Gambling Game Guide for Iowa Players
Whether you're visiting a casino in Iowa or playing the state lottery from home, understanding the rules and odds of each game is essential. Below is a summary of every major gambling type available to Iowa residents.
Blackjack
Blackjack — also called 21 — is the most widely played casino banking game in the world. Players compete against the dealer rather than each other, aiming to build a hand whose point total is closer to 21 than the dealer's without exceeding it. The simplicity of its core objective, combined with a low house edge and a meaningful skill component, makes blackjack the preferred game of millions of casino visitors.
Roulette (American)
American Roulette is the version found in most US casinos. The wheel features 38 pockets: numbers 1–36 alternating red and black, plus a green 0 and a green 00. The additional double-zero pocket is what distinguishes American from European roulette and increases the house edge. Despite the worse odds compared to European roulette, American roulette remains extremely popular for its fast pace and wide variety of bets.
Roulette (European)
European Roulette features a 37-pocket wheel with numbers 1–36 and a single zero (0). By eliminating the American double-zero, the house edge drops from 5.26% to 2.70%, making it significantly more favorable to players. Many European casinos also offer the "La Partage" rule, which returns half of even-money bets when the ball lands on zero, reducing the house edge further to 1.35%.
Baccarat
Baccarat is one of the oldest and most prestigious casino card games, long associated with high rollers and elegant casino salons. The game's appeal lies in its simplicity — players have only three betting options and no decisions to make after placing their bet. The low house edge on the Banker bet makes baccarat one of the best wagers in the casino.
Craps
Craps is the most exciting game on the casino floor. Players wager on the outcome of dice rolls, and the communal energy around a hot craps table is unmatched. The game has an intimidating layout, but the core bets are simple, and the Pass Line with odds offers one of the best bets in the entire casino — in some cases with a near-zero house edge.
Three Card Poker
Three Card Poker is one of the most successful casino table game inventions of the modern era, created by Derek Webb in 1994. It combines the simplicity of poker hand rankings with the speed of a house-banked game. Players compete against the dealer with just three cards, and the game offers two independent betting opportunities: Ante/Play and Pair Plus.
Caribbean Stud Poker
Caribbean Stud Poker is a five-card stud poker variant played against the house. It gained popularity on cruise ships in the Caribbean before spreading to land-based casinos worldwide. The progressive jackpot side bet — which can reach life-changing sums — is a major draw, though it carries a very high house edge.
Pai Gow Poker
Pai Gow Poker is an Americanized version of the Chinese domino game Pai Gow, adapted to use playing cards and standard poker hand rankings. Players receive seven cards and must arrange them into a five-card "high" hand and a two-card "low" hand. The slow pace and frequency of pushes give it one of the lowest volatility profiles of any casino table game.
Let It Ride
Let It Ride is a poker-based table game developed by Shuffle Master in the early 1990s. Unlike most casino card games, players can withdraw two of their three initial bets as the hand develops — but only if they choose. The name comes from the option to "let it ride" rather than take back bets. The game is based on five-card poker hands built from three player cards and two community cards.
Sic Bo
Sic Bo is an ancient Chinese dice game whose name means "precious dice." Players bet on the outcome of a roll of three dice. The complex betting layout offers dozens of wagering options with wildly varying payouts and house edges. Sic Bo is popular in Asian casinos and is found in most major US and international casinos, particularly those catering to Asian customers.
Texas Hold'em Poker
Texas Hold'em is the world's most popular poker variant and the format used in the World Series of Poker Main Event. Unlike casino-banked table games, players compete against each other, not the house. The casino earns revenue by taking a rake (small percentage) from each pot. Skill, psychology, and game theory all play major roles in long-term success.
Omaha Poker
Omaha Hold'em (commonly called Omaha) is the second most popular poker variant worldwide. It shares the community card structure with Texas Hold'em but with a crucial difference: players receive four hole cards instead of two and must use exactly two of them (no more, no fewer) combined with exactly three community cards to form their best five-card hand. This mandatory use of exactly two hole cards creates dramatically different hand values and much heavier action.
7-Card Stud
7-Card Stud was the dominant poker variant in America before Texas Hold'em overtook it in the 1980s and 1990s. It is still widely played in casinos, home games, and online, particularly in mixed-game formats like H.O.R.S.E. Unlike Hold'em, there are no community cards — each player builds their hand entirely from their own seven cards, four of which are exposed face up for all players to see.
Video Poker
Video Poker is the bridge between slot machines and table poker. Players are dealt five cards from a virtual deck and choose which to keep before receiving replacements. The resulting hand is paid according to a fixed pay table. With correct strategy, some video poker variants return over 99% — even over 100% on rare "positive expectation" machines — making video poker one of the best bets in the casino.
Slot Machines
Slot machines are by far the most popular form of gambling in land-based casinos, accounting for the majority of casino floor space and revenue. Modern slots are sophisticated computer programs using Random Number Generators (RNGs) to determine outcomes. They range from penny machines to $100-per-spin high-limit slots and offer themes from ancient mythology to blockbuster films.
Keno
Keno is a lottery-style casino game with ancient Chinese origins. Players select numbers from a grid (typically 1–80) and the casino randomly draws 20 numbers. Payouts depend on how many of the player's chosen numbers match the drawn numbers. Keno is found as a standalone game, an electronic machine, a lounge game running continuously in casinos, and as a state lottery offering.
Bingo
Bingo is one of America's most beloved social gambling activities. Players purchase cards printed with a 5x5 grid of numbers (B: 1–15, I: 16–30, N: 31–45, G: 46–60, O: 61–75, with a free center square). A caller randomly draws balls and announces numbers; players mark matching numbers on their cards. The first player to complete a specified pattern shouts "Bingo!" and wins the prize.
