What is Roulette?
Roulette has been a casino staple for over 200 years and the core concept hasn't changed: a croupier spins a wheel, drops a ball, and players win or lose based on where it lands. The wheel has numbered pockets from 0 to 36 — 37 in total on the European version — and the betting table maps to those numbers in a variety of ways.
European Roulette (the version on Spinomera) has a single green zero pocket. That single zero is where the house edge comes from — it's the one number that doesn't pay out on red/black, odd/even, or high/low bets. Remove it and the game would be perfectly fair. With it, the RTP sits at 97.3%.
What makes Roulette interesting is the sheer range of bets available. You can bet on a single number for a 36× payout, or spread across red/black for a near-even chance. Most players mix inside bets (specific numbers) with outside bets (broad categories) to balance risk and reward.
European vs American: American Roulette adds a double-zero (00), dropping the RTP to ~94.7%. Spinomera uses European only — the better deal for players.
How to play, step by step
- Set your bet amount — choose how many chips to place per bet slot.
- Place your bets — click any position on the layout. You can place multiple bets simultaneously; they're all resolved on the same spin.
- Spin the wheel — once you're happy with your bets, spin. The ball drops and the wheel determines the winning number.
- Collect winnings — all winning bets pay out automatically. Losing bets are cleared. Winning bets stay on the table ready for the next round if you choose.
You can place as many different bets as you like on a single spin. A 1,000-chip bet on red and a 50-chip straight-up bet on number 17 both ride the same spin independently.
What the numbers mean
The 37 pockets are numbered 0–36. Zero is green. Of 1–36: 18 are red (1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36) and 18 are black. The numbers are split into three columns and three dozens, which matters for column and dozen bets.

Full payout table
| Bet type | Covers | Payout |
|---|---|---|
| Straight up | 1 number | 36× |
| Red / Black | 18 numbers | 2× |
| Odd / Even | 18 numbers | 2× |
| Low (1–18) | 18 numbers | 2× |
| High (19–36) | 18 numbers | 2× |
| Dozen | 12 numbers | 3× |
| Column | 12 numbers | 3× |
All payouts are total return — a 2× payout on a 100-chip bet means you get back 200 chips (your 100 back plus 100 profit).
Strategy tips
Spread your bets
Combine an outside bet (red/black) with a small straight-up bet on a favourite number. The outside bet keeps you in the game; the straight-up bet chases the big win.
Understand the house edge
Every bet has the same 2.7% house edge on a European wheel, regardless of bet type. No bet is mathematically "better" than another.
Avoid progressive systems
Martingale (doubling after losses) and similar systems don't change the math. They accelerate variance and can wipe a balance faster.
Cover more of the wheel
If you want more action, bet on both a dozen and a column simultaneously. You'll cover roughly 20 numbers for a 3× return.
Why does zero hurt outside bets?
Outside bets (red/black, odd/even, high/low) cover exactly 18 of the 37 numbers. Zero is the 37th — it belongs to no outside bet category. When it lands, all outside bets lose. That's where the house edge lives. On American Roulette there are two zeros (0 and 00), doubling the damage.
FAQ
Can I bet on zero?
Yes — zero is treated like any other number. You can place a straight-up bet on 0 and it pays 36× if the ball lands there.
Can I place multiple bets on the same spin?
Absolutely. You can stack as many different bets as you like. Each is settled independently — a win on red doesn't affect your straight-up bet on 5.
What's the maximum I can bet?
Each individual bet slot has a maximum of 5,000 chips, but there's no limit to how many different bets you place per spin.
Is there a "best" number to bet on?
No. Every number has exactly the same probability of winning (1 in 37) on a fair wheel. "Hot" or "cold" numbers from previous spins don't affect future outcomes.
What's the difference between a column and a dozen?
A dozen groups numbers numerically (1–12, 13–24, 25–36). A column groups them by their physical position in the three vertical columns on the betting layout — the numbers in each column aren't consecutive.
