Online roulette: variants, bets and tables at Casino King
Roulette is the casino game you grasp fastest and one of the easiest to play badly. The rules fit into two sentences, but the choice of table, the type of bet and the reading of the layout make a considerable difference across a full session.
This page runs through the variants available, what each one actually costs the player, the families of bets and what the much-discussed strategies are really worth. Casino King's tables run without a dealer, in line with our B+ licence.
A round in three movements
Every round follows the same sequence. You place your chips on the layout during the betting window, in as many spots as you like. The window closes, the ball is launched, and it eventually settles into a numbered pocket.
Everything covering that number is paid, the rest is swept away. There is no turn order and no decision left to make once the ball is rolling: roulette is a game of placement, not of judgement.
The layout also displays the history of recent numbers. Useful for spotting hot streaks, people often say — in reality of no predictive value whatsoever, since every round starts from scratch.
European, French, American: the variant decides everything
This is the only choice that mathematically affects your odds, and it is made before you even bet.
European roulette carries 37 pockets, from 0 to 36. A single zero, therefore a house edge of 2.70%. That is the reference point, and the one to reach for by default.
American roulette adds a double zero and moves to 38 pockets. The house edge climbs to 5.26%, almost double. At equal presentation and equal stake, the American version costs twice as much over time. That gap does not show over ten spins; it shows over a thousand.
French roulette uses the European wheel but adds a rule that transforms even-money bets: when the zero lands, your stake is either halved back to you or held for the following spin. The edge then falls to 1.35% on those specific bets, making it the most favourable variant in the casino.
The two families of bets
The layout divides into two zones whose logic differs entirely.
Inside bets go on the numbers themselves: a straight-up pays 35 to 1, a split covers two numbers for 17 to 1, a corner covers four for 8 to 1. Rare wins, high amounts, sessions full of sharp swings.
Outside bets cover broad sections of the layout: red or black, odd or even, low or high pay 1 to 1, while dozens and columns pay 2 to 1. Frequent wins, modest amounts, a budget that lasts longer.
A point often missed: the house edge is identical across all those bets, with the sole exception of even-money bets on French roulette. Choosing a straight-up over red therefore changes nothing about the expectation, only the volatility of your session.
The automated tables in the catalogue
Our roulettes run without a dealer. Some are built around an authentic wheel housed in a recording room, set spinning by a mechanism and permanently on camera; others are generated entirely by software.
Among the filmed tables, Pragmatic Play supplies Auto Roulette and Auto Mega Roulette, the latter adding multipliers drawn at random on certain numbers before the spin. Stakelogic rounds out the range with classic and VIP versions distinguished by their stake brackets.
How those wheels are launched, filmed and read by sensors is set out in full on the live casino page, which covers the format as a whole.
The virtual and themed versions
Amusnet offers a fully animated range, where the wheel is modelled in three dimensions and the outcome is settled by an independently certified randomiser. The benefit is twofold: lower minimum stakes, and presentations impossible to build physically — a stylised Monaco, a space setting, a Vegas atmosphere.
Gaming1 contributes a vertical roulette designed for the phone format, and a version inspired by a television show. Galaxsys signs off on a version with an accelerated rhythm.
Be careful, though, not to confuse presentation with playing conditions. A roulette with a spectacular setting but a double zero still costs twice as much as a plain European one. Check the number of pockets before letting the staging win you over.
What a table's reliability rests on
The question comes up often, and it is a fair one. On a physical wheel, the answer is visible: the equipment is calibrated and audited like that of an arcade, and the ball's path depends on mechanics, not on a calculation.
On a modelled table, the result comes from a randomiser certified by an independent laboratory and audited regularly. The payouts displayed correspond exactly to the odds of each bet type, and that can be checked: a straight-up pays 35 to 1 for a one-in-37 chance.
That slight gap between payout and true probability is precisely the house edge. It is not hidden, it is mathematical, and it appears in every table's help screen.
What the strategies are really worth
Let us be blunt: no method alters the house edge. The wheel has no memory, and every spin is independent of the last.
The martingale, which doubles the stake after each loss, works right up until it fails — and it always fails, either because the table ceiling is reached or because the budget runs dry. Seven consecutive losses on red-black, which happens more often than people imagine, require a stake of 128 times the original unit to recover a single one.
Gentler progressions such as the d'Alembert or the Paroli do no better mathematically. They do, however, have a genuine merit: they impose betting discipline and prevent impulsive decisions. That is their only real use, and it is not a trivial one.
Setting your stake before you start
Roulette strings rounds together quickly, especially in the automated version where nothing waits for anyone. A budget therefore goes down faster than you would expect.
The simplest benchmark is to set your unit stake against your total budget: betting 1% of what you have set aside leaves you around a hundred spins, enough for a proper session. Betting 10% leaves you ten.
Each table shows its bracket before you sit down, and nothing stops you moving between tables mid-session if yours no longer matches what you meant to commit.
Getting your bearings before you stake
The modelled versions launch in demonstration mode, on a play-money balance and without opening an account. You can run as many spins as you like: the wheel, the payouts and the layout are rigorously identical to the paid version.
It is the best way to grasp the difference between a split and a corner, or to see how quickly a theoretical budget shrinks depending on the bet type chosen. Half an hour in demo teaches more than ten strategy articles.
Tables with a physical wheel are the exception: real equipment is turning in a studio, so they are played for real money only.
Getting to grips with the layout
The roulette layout intimidates more than it should. A few spins are enough to locate where the dozens sit, where the columns begin, and how to place a split precisely between two numbers without catching the wrong box.
On a phone the display rotates and the boxes grow — a useful precaution, since a misplaced chip cannot be taken back once the betting window has closed.
A Belgian framework that protects you
Casino King operates under licence B+19763, granted by the Belgian Gaming Commission. That means certified tables, a minimum age of 21 with no exemption, and deposit ceilings you set yourself from your profile.
That last point deserves particular attention with roulette. It is a game where rounds pass quickly and where nothing imposes a break: a deposit ceiling and a time limit are more useful here than elsewhere.
When you cash out, the money reaches your bank in seconds thanks to instant payout. And if the wheel no longer holds you, Casino King also offers card games, alongside the full catalogue reachable from all games.
Frequently asked questions
French on even-money bets, with a 1.35% house edge. Failing that, European with its single zero, at 2.70%. American, at 5.26%, is best avoided.
None at all. The B+ licence we hold covers automated games: the wheel is either set in motion by a mechanical system or recreated on screen.
No. It produces small frequent wins followed by one heavy loss that wipes everything out, once the table ceiling or the budget is reached.
The straight-up, at 35 to 1. But the house edge there is identical to red-black: only the volatility changes, not the expectation.
On the modelled versions, yes: play-money balance, no registration required. On tables with a physical wheel, no, as real equipment is running.
A table where certain numbers see their payout raised before the spin, as on Auto Mega Roulette. Potential wins climb, the odds stay unchanged.
37 on the European and French versions, from 0 to 36. The American carries 38, with an extra double zero.
Yes, provided the site holds a Belgian licence. Ours carries the number B+19763.
