Online Roulette Rules and Odds Explained

If you’ve ever watched a roulette wheel spin, you’ll know it’s hard to look away. It’s elegant. It’s fast. It’s full of possibility. In Singapore, this classic game has been gaining serious traction, thanks to its smooth gameplay and koi-like calm that hides streaks of fiery red and fortune-filled gold.

Here’s a straightforward guide to help you read the table, know the odds, and make every spin count.

How Roulette Works (in a Nutshell)

You’ve got a spinning wheel with numbered slots—0 to 36.

Each number is either red or black (except for the green zero). You place your bet before the spin, guessing where the ball might land. You can bet on a single number (say, number 8), a range (like 1–18), a colour (red/gold or black), or even odd/even.

In RNG (random number generator) roulette, the spin happens instantly with digital software. In Live Roulette, a real dealer spins the wheel while players watch from their screens. Both options are popular among Singaporeans—some prefer the speed of RNG, while others find Live Roulette more immersive, like watching koi glide through a golden pond.

Types of Roulette Bets: What You Can Wager On

Here’s a quick breakdown of the bets you’ll see on the table:

Inside Bets (more risk, higher payout)

Straight up: Bet on a single number. Pays 35:1.
Split: Bet on two numbers side-by-side. Pays 17:1.
Street: Bet on a row of three. Pays 11:1.
Corner: Four numbers in a square. Pays 8:1.
Line: Six numbers (two rows). Pays 5:1.

Outside Bets (better odds, smaller payout)

Red or Black: Pick a colour. Pays 1:1.
Odd or Even: Bet on number type. Pays 1:1.
High or Low: 1–18 or 19–36. Pays 1:1.
Dozens: 1–12, 13–24, or 25–36. Pays 2:1.
Columns: Vertically arranged sets of 12 numbers. Pays 2:1.

What Are the Odds in Roulette?

Not all roulette tables offer the same odds, and this matters.

Here’s a breakdown of the most common versions:

Roulette Type	Zeroes	House Edge
European	1 (0)	2.7%
American	2 (0, 00)	5.26%
French	1 (0) + La Partage	~1.35%

Some quick bet odds:

Single number: 2.7% chance of winning (but pays 35:1)
Red/Black or Odd/Even: ~48.6% chance (pays 1:1)

Reminder: the green zero is a wildcard—it causes all outside bets to lose. That’s why many local players stick to European or French versions, especially when playing with real money.

How a Roulette Round Flows

Each round follows a simple pattern:

You place your chips on your chosen numbers or colours.
A dealer (or software) announces “no more bets.”
The wheel spins. The ball bounces, dances, then lands.
Results appear on screen, and payouts are made instantly.

In Live Roulette, the dealer might interact with you. In RNG, it’s all about speed and control.

Many Singaporean players bring small rituals to each spin—betting on lucky numbers like 8, 18, or 28. Others avoid 4 (a number linked with bad luck in Mandarin). There’s no right way to play—but knowing the flow helps you stay confident.
