12 bang Roulette — Complete Table Betting Guide and Strategy
Roulette is a classic casino game where a spinning wheel and a small ball decide whether you win or lose. At 12 bang, you can play at both digital and live dealer tables. This guide covers roulette rules, bet types, house edge and starting strategies in plain English.
How a Round Works
A roulette round begins with the betting phase — the dealer announces it, and players place chips on the designated areas of the table. Once the betting window closes, the dealer spins the wheel and releases the ball in the opposite direction. As the wheel slows, the ball drops into a numbered pocket — that number and its colour (red or black) determine who wins.
A European roulette wheel has numbers 1 to 36 and one green zero (0) — 37 pockets in total. American roulette adds an extra double zero (00), making 38 pockets. French roulette also has 37 pockets, but special rules such as "La Partage" work in the player's favour.
After winning bets are paid out, all chips are cleared and a new round begins. The whole process happens in real time at a live table, while in the digital version a software algorithm generates a random number.
Bet Types and Payouts
In roulette, bets fall into two main categories — inside bets (on specific numbers on the wheel) and outside bets (on larger groups). The main types are summarised below.
| Bet Name | Where It Is Placed | Payout Ratio | Win Probability (European) |
|---|---|---|---|
| Straight Up | On a single number | 35 to 1 | 2.7% |
| Split | On the line between two adjacent numbers | 17 to 1 | 5.4% |
| Street | On a row of three numbers | 11 to 1 | 8.1% |
| Corner | On the corner of four numbers | 8 to 1 | 10.8% |
| Line | On two adjacent rows (6 numbers) | 5 to 1 | 16.2% |
| Red / Black | Outside — on the colour box | 1 to 1 (even money) | 48.6% |
| Odd / Even | Outside — odd/even | 1 to 1 | 48.6% |
| Low / High | Outside — 1–18 or 19–36 | 1 to 1 | 48.6% |
| Dozen | Three groups of 12 numbers | 2 to 1 | 32.4% |
| Column | On the three columns of the table | 2 to 1 | 32.4% |
Note: when the ball lands on zero (0), all outside bets generally lose, which is what creates the casino's house edge.
House Edge — How the Casino Stays Ahead
The house edge in roulette is the small mathematical advantage the casino retains on every bet. In European roulette, with only one zero, the house edge is around 2.7%. In the American version, with two zeros (0 and 00), the house edge rises to about 5.3% — meaning on average, over the long run, about ৳5.3 out of every ৳100 wagered goes to the casino.
In French roulette, the "La Partage" rule works in the player's favour — if the ball lands on zero, half of any even-money bet is returned, bringing the effective house edge down to just 1.35%. This makes French roulette comparatively better for players who spend most of their time on outside bets.
Keep in mind that the house edge is a long-term statistical concept — anyone can win in one or a few rounds. No strategy in a casino can eliminate the house edge entirely, but choosing your bets carefully can reduce your rate of loss.
Useful Strategies for Beginners
Choose a European Table
Start with European roulette. One zero means a lower house edge — your money has a much better chance of lasting longer compared to an American table.
Start with Outside Bets
Red/black or odd/even bets have close to a 50% chance of winning and the payouts are easy to understand. Inside bets offer higher returns, but the risk is much greater.
Set Your Budget Beforehand
Decide how much you are willing to spend before starting a session. Once you reach that limit, stop — chasing losses with more bets almost always makes things worse.
Be Careful with the Martingale Method
The Martingale method means doubling your bet after every loss. While it sounds appealing in theory, a string of consecutive losses can wipe out your entire balance — especially when you hit the table's maximum limit.
Forget the Previous Round
Every round is completely independent — ten reds in a row does not mean black is due next. This misconception is where most big losses come from.
Live Dealer vs Digital Roulette
Live Dealer Roulette
- A professional dealer spins the wheel in a real studio — visible via video stream
- You can chat with the dealer in the chat box, giving a social feel
- Tables from various studios including Evolution and Pragmatic Play Live are available
- Slower pace — depends on the dealer's announcement of the betting window
- A good internet connection makes the experience much better
Digital (RNG) Roulette
- Runs on a software random number generator — no dealer
- Play at your own pace — faster rounds, more hands per hour
- Works fine even with a slower internet connection
- Various variants available — mini roulette, multi-wheel versions and more
- No live social feel
Which One Should You Choose?
The real-environment feel of live roulette is hard to replicate in the digital version. However, for those new to 12 bang, the digital version lets you learn at your own pace without time pressure.
In 12 bang, go to the live casino section of 12 bang Casino to find various types of roulette tables — classic European, speed roulette, auto-roulette and several others.
The same quality experience is available through the app as well. Apps are available for both Android and iOS — visit the 12 bang App page for details.
Table Limits — From Low Stakes to High Stakes
Every roulette table has a minimum and maximum bet limit, which varies by table. Digital roulette generally has a very low minimum bet — meaning new players can start with a small amount and learn the rules without much risk.
Live dealer tables usually have a slightly higher minimum, since there are real studio operating costs involved. However, VIP and high-stakes tables are also available where experienced players can place larger bets.
Digital Table
Ideal for beginners — very low minimum bet, play at your own pace, and choose from multiple variants.
Standard Live Table
Mid-range limit table — direct experience with a dealer, popular among regular players.
VIP Live Table
For more experienced players interested in higher stakes — the maximum limit here is significantly higher.
Speed / Auto Roulette
Faster rounds allow more hands per hour — however, the bet limits are the same as standard tables.

Popular Roulette Variants
Beyond classic European, there are several roulette variants available in the casino section of 12 bang. In Lightning Roulette, random numbers receive extra multipliers, which can significantly increase the maximum payout on straight up bets.
In Double Ball Roulette, two balls spin at the same time, resulting in a different payout structure for certain bets. Immersive Roulette shows the wheel and ball movement in high-definition close-up.
