Popular Casino Games by Type
The best online casinos in the US offer a wide variety of games to match every playstyle — from fast, high-volatility slots to strategic, skill-based table games. Below, you’ll find the most popular online casino game categories along with quick tips on how to get started with each one.
Slots
Slots are the most popular online casino games thanks to their simple gameplay, fast-paced action, and potential for big payouts on a single spin. All you need to do is choose your bet size, press play, and watch the reels spin — making them ideal for beginners.
Online slots also offer incredible variety. You can enjoy classic 3-reel games with minimal features and low volatility, or dive into high-action Megaways slots with over 100,000 paylines, sharp visuals, massive jackpots, and bonus-packed features. From Ancient Greece and the Wild West to outer space and zombie adventures, there’s a slot theme for every taste.
Blackjack
Blackjack is one of the most popular table games at both land-based and online casinos. The rules are simple: try to get closer to 21 than the dealer without going over. But beyond the basics, it pays to learn when to hit, stand, split, or double down — especially if you’re playing for real money.
When played with optimal strategy, blackjack offers some of the best odds of any online casino game. Classic blackjack has a house edge of just 0.5%, and some online variants reduce that edge to as little as 0.14%. Compared to the average 4% house edge on slots, blackjack is a top choice for players looking to maximize theoretical payouts.
Video Poker
Video poker is widely available at top online casinos across the US It offers fast-paced gameplay, flexible betting limits, and a low house edge — as long as you make the right strategic decisions. Unlike traditional poker, you play against the house, not other players, so there’s no need for bluffing or complex reads.
The goal is simple: build the strongest possible five-card hand. Hands like a royal flush or straight flush can trigger significant payout multipliers. With its straightforward format and quick gameplay, video poker is a great choice for casual players who enjoy poker mechanics without the tournament pressure.
Roulette
Roulette has captivated players since its debut in the glamorous casinos of Monte Carlo in the 1860s. With every spin of the wheel, the suspense builds — offering a unique sense of drama that sets it apart from games like blackjack or video poker.
There are plenty of roulette betting options, from straight-up wagers on a single number to popular outside bets like red/black or odd/even. Many players enjoy experimenting with betting systems such as the Martingale or Paroli. While roulette carries a higher house edge than blackjack or video poker, it requires no strategic depth, making it ideal for casual play and excitement-driven sessions.
Craps
Craps is the most popular dice game at casino resorts across the United States. The table often generates a lively, communal atmosphere, with players cheering on the shooter and celebrating wins together. Online casinos have successfully brought that same energy to virtual and live dealer craps games, offering a full suite of betting options.
Compared to roulette, craps involves more strategic depth — and it rewards that strategy with a significantly lower house edge on certain bets. Our expert guide covers the smartest bets to make, the high-risk “sucker” bets to avoid, and how to improve your odds when playing online craps.
Scratch Cards
Online scratch cards are digital versions of the classic scratch-off lottery tickets you’d find in stores. Most online casinos group them under Instant Games, where you’ll find a wide variety of quick-play options. Gameplay is simple: just “scratch” a virtual panel to reveal hidden symbols or numbers — any matching combination results in a win.
Scratch cards have become one of the more popular betting games for US players thanks to their speed, simplicity, and instant win potential. Many online scratch card games now include bonus features, such as multipliers or mini-games, that can increase your payouts compared to traditional physical tickets.
The Most Popular Casino Games to Play
Slots, blackjack, online poker, and roulette are among the most popular casino games in the US, but each category offers many exciting variations. Below, we’ve spotlighted the top games within each type — including the most played titles and why they stand out.
1. Divine Fortune – Most Popular Slot Game
Divine Fortune is a progressive jackpot slot from NetEnt, featured at many top real money online casinos across the U.S. Set in the world of Ancient Greek mythology, the reels showcase symbols like Pegasus, Medusa, and the Minotaur.
This 5-reel, 20-payline slot has a strong return to player (RTP) of 96.59%, giving it a below-average house edge of just 3.41%. With the chance to trigger a jackpot that can exceed $1 million, Divine Fortune remains a favorite for players chasing big wins from a single spin.
