Roulette Review: 98.5% RTP
Roulette is InOut Games' entry into classic table games, offering a standard European-style wheel rather than the studio's usual crash or pick-and-climb mechanics. Players place bets on numbers, colors or number groups before the wheel spins and a ball settles into a pocket. SlotCatalog records the game's RTP at 98.5%, one of the highest figures across InOut Games' whole catalog. Here is how the wheel works, where to play it, and what that RTP means for the house edge on each bet type.

What Is Roulette?
Roulette is InOut Games' entry into classic table games, released on 10 October 2023 and offering a standard European-style wheel rather than the studio's usual crash or pick-and-climb mechanics. Players place bets on numbers, colors, or number groups before the wheel spins and a ball settles into a pocket.
Because it follows the familiar European layout, single zero, 37 pockets, the house edge and payout structure are the same well-known ratios found on any standard roulette table: 35 to 1 on a straight-up number, 2 to 1 on a dozen or column, and even money on outside bets like red/black or odd/even.
SlotCatalog records the game's RTP at 98.5%, one of the highest figures across InOut Games' whole catalog and above the 97 percent typical of many live-dealer roulette variants. As a fixed-odds table game rather than a volatility-driven slot, there is no single maximum win multiplier; the payout for any bet is set by its type, not by a jackpot-style cap.
In One Sentence
A standard European single-zero wheel with straight-up, split, dozen, column and outside bets, each carrying its own fixed payout ratio rather than a single house-quoted max win.
How to Play Roulette - Step by Step
Betting follows the standard European roulette layout. No difficulty levels, no bonus rounds, just bet placement and a spin.
Choose your chip value
Set a stake per chip based on the casino's table limits before placing any bets.
Place inside bets
Cover single numbers (straight-up) or small groups (splits, corners) for higher payouts at lower odds.
Place outside bets
Cover larger groups like red/black, odd/even, or high/low for lower payouts that land close to half the time.
Add dozens or columns
Bet on a third of the wheel for a middle-ground payout between inside and outside bets.
Watch the spin
Once bets close, the wheel spins and the ball drops until it settles into a numbered pocket.
Collect or adjust
Winning bets pay according to their fixed ratio. Adjust your bet spread for the next round based on your own bankroll plan, not on the previous result.
Demo mode runs on the same engine and the same 98.5% RTP. The only difference is virtual credits instead of real money.

One of the highest disclosed RTP figures in InOut Games' catalog, verified via SlotCatalog.

