Essential Roulette Terms Every Player Should Learn
Roulette has a funny way of making simple bets sound complicated. Put a chip on one number and it's a straight-up. Put it between two numbers and suddenly it's a split. Move the same chip to the corner of four boxes and, conveniently enough, you've made a corner bet.
You don't need a roulette dictionary beside you at the table. But knowing the common terms makes the layout much easier to read, especially when words like inside, street, dozen, or house edge start coming up.
Inside and Outside Bets
This is the easiest place to start because almost every roulette bet falls into one of these two groups.
Inside bets are made on the numbered grid. They cover fewer numbers and usually come with larger payouts. Straight-ups, splits, streets, corners, and six-line bets all belong here.
Outside bets sit around that grid. Red/black, odd/even, high/low, dozens, and columns are the ones you'll see most often. They cover more numbers, so they hit more often but pay less.
There's nothing more mysterious behind the names. "Inside" and "outside" really do describe where the chips go on the layout.
Straight-Up, Split, Street and Corner
These four terms cover most of the basic inside bets.
A straight-up is one number. Put a chip directly on 17 and that's it. A win pays 35:1.
A split covers two numbers next to each other on the layout. The chip sits on the line between them and the payout is 17:1.
A street covers a horizontal row of three numbers, such as 10, 11, and 12. It pays 11:1.
Then there's the corner, which covers four numbers meeting at one point. Place the chip where 10, 11, 13, and 14 meet, for example, and all four are covered. A winning corner pays 8:1. These standard definitions and payouts are the same ones used in roulette references from Roulette 77 and Wizard of Odds.

Once those names click, a big part of the table stops looking so busy.
What Does Even-Money Mean?
You'll hear red/black, odd/even, and high/low called even-money bets.
That doesn't mean the chance of winning is exactly 50%. It describes the payout: bet $10 and a win produces $10 in profit.
The zeros are what spoil the true 50/50 split. On American roulette, red covers 18 pockets but there are 38 possible results because 0 and 00 are also on the wheel. Red therefore wins 47.37% of the time rather than 50%. Standard American roulette figures confirm the same probability for the other even-money bets.
So "even money" is a payout term, not a promise about the odds.
House Edge and RTP
These two terms sound technical, but they're really describing opposite sides of the same number.
House edge is the mathematical advantage built into the game. Standard American roulette has a 5.26% house edge on most bets. European roulette, with only one zero, sits at 2.70%.
RTP means return to player. American roulette's standard 5.26% house edge corresponds to a theoretical RTP of 94.74%.
Neither number predicts a short session. They're long-run figures based on a huge amount of play.
Roulette 77 also uses RTP in its guides at roulette77.us. If you see 94.74% for American roulette, that’s simply the other side of its 5.26% house edge.
The Wheel and the Layout Aren't the Same Thing
This one sounds obvious until someone says "the number is next to 17" and you realize they could mean two completely different things.
The wheel is the spinning part where the ball lands. The layout is the betting area where chips are placed.
Numbers that sit next to each other on the layout aren't necessarily neighbors on the wheel. On an American wheel, for example, the sequence around the rim follows its own order rather than running 1, 2, 3, 4 and so on.
That's why a neighbor bet refers to positions on the wheel, not simply boxes touching each other on the table.
A Few Dealer Terms Are Worth Knowing Too
Live roulette comes with a few words you won't see as often in a digital game:
Croupier - the dealer running the roulette table.
No more bets - betting is closed for the current spin.
Stake - the amount of money placed on a bet.
You may also hear racetrack. Despite the name, it has nothing to do with horse racing. It's an oval-shaped betting area used for wagers based on sections of the wheel rather than the normal number grid. Sector bets such as Voisins du Zéro, Tiers du Cylindre, and Orphelins can be placed through it on tables that offer them.
Those names are more common around European and French roulette, so there's no reason to memorize them before learning the basic table.
The Names Get Easier Once You See the Chips
Roulette terminology can look like a lot when it's written in a glossary. At an actual table, most of it is pretty visual. One chip on a number is a straight-up. Between two numbers is a split. Four numbers meeting around a chip make a corner.
The same goes for the bigger terms. Inside and outside describe parts of the table. RTP and house edge describe the math behind it.
Learn the handful of words that come up all the time and the rest can wait. Nobody needs to memorize Tiers du Cylindre before they know what a split is.
