Roulette pays the same flat price on nearly every chip, which makes it the easiest game in the room to rule on. On a one-zero wheel the ball has 37 pockets to pick from, and the layout lets you choose how many of them to cover. Cover more and you win more often for less. The arithmetic behind the payouts barely changes, so the real decision is how bumpy you want the ride.

Roulette bets and what each one covers

Payouts assume a single-zero wheel. The last column shows why inside and outside bets cost the same on average.

The rule: the wheel has 37 pockets and the payouts are worked for 36, so the missing pocket is the charge. The call: on a single-zero wheel, no chip beats another on price. Why: multiply each bet’s chance of winning by its full payout and the answer is 97.30% every time.

Two wheel rules move the figure. A second zero raises the standard bets to 5.26%. A French-rules table gives back half an even-money stake whenever zero hits, dropping that bet to 1.35%, so look for that wording in the help panel if you favour the outside.

Inside and outside: the choice that is left

With price off the table, your call is about variance. A straight-up bet at 35 to 1 wins about once every 37 spins, and long dry spells are the job description. A red bet wins nearly half the time and rarely pays much. Choose based on how a run of losses would affect your budget, then stake accordingly; house edge across the live tables shows how this compares to other games.

Lightning Roulette: what the multipliers actually cost

Lightning Roulette is an Evolution game, and the studio’s Roulette card in the lobby’s list is one place it could sit. Each round, a random set of numbers is struck and gets a multiplier applied to any Straight Up bet on them.

Here is the ruling on the trade. To fund the multipliers, a plain Straight Up win pays below the usual 35 to 1, so most spins pay you less than the table above in exchange for rare, larger hits. The panel in that game prints the plain payout and the multiplier range; read those figures rather than assuming the 2.70% carries over.

Roulette tables named in the lobby’s catalogue

The names listed include European Roulette under Sexy, Jili Game, KingMidas and V8; Roulette and Site Roulette under DG; Ultra Roulette C and Roulette D under SA Gaming; Premium European Roulette and others under Playtech; and the Evolution card above, explained on the Evolution gaming page. The lane list does not mark which of these use a live wheel, so check for a croupier once the table opens.

How to Get Started

  1. Check how many zeros the wheel has

    One zero gives 37 pockets; two give 38. The second zero raises the cost of every chip on the layout, so read the wheel first.

  2. Pick a bet by how you want to lose

    All the single-zero bets cost the same on average. Choose between rarer, larger wins and frequent, smaller ones based on your budget and patience.

  3. Read the panel on any multiplier table

    Lightning-style tables reprice the straight-up bet to pay for their multipliers. Find the plain payout and the multiplier range in the help panel before betting.

Questions sent to the referee

What is the house edge on roulette?

On one zero, 2.70% on every bet, because the wheel has 37 pockets and payouts are worked for 36. On a double-zero wheel it rises to 5.26%.

How does Lightning Roulette pay?

Each round, random numbers get a multiplier that applies to a winning Straight Up bet. To fund that, a plain straight-up win pays less than the usual 35 to 1. The table's help panel prints both figures.

Inside or outside bets: which is safer?

Outside bets win more often and pay less, inside bets the reverse. On one zero, the average cost is 2.70% either way, so safety here just means a smoother ride, not better odds.
