As online gambling continues its exponential growth, certain casino games stand out for bringing in the most revenue year after year. With many jurisdictions legalizing online betting and gaming sites utilizing advanced technology to improve the user experience, 2025 is on track to see all-time highs in total wagers and gross gaming revenue.
According to market research, these online casino games and variations are expected to make the most money in 2025:
Online Slots
In 2025 online slot machines remain the undisputed leader in casino game revenue by a wide margin. Their continuous popularity comes from the sheer variety of themes, bonus features and volatility to suit all players. Modern video slots, like those at Stake Casino, also utilize powerful graphics and sounds to immerse players in different worlds.
While classic 3-reel slots still have their fans, most of the profits come from 5-reel video slots with multiple paylines. The ability to bet small or go all-in with larger bets also appeals to players of all bankroll sizes.
Here’s a breakdown of the major slot categories expected to perform best in 2025:
| Type of Slot | Key Attributes | Top 2025 Titles |
| Branded Slots | Based on hit movies, TV shows, musicians | Game of Thrones, Jurassic Park, Elvis The King |
| Megaways | 117,649 paylines or more | Bonanza, Piggy Riches Megaways |
| Progressives | Pool jackpots from multiple players | Mega Moolah, Wheel of Wishes |
| VR Slots | Immersive 3D world with VR headset | StarburstVR, Gonzo’s Quest VR |
Online Poker
While poker has declined a bit from its peak around 2010, it still maintains a strong community of enthusiastic players. The game’s reliance on skill versus pure chance gives it an appeal lacking in slots or roulette. Top sites continue marketing to poker players with bonuses, tournaments and tiered loyalty programs.
The no-limit Texas Hold ’Em variation makes up close to 85% of online poker traffic. But Omaha, 7-Card Stud and fast-fold poker also contribute to revenue. Leading sites in 2025 include America’s Cardroom, PokerStars VR and Ultimate Poker.
For supported markets, live dealer poker with a real human dealer also gives players more trust in game integrity and social interaction lacking with RNG poker.
Online Roulette
In the battle for table game profits, roulette holds the number one spot. Its inclusion of both inside and outside bets makes it friendly for casual gamblers and serious players alike.
Like online slots, modern RNG roulette includes many variations like double ball, multi-wheel and live dealer with real wheel spins. Players in 2025 also have their choice of American or European rules. This variety keeps the game feeling fresh.
Key factors contributing to roulette’s ongoing popularity:
- Simple rules and betting options
- Fast pace (no waiting on other players)
- Works on all devices with smooth software
- Live dealer additions for social experience
Blackjack
As a game combining both luck and skill, blackjack has maintained a consistent player base for decades. Top sites utilize continual shuffling to eliminate card counting. But the basic concept has remained the same since the 1700s.
In 2025, most real money blackjack revenue comes from:
- 6 or 8 deck RNG games with popular rule variations
- Single & double-deck games (often live dealer)
- Blitz blackjack – faster pace with just 14 cards dealt
A few top online casinos even offer live blackjack tournaments, with buy-ins starting around $10 USD.
Baccarat
While not as widely known in the West, baccarat has become an online casino staple thanks to its popularity in Asia. The game has simple rules with no strategy involved, making it appealing to casual gamblers.
Most real money baccarat revenue comes from live dealer games. Players can bet alongside others and watch real cards being drawn from a dealing shoe. High rollers also frequent VIP baccarat rooms with table limits exceeding $10,000 USD per hand.
A few top sites in 2025 even integrate live streams from land-based casinos to interact with players half a world away. Cryptocurrency betting has also boosted baccarat profits.
Craps
As one of the more social casino table games, craps has adapted well to live dealer streaming technology. Players can chat while watching dice rolls play out in real-time.
Simplified mobile apps also allow real money craps games with digital dice. But most revenue still comes from the traditional game with pass/don’t pass bets, odds wagers and numbers propositions.
A few key craps variations gaining popularity in 2025:
- Single roll bets
- Simplified street craps rules
- Progressive jackpot bets
Thanks to increased legalization, more US players have access to real money craps compared to past years.
Online Bingo
While the bingo hall stereotype persists in some regions, modern online bingo sites have completely revitalized this classic game. Younger demographics are joining chatty live bingo rooms where friendships and community thrive.
Top sites in 2025 utilize strong bingo software for smooth gameplay across devices. Side games like online slots and instant win also boost profits. Some key trends keeping bingo profitable:
- Mobile optimization with native apps
- Loyalty clubs and tiered rewards
- Branded content (Playboy, Deal or No Deal)
- Live dealer balls drawn every few minutes
Keno
As an online casino game, keno broadly appeals to fans of both lottery drawings and bingo. Players can bet on anywhere from 1 to 15 numbers per draw. Payouts scale up astronomically for hitting 10 or more matched spots.
Top keno sites utilize RNG draws every few minutes for speedy gameplay. Some live dealer versions also exist with real ball drawing machines. Key keno trends in 2025 include:
- Betting side games during draws
- Progressive jackpots from one draw to the next
- Quickbet options for fast play
- Potential wins up to $500,000+ USD
Video Poker
While video poker lacks the hype of slots and table games, it still boasts a thriving community of strategy-focused players. Top online casinos offer over a dozen video poker variants – each with perfect play charts to maximize returns.
A few key video poker trends keeping profits consistent:
- Multi-hand games to boost action
- Live dealer options in supported markets
- Progressives with pools exceeding $100K
- Quick action on mobile
Thanks to sheer variety and low minimum bets, video poker should remain popular for years to come.
Baccarat Squeeze
As a slick variation on traditional baccarat, “squeeze” builds anticipation by slowly revealing card values. Players can bet alongside others and use chat features while the dealer squeezes each card at a diagonal.
This simple twist keeps every coup exciting while maintaining baccarat’s classic rules. Although more of a niche title now, live baccarat squeeze tables could catch on in 2025 among casual and serious players alike thanks to the social experience.
Those are the top 10 online casino games positioned to generate the most gross gaming revenue in 2025. Slots may dominate the market, but innovation with table games and even specialty titles like bingo promises to keep overall profits diversified.
As technology expands with VR casinos and continued mobile optimization, players in most regulated markets have an ever-growing selection of instant play games. Now is the perfect time to take your real money gaming experience to the next level!
