among the best online casinos.