2. Zappit Blackjack – Most Popular Blackjack Game
Zappit Blackjack is a fun twist on classic blackjack that gives players a second chance when dealt weak hands. If you’re dealt a total of 15, 16, or 17, you can choose to “zap” your hand — ending the round and getting your original bet back.
However, Zappit comes with a catch: if the dealer busts with a total of 22, your bet results in a push instead of a win. This rule bumps the house edge to 1.13%, which is higher than traditional blackjack. Still, the zap feature adds a strategic layer that many players enjoy.
3. French Roulette – Most Popular Roulette Game
French roulette is the best option for players seeking a low house edge. With just a single zero on the wheel, the house edge is only 1.35% — significantly lower than both European and American roulette.
French roulette often includes special rules like la partage, which refunds 50% of your even-money bet if the ball lands on zero, and en prison, which gives you a second chance to win on the next spin. These features are not found in European roulette, making the French variant the most player-friendly version available online.
4. Game King – Most Popular Video Poker Game
Game King is one of the most popular video poker platforms online, offering nine different variants in one place. These include Bonus Poker, Bonus Poker Deluxe, Double Bonus Poker, Double Double Bonus Poker, Triple Double Bonus Poker, Deuces Wild, Deuces Wild Bonus Poker, Joker Poker, and the fan-favorite Jacks or Better.
The goal across all variants is to build the best possible five-card poker hand — but the payout odds and house edge vary depending on the game. Deuces Wild offers the lowest house edge at just 0.28%, while Jacks or Better remains the go-to option for most video poker fans.
5. Ultimate Texas Hold ’Em – Most Popular Poker Variant
Ultimate Texas Hold ’Em is the most popular table poker game at U.S. online casinos. Similar to video poker, the goal is to build a strong five-card hand — but here, your hand is compared directly to the dealer’s. You receive two hole cards and share five community cards, making it a familiar format for Texas Hold’em fans.
The game is a bit more complex than video poker, 3 Card Poker, or Caribbean Stud, but it rewards strategic play. You also have the option to bet aggressively early in the round, adding excitement and control. With optimal decisions, the house edge drops to just 0.73%.
Live Dealer Casino Games
Live dealer games let you play in real time with a professional dealer, streamed from either a studio or a real land-based casino. These games are designed to recreate the experience of visiting a physical casino — but you can enjoy them from the comfort of your phone or computer, anytime.
You’ll place your bets digitally and watch the action unfold live. The dealer will deal cards or spin the roulette wheel while you interact through a built-in chat box, allowing for real-time engagement with both the dealer and other players. Below are some of the most popular options at the best live dealer casinos.
Live dealer blackjack
You’ll find a wide range of live blackjack games at top online casinos like BetMGM, DraftKings, FanDuel, BetRivers, and Caesars Palace. Options range from classic formats to popular variants such as Lightning Blackjack and Quantum Blackjack, which add exciting side bets and visual effects.
Infinite Blackjack is another standout, allowing unlimited players to join the same table — so you never have to wait for a seat. If real-money casinos aren’t available in your state, you can still enjoy live dealer blackjack using standard or premium coins at social casinos like High 5 Casino, Chanced Casino, Stake.us, Fortune Coins, or McLuck.
Live dealer roulette
Many players prefer live dealer roulette over virtual versions because the outcomes aren’t determined by a random number generator. Instead, a real wheel spin decides the result — creating a more authentic and visually engaging experience.
Top real money casinos for live roulette include FanDuel, DraftKings, Caesars Palace Casino, and BetMGM. These platforms offer classic American and European roulette, along with popular variants like Lightning Roulette. If you’re in a state without traditional online casinos, you can still enjoy live French roulette, European roulette, and auto roulette at social casinos like Chanced Casino.
Live dealer craps
Craps is another exciting live dealer option for online casino players. In this version, the dealer uses a mechanical shooter to launch the dice down the table, while you place bets like pass/don’t pass, come/don’t come, single-roll bets, and multi-roll wagers — just like at a land-based casino.
Currently, most platforms offer a single live craps game powered by Evolution Gaming. You can play it at apps like BetMGM, BetRivers, and DraftKings — but only in select states including Connecticut, Michigan, New Jersey, Pennsylvania, and West Virginia. If you’re outside those jurisdictions, the social casino BetRivers.net offers a fun version of live dealer craps you can play for free.