Pull Tabs
Pull tabs are paper or cardboard cards with perforated tabs that players tear open to reveal hidden symbols. If the symbols match a winning combination printed on the card, the player wins a prize. Pull tabs are common in bars, bingo halls, charitable gaming venues, and many states' tribal casinos. They are sometimes called "breakopen tickets" or "tip boards."
Sports Betting
Sports betting is wagering on the outcome of sporting events. Following the Supreme Court's 2018 ruling in Murphy v. NCAA, individual states gained the right to legalize sports betting. As of 2024, more than 35 states plus Washington D.C. have legal sports betting. The industry has grown into a multi-hundred-billion-dollar market, with professional leagues now openly partnering with betting operators.
Horse Racing
Horse racing is one of the oldest forms of gambling in America, with a legal pari-mutuel wagering structure that was specifically exempted from federal gambling prohibitions. Pari-mutuel betting means all bets on a race go into a pool; the track takes a cut (the takeout), and the remaining money is divided among winning bettors. The more money bet on a horse, the lower the odds and payout.
Dog Racing / Greyhound Racing
Greyhound racing involves betting on which dog will finish first (or in a specific combination of places) in a race. Like horse racing, it uses pari-mutuel wagering. Greyhound racing has declined significantly in recent decades due to animal welfare concerns. Florida voted to ban greyhound racing in 2018, and as of 2024, only a handful of tracks remain operational in the United States (primarily in West Virginia, Iowa, and Arkansas under limited circumstances).
Jai Alai
Jai Alai (pronounced "Hi-Li") is a fast-paced court sport originating from the Basque Country. Players use a wicker basket (cesta) strapped to their hand to catch and hurl a hard rubber ball (pelota) against a three-walled court at speeds exceeding 150 mph, making it one of the fastest ball sports in the world. Historically prominent in Florida and Connecticut, jai alai has declined dramatically; only a few frontons still operate in the US.
State Lottery
State lotteries are government-run gambling operations found in 45 states, Washington D.C., Puerto Rico, and the U.S. Virgin Islands. They are the most widely accessible form of legal gambling in the US. Lottery revenues fund state programs including education, infrastructure, and senior services. Despite the terrible odds of winning large prizes, lotteries generate tens of billions of dollars in ticket sales annually.
Scratch Cards (Instant Tickets)
Scratch cards (instant tickets or scratchies) are lottery tickets where the player scratches off a latex covering to reveal symbols or numbers, winning instantly if the results match the game's prize conditions. They are sold by state lotteries and found in virtually every convenience store. Prices range from $1 to $50 per ticket, with top prizes ranging from $100 to $10 million or more.
Powerball
Powerball is the flagship multi-state lottery game sold in 45 states, Washington D.C., Puerto Rico, and the U.S. Virgin Islands. Jackpots start at $20 million and often reach hundreds of millions — even billions — of dollars, making it the source of some of the largest lottery prizes in world history. Drawings are held every Monday, Wednesday, and Saturday night.
Mega Millions
Mega Millions is the other major multi-state lottery sold in 45 states and D.C. (not sold in Alabama, Alaska, Hawaii, Nevada, or Utah). Like Powerball, it offers jackpots starting at $20 million that grow until won, reaching record-breaking levels. The largest Mega Millions jackpot in history was $1.602 billion (October 2023). Drawings are held every Tuesday and Friday night.
Online Casino
Online casinos offer digital versions of traditional casino games accessible from computers and mobile devices. In the US, online casino gambling (iGaming) is currently legal and regulated in New Jersey, Pennsylvania, Michigan, Connecticut, Delaware, West Virginia, and Rhode Island, with additional states considering legislation. Licensed online casinos offer blackjack, roulette, baccarat, craps, slot machines, video poker, and live dealer games streaming from studios or actual casino floors.
Online Poker
Online poker allows players to compete in real-money card games from anywhere via computer or mobile device. Following the Black Friday shutdown of unlicensed sites in 2011, legal US online poker now operates within state-licensed frameworks. Nevada, New Jersey, Pennsylvania, Michigan, Delaware, and West Virginia all have regulated online poker. Some states share player pools across state lines, creating larger games.
Online Sports Betting
Online sports betting (mobile sportsbooks) is the fastest-growing segment of the US gambling market. Apps from major operators like DraftKings, FanDuel, BetMGM, Caesars, and ESPN Bet allow bettors in legal states to place wagers instantly from anywhere in the state. The convenience of mobile wagering has made online sports betting dramatically larger than retail (in-person) sports betting in most markets.
Fantasy Sports (Season-Long)
Season-long fantasy sports leagues are competitions where participants draft real professional athletes and score points based on those athletes' actual statistical performances over a sports season. Fantasy sports are generally classified as games of skill rather than gambling under US federal law (the UIGEA specifically carves them out), making them legal throughout the country. Major platforms include ESPN Fantasy, Yahoo Fantasy, Sleeper, and NFL.com.
Daily Fantasy Sports (DFS)
Daily Fantasy Sports (DFS) compresses the fantasy sports experience into a single day or week. Players build rosters within a salary-cap budget and compete for cash prizes. DraftKings and FanDuel dominate the US DFS market. DFS is legal in most states (about 46) and is explicitly protected as a game of skill under most state laws. High-volume, highly analytical "sharps" (professionals) win a disproportionate share of prizes, particularly in large-field tournaments.
Esports Betting
Esports betting is wagering on the outcomes of competitive video game tournaments and matches. The global esports betting market has grown rapidly alongside the professionalization of games like League of Legends, CS:GO (Counter-Strike 2), Dota 2, Valorant, Call of Duty, and FIFA/EA Sports FC. Esports markets are available at most major sportsbooks. The audience skews young, and many states with legal sports betting explicitly include esports in their regulatory frameworks.
