A bankroll is a budget you set for playing roulette. Roulette bankroll plays a very important role in protecting you from losing more than you can afford.

Biased Wheel

A biased wheel is a defective roulette wheel that favors one or more numbers. It isn’t necessarily a rigged one, but it is faulty and doesn’t produce random results.

This terms isn’t applicable to RNG roulettes, but you may encounter a biased wheel at a brick-and-mortar venue or while enjoy UK casino live games.

Call Bets

Call bets are specific bets that cover entire sections of the roulette wheel. They are also known as French bets.

There are three fixed types of called bets (Voisins du Zéro, Tiers du Cylindre, Orphelins) and two variable call bets (neighbors and finals).

Cold Numbers

Cold numbers are numbers that haven’t come up for a longer period. There are no precise criteria for determining the timeframe for cold numbers, but many players agree that it should be at least 37 spins.

Cold Table

A cold table is any roulette table where most, if not all, players have been losing.

No Action

The croupier can call no action, meaning the casino won’t cover a specific bet. In some cases, this term can also mean that all bets for the spin are canceled and that the betting actions have to be restarted.

Outside Bets

Outside bets are the second type of bets in roulette. Contrary to inside bets, outside bets combine larger groups of numbers.

Therefore, they offer much smaller payouts but more significant winning odds. Some common outside bets are odd/even and red/black, among others.


The pocket is the numbered compartment on the roulette wheel. European roulette includes 37 pockets, numbered from 0 to 36, and the American roulette version has 38 pockets, as it also includes a 00 pocket.

Popular examples of progression betting systems include the Martingale system, Fibonacci, and d’Alembert.


A stack is a common term that refers to a pile of chips. Keeping your chips in stacks, ideally of 10 or 20 chips, speeds up the game, as it helps the croupier handle the chips and payouts more quickly.

The simplest bet in roulette. A straight up is a bet placed on any one number. It pays 35:1 and is the most rewarding, but also the riskiest bet to place in roulette.
