The Floor Is Organised by Machine, Table, and Screen
Walk into any casino and the first thing you notice is that the games are not scattered at random. They are grouped. The machines sit in long banks, the tables occupy their own carpeted islands, and in many venues a third category, the electronic table or stadium game, bridges the two. Understanding those three physical zones answers most of the question before you look at a single rule sheet.
Machines are the largest group by floor space. These are games you play alone against the software: slots in their many visual forms, video poker, and increasingly electronic versions of roulette and blackjack. Tables are the games with a dealer or croupier and a felt layout: blackjack, roulette, craps, baccarat, and the poker-room tables where you play against other players rather than the house. The third zone, electronic table games, puts a live dealer or a shared wheel on a screen while you bet from a terminal, often at a lower minimum than the physical table next to it.
That zoning matters because it tracks a real difference in how the games work. On a machine, the outcome comes from a random number generator and the pace is yours. At a table, cards are dealt or a wheel is spun in front of you, and the pace belongs to the whole table. The categories below are the ones you will see on any game list, online or on a floor map.
Slot Machines and Their Many Formats
Slots are the most numerous games in any casino, and the term now covers a wide family. The basic mechanism is the same across all of them: you stake a wager, the reels or grid resolve through a random number generator, and a paytable decides what any given combination returns. What changes between formats is how combinations are counted and how the prize is structured.
Classic three-reel slots keep a small number of symbols and a single payline. Video slots add bonus rounds, free-spin features, and themed presentation. Ways-to-win games abandon fixed lines entirely and pay on adjacent-symbol combinations, which changes how many possible winning paths exist on every spin. The payline and ways-to-win distinction is worth reading carefully on any game's information panel, because it determines whether you are betting all lines or a single stake across every possible path.
Jackpot structure is a separate axis. A fixed jackpot pays a set amount printed on the paytable. A progressive jackpot grows from a share of qualifying wagers and resets after it is won. Progressive contributions are typically taken out of the game's return, and some progressives require a maximum-stake bet to qualify at all. None of this changes the core fact that a slot is a negative-expectation game; it only changes the shape of the prizes.
Table Games: Cards, Wheels, and Dice
Table games are where the house edge is most visible, because the rules are printed on the felt and the bets are made in the open. The four families below cover most of what you will find.
| Game | What you are betting on | What changes between tables |
|---|---|---|
| Blackjack | A hand total closer to 21 than the dealer's, without exceeding it | Deck count, dealer stand rules, doubling and splitting rules |
| Roulette | Where a ball lands on a numbered wheel | European wheel (37 pockets, single zero) vs American wheel (38 pockets, double zero) |
| Craps | The outcome of two dice, primarily through the pass line and come-out roll | Bet type; different bets on the same table carry materially different edges |
| Baccarat | Which of two hands, player or banker, totals closer to 9 after modulo 10 | Banker, player, and tie bets carry different house edges |
Blackjack is the most decision-heavy of the four. Published basic-strategy charts exist, but they derive from the specific rule set in use, so a chart for one table does not transfer cleanly to another with different doubling or dealer-stand rules. Roulette is the most decision-light: every bet is a wager on where the ball lands, and the main strategic fact is which wheel you are playing, because the extra double-zero pocket on the American layout increases the house edge. Craps looks chaotic but is built around the pass line and the come-out roll, with a long tail of side bets that carry very different edges. Baccarat is a comparing game with no player decisions after the bet is placed, and the tie bet carries the highest house edge of the three main options.
Poker, Video Poker, and the Player-Versus-Player Distinction
Poker occupies a different position in the casino because the house does not bank the game in the same way. In a poker room, you are playing against other players, and the venue takes its revenue from a rake or a time charge on each hand or session. That changes the strategic picture entirely: your expected result depends on the skill gap between you and the other players, not on a fixed house edge built into the game.
Video poker is the machine-based cousin, and it sits closer to slots in structure. You are dealt a hand, choose which cards to hold, and the draw resolves through a random number generator. The paytable is printed on the machine, and small differences in that paytable change the game's return. Video poker is one of the few machine games where the player's choices genuinely affect the expected rate of loss, because holding decisions are not neutral.
Electronic Table Games and Hybrid Formats
The third zone on a modern floor is the electronic table. These games keep the rules of a table game but deliver them through a screen: a live dealer on video, a shared physical wheel, or a fully simulated table with a virtual dealer. You bet from a terminal, often alongside other players betting on the same outcome.
The appeal is usually a lower minimum bet than the physical table and a faster pace, because there is no waiting for chips to be counted or for other players to act. The rules are the same rules, so the house edge on an electronic roulette wheel is the same edge as on the physical wheel next to it, assuming the same wheel type. What changes is the speed of decisions per hour, which matters to anyone tracking their expected loss over time.
How to Read Any Game List
When you open a casino's game list, whether on a floor map or in an app, the categories above are the filter. Most lists sort by game type first: slots, table games, video poker, live dealer, and sometimes a separate section for jackpots or new releases. Within slots, you will often see sub-filters for themes, features, or volatility, though volatility is a distribution of payouts, not a measure of return.
The information panel on any individual game is where the real numbers live. It shows the paytable, the payline or ways-to-win structure, the betting range, and in many jurisdictions the theoretical return to player. RTP is a long-run statistical average over a very large number of spins or hands, not a per-session guarantee, and it is the complement of the house edge for the same game under the same rule set. A game with a high RTP has a small house edge, and neither number tells you what will happen in the next hour.
For table games, the equivalent information is on the felt and the placard: minimum and maximum bets, rule variants like dealer stand rules in blackjack, and the payout schedule for each bet. The placard is the table's terms sheet, and it is worth reading before you sit down, because two blackjack tables in the same venue can have different rules and therefore different edges.
FAQ
What is the difference between a slot and a table game in terms of how outcomes are decided?
A slot resolves through a random number generator inside the machine, and the outcome is displayed on a screen. A table game resolves through physical events, cards dealt or a wheel spun, in front of the players. The mathematical structure is similar in that both are negative-expectation games, but the pace and the visibility of the process differ.
Are electronic versions of roulette and blackjack the same games as the table versions?
The rules are the same, and the house edge is the same when the rule set matches. What changes is the speed of play, the minimum bet, and the absence of a physical dealer in front of you. An electronic roulette wheel with a single zero has the same 37-pocket structure as a physical European wheel.
Why do some games have a printed RTP and others do not?
Machine games typically publish a theoretical return to player on the information panel because the game's return is fixed by its software. Table games state their rules and payout schedules instead, and the house edge is derived from those rules. Both describe the same long-run relationship between wagers and returns, just expressed from different directions.
