Roulette Tables: European and American Layouts Compared

Compare European and American roulette layouts by their pockets, number patterns and stated odds, so you can recognise the table design before choosing.

European and American roulette layouts differ by one pocket, and that extra pocket changes the stated odds on every standard bet. European roulette has pockets numbered 1 to 36 plus a single zero; American roulette adds a double zero. The difference is easy to miss on the felt, but it affects how often a winning number or group of numbers appears in the wheel’s full set of possibilities.

What does each roulette layout contain?

A roulette wheel is divided into numbered pockets, while the table layout gives players a place to select numbers and betting groups. The two common versions share the numbers 1 through 36, alternating between red and black, and a green zero pocket. Their central distinction is whether the wheel has one green pocket or two.

  • European roulette: 37 pockets: numbers 1 to 36 and one 0.
  • American roulette: 38 pockets: numbers 1 to 36, one 0 and one 00.

On a European wheel, the single zero sits among the numbered pockets in the wheel’s sequence. On an American wheel, the 0 and 00 are separate pockets, usually placed apart in the sequence. The felt reflects the same distinction: European layouts show a single zero betting space, while American layouts display both 0 and 00.

Do not confuse the wheel’s numbered sequence with the arrangement of numbers on the betting layout. The betting grid groups numbers into rows and columns; the wheel orders pockets around its rim. The colours and betting groups look familiar across both versions, which is why checking the green spaces is a more reliable way to identify the layout than relying on the table’s overall appearance.

How does the extra pocket change stated odds?

A roulette bet wins when the ball lands in a pocket covered by that bet. The number of winning pockets may be the same on either version, but the total number of pockets differs. That changes the stated chance of a win.

For a single-number bet, one pocket wins. On a European wheel, that is one winning pocket among 37; on an American wheel, it is one among 38. For a bet on red, 18 pockets win on either layout, but the total remains 37 or 38. The red spaces have not changed; the extra green pocket is another possible result that does not pay a red bet.

In the standard roulette payout schedule, a straight-up bet pays 35 to 1. That payout is the same on both layouts, even though the chance of hitting the chosen number is lower on the American wheel. The gap between the stated payout and the chance of winning is one reason the extra pocket matters to the game’s house economics. This comparison is about the wheel’s design and standard odds, not a claim that any particular spin predicts the next one.

For example, imagine a player considering a straight-up bet on 17. The player checks the wheel and sees one 17 pocket on either layout, then notices that the American version also has 00. The expected observable result is a clear comparison: the bet still covers one pocket, but that pocket is one of 38 outcomes rather than one of 37.

Which bets are affected by the layout?

The extra pocket changes the chance for every standard bet that covers numbered pockets, because it adds an outcome outside those numbers. The practical size of the difference depends on how many pockets the bet covers.

  • Straight-up: covers one number, so one pocket wins.
  • Split: covers two adjacent numbers, so two pockets win.
  • Street: covers a row of three numbers.
  • Corner: covers four numbers meeting at a grid corner.
  • Dozen or column: covers 12 numbers.
  • Outside bets: red or black, odd or even, and high or low each cover 18 numbered pockets.

For any of these bets, compare the number of covered pockets with the total: 37 for European roulette or 38 for American roulette. A bet covering 12 numbers, for instance, still covers 12 on both layouts, but those 12 represent a smaller share of the American wheel’s possible outcomes. The same logic applies to outside bets, despite their broad coverage.

The zero pockets also explain why red and black do not behave like a simple split of all possible outcomes. There are 18 red and 18 black numbered pockets, but the green zero or zeros belong to neither colour. Those green pockets are not red or black outcomes, even if a table’s design places them visually near the numbered grid.

How do the layouts compare on the table?

The number pattern is the fastest visual clue. Look for a single green 0 to identify a European layout, or a green 0 and 00 to identify an American one. The wheel and betting grid should agree; if the display is unclear, check the game’s rules or table information before placing a bet.

Other details can vary by casino or game version, so avoid treating every table labelled “European” or “American” as identical in every respect. The pocket count is the defining comparison here. If the stated payouts or special rules matter to your decision, read the posted rules rather than inferring them from the layout alone.

A digital game can show the layout on screen rather than on felt. The same recognition method applies: count the green pockets in the wheel graphic or betting area. A single green zero indicates the 37-pocket format; a displayed 0 and 00 indicate the 38-pocket format.

Which roulette layout should you choose?

For a player choosing between standard tables, the European layout has fewer pockets and therefore more favourable stated odds for the same covered numbers and standard payouts. The American layout gives the same familiar betting groups but includes an additional losing outcome for bets that do not cover 00.

Who might prefer each option? Someone comparing the basic mathematics will generally favour the single-zero layout. Someone joining a particular table for its social setting, its location or its available game format may accept the double-zero version, provided they understand the difference. Neither layout makes a spin predictable, and a past result does not change the pocket count on the next spin.

A clear way to choose is to check three things before betting:

  1. Count the green pockets: one zero or both zero and double zero.
  2. Confirm the displayed payout for the bet you intend to make.
  3. Compare the number of pockets covered with the wheel’s total pocket count.

If the goal is to compare the standard odds with as little extra complexity as possible, look for a single-zero European table. If only an American table is available, the same betting choices remain, but the stated chance of a win is lower for an identical bet under the usual payout schedule.

What do players commonly ask about roulette layouts?

Is European roulette the same as single-zero roulette?

In the standard comparison, yes: European roulette has one green zero and 37 pockets in total. Always use the displayed wheel and rules to identify the specific game in front of you.

Does American roulette always have 00?

The standard American layout includes both 0 and 00, making 38 pockets. If a game uses a different layout or special rules, its own description is the reliable guide.

Does 00 change a bet’s payout?

Under the standard payout schedule, the listed payout for a given bet is the same on both layouts. The extra pocket changes the chance of winning, not that standard payout.

Are red and black equally likely on both wheels?

Each wheel has 18 red and 18 black pockets. The added green pocket on the American wheel makes either colour a smaller share of all possible outcomes than on the single-zero layout.

What is the simplest way to compare the two?

Count the pockets first, then compare the number your bet covers with the total number the wheel can produce. European roulette has 37 pockets; American roulette has 38 because of 00. That single design difference is the reason the stated odds shift, even when the table’s familiar red, black and numbered bets look much the same.

When you compare roulette tables, the most useful question is not which one looks more inviting, but whether the extra green pocket is part of the game you are considering. Recognising that detail lets you read the layout before the ball is in motion.