Roulette Glossary
The terms that come up most often when players discuss Roulette, explained with the game's real numbers.
- RTP
- 98.5% of total wagers are returned to players over the long run across all bet types combined, per SlotCatalog.
- House Edge
- The casino's built-in mathematical advantage; on a European single-zero wheel this works out to roughly 1.35% to 2.7% depending on the bet type.
- Straight-Up Bet
- A bet on a single number, paying 35 to 1 if it hits.
- Split Bet
- A bet covering two adjacent numbers on the table layout, paying 17 to 1.
- Dozens and Columns
- Bets covering 12 numbers each, paying 2 to 1.
- Outside Bets
- Bets covering 18 numbers such as red/black, odd/even or high/low, paying even money.
- European Wheel Format
- Single-zero wheel with 37 pockets, standard across most reputable online roulette titles.
- Payout Ratio
- The fixed multiple applied to a winning bet, set by bet type rather than by a single game-wide max win figure.
Roulette Demo - Try It for Free
Most casinos offering Roulette include a demo. Same 98.5% RTP, no registration, only virtual credits.
- Open the demo through any casino listed in the Where to Play section above.
- Place small outside bets like red/black for your first 15 to 20 spins.
- Track how often outside bets land versus straight-up numbers.
- Try a few dozens or column bets to see the middle-ground payout in action.
- Move to real money only once you are comfortable with the full betting map.
Roulette Strategy and Bankroll Management
Roulette has no strategy that changes the underlying house edge, but bankroll approaches can change how long your session lasts and how it feels to play.
Outside Bets Only
Stick to red/black, odd/even or high/low. Wins are smaller but land close to half the time, stretching your bankroll across the most spins.
Dozens Plus a Few Numbers
Split your stake between a dozen or column bet and two or three straight-up numbers for a mix of steady action and occasional bigger hits.
Heavy Straight-Up Coverage
Cover five to eight single numbers each spin, accepting that most spins lose in exchange for a large payout on a hit. Only play this with money you can fully afford to lose.
The shared lesson: decide your bet spread and cash-out target before the wheel spins, since no betting system changes the fixed 98.5% RTP over the long run.
Common Mistakes and How to Avoid Them
We looked at play patterns reported across roulette-focused player forums. The same handful of mistakes kept showing up.
| Mistake | What Happens | Fix |
|---|---|---|
| Doubling bets after a loss | Chasing losses with a Martingale-style approach that can quickly hit table limits | Set a fixed bet size or a strict loss limit for the session and stick to it |
| Ignoring the house edge difference between bet types | Assuming all bets carry the same risk when straight-up numbers carry far higher variance than outside bets | Learn the payout table in the glossary above before mixing bet types |
| Believing in number patterns | Thinking a string of low numbers means a high number is 'due' next | Each spin is independent of the last; the wheel has no memory |
| Betting with money set aside for essentials | Treating roulette sessions as a way to cover a bill or debt | Only play with disposable income, capped at a small percentage of monthly earnings |
Roulette App - iOS, Android, and APK
InOut Games does not publish a standalone Roulette app. Anything with that name in the App Store or Google Play is either a clone or a scam.
Safe
- Mobile websites at SlotsGem, Mostbet, 22Bet and Wazamba, all in-browser.
- Official casino apps, either from Google Play or an APK hosted on the operator's own domain.
- iPhone via Safari or the casino's own iOS app.
Avoid
- "Roulette Official APK" from unknown third-party sites, malware risk.
- TikTok and YouTube ads promising a "Roulette Predictor."
- Apps that run offline or promise to predict outcomes in advance.
Mobile vs desktop: same engine, same math, same 98.5% RTP.
Roulette vs Wheel Out and Mine Slot
Roulette is currently the only classic table game in InOut Games' catalog, so the closest comparison is against two other RNG titles from the same studio: Wheel Out and Mine Slot.
| Parameter | Roulette | Wheel Out | Mine Slot |
|---|---|---|---|
| Developer | InOut Games | InOut Games | InOut Games |
| Category | Table Games | Wheel | Mines |
| RTP | 98.5% | 96.5% | 96% |
| Mechanic | Bet placement + wheel spin | Single-launch modifier path | Reel spin feeding a mines grid |
| Max Win | Not officially disclosed | Not officially disclosed | Not officially disclosed |
| Volatility | Not applicable (fixed-odds) | Not officially disclosed | Not officially disclosed |
Bottom line: Roulette stands apart from Wheel Out and Mine Slot because its payouts are fixed by bet type rather than driven by a single volatility curve. It also currently posts the highest disclosed RTP anywhere in InOut Games' catalog, making it a reasonable pick for players who prefer predictable, well-understood table game math over slot-style variance.
Payouts, KYC, and Security
Roulette runs as a fixed-odds table game with no bonus rounds or hidden mechanics, so problems with the game engine itself are rare. Most friction that players report involves deposits, KYC checks or confusion about bet-type payouts rather than the wheel.
Payout Is Delayed or Stuck
Offshore casinos require KYC after your first win. SlotsGem and Mostbet usually clear it in 2 to 4 hours, 22Bet and Wazamba in 24 to 72 hours. Fix: upload your ID, a selfie and proof of address, a utility bill no older than 90 days, right after registering. Complaints go to Curacao eGaming or the MGA, both of which typically respond within 10 business days.
Payment Methods
Reliable options include Visa, Mastercard, Skrill, Neteller and cryptocurrencies. Crypto deposits in BTC, ETH or USDT are accepted at Mostbet and 22Bet. Availability of any specific method still depends on your country and the casino you choose.
Security, Pros and Cons
Highest Disclosed RTP in the Catalog
98.5% RTP beats every other publicly listed InOut Games title, per SlotCatalog.
Familiar, Well-Understood Math
Standard European wheel payouts mean players can look up the exact house edge for any bet type.
No Hidden Bonus Mechanics
What you see on the table is the entire game, with no bonus buy or feature gating.
No Big Multiplier Moments
Fixed-odds payouts mean there is no jackpot-style max win to chase.
Higher Wagering Contribution Restrictions
Table games like this often count only partially toward casino bonus wagering requirements.
Roulette Reviews - Players Share Their Results
Feedback gathered from player forums and our own testing across SlotsGem, Mostbet, 22Bet and Wazamba.
"Clean, no-nonsense roulette table. I mostly play outside bets and it behaves exactly like the odds say it should over a long session. Withdrawal from 22Bet took about half a day."
"Nice to have a proper table game in the InOut Games lineup instead of another crash clone. Only complaint is the bonus wagering contribution for table games is lower than for slots, which caught me off guard the first time."
"Straight-up numbers are brutal long term but that's roulette for you. I stick to dozens now and the sessions last a lot longer. Support at Wazamba answered a KYC question within the hour."
"Wheel physics feel fair, no weird patterns I could spot after a few hundred spins. Wish the interface showed the running house edge for whatever bet combo you've placed."
"Higher RTP than most roulette I've tried elsewhere, and SlotsGem's welcome bonus made the first sessions basically free to test out."
Play Responsibly - 18+
Roulette's fast round pace and wide range of bet sizes make it easy to lose track of how much you have wagered across a session, especially when mixing outside bets with occasional straight-up numbers.
Practical Rules
- Set a daily or weekly deposit limit in the casino.
- Never play with money set aside for rent, food or debt payments.
- Do not try to "win back" losses the next day.
- Decide your cash-out target before the round starts, not while it is running.
- Calculate your net balance at the end of each month; withdraw when you're up, pause when you're down.
