Online Casino Terms You Should Know

Playing at an online casino can be exhilarating. The adrenaline rush that comes from spinning the reels or playing a card game makes the whole experience wholesome.

However, for any new player, some casino lingo can sound intimidating, and make it a challenge for them to keep up. Understanding some of these terms before heading to an online casino can make the whole experience easier and more exciting. Here are some of the most online casino terms that you should know.


A bankroll refers to the funds a player maintains in the casino for gambling. It is the total amount a player is willing to risk at an online casino. Professional gamblers consider their bankroll as the total amount they use for work.

Wagering Requirements

These are the playthrough requirements that a casino applies to a promotion for players to meet before they can withdraw any winnings generated from the promotion/bonus. They are a specified number, such as x35, meaning that players need to wager their bonus amount 35 times before they can cash out any winnings from the bonus amount.

Return to Player (RTP) Percentage

It is the amount expected to be paid back to the players by the casino over time, which is calculated in a percentage. The higher the RTP the more players can expect to win over time. Each game has its RTP, with Blackjack and slots having some of the highest RTPs. Players should aim to play at casinos offering over 97% RTP on most of their games since such casinos offer them better odds of winning bigger amounts.

House Edge

Another common casino term is the house edge. A house edge is the opposite of RTP. It represents the percentage of every wager made by a player, and it shows the average gross profit a casino can expect to make from every game the players play. A game with a high RTP means the casino only gets a meager profit from it. For example, if a game has an RTP of 99.5%, the casino only gets 0.5% from it.

Reload Bonus

Casinos reward players with bonuses to attract and retain them. Apart from the first deposit bonus, casinos also reward players for subsequent deposits. A reload bonus is a bonus that comes in the form of casino credits or cash when a player deposits a specified amount of money into their casino account. Reload bonuses often follow welcome bonuses or first deposit bonuses. They are rewarded to both new and existing players.

Free Spins

Any slots lover must have heard the term free spins. It means the spins that a casino awards its slot players for free. Players don’t have to spend any money when using free spins to play their favorite slot games. In most cases, casinos reward players with free spins as part of a bonus package. Normally, such rewards come as a first-deposit package for new players. However, it can also be part of a reload bonus. When casinos offer free spins, they specify the slot games that they should be used on by players.


A jackpot is the biggest cash prize that is attached to a slot machine or other games. Jackpots are mostly tied to progressive slot games. The amounts are monumental and have been known to make lucky players instant millionaires. Some progressive slot games that have paid out huge amounts include Mega Moolah and Mega Fortune. The Mega Moolah mega jackpot amount starts at $1 million.


A payline is a common term relating to slot machines. It refers to a line that results in a win. It is a combination of symbols used in a particular slot game. This line of symbols on a slot game could be horizontal, diagonal, or vertical, and can win a cash prize.


Reels are also a part of slot games. They refer to vertical positions on the slot grid which a player spins after placing their wager. Different symbols then land on these reels to produce a winning combination.

Random Number Generator (RNG)

This is a mathematical hardware or computational device that casinos use to produce random and unpredictable numbers through a multi-stage process. The RNG ensures that all the results are random. Casinos use them to assure players that their results are not manipulated in any way since they are always random.

High Roller

A casino’s high roller is a player who spends high amounts of money wagering on their favorite games. High rollers have certain casino privileges such as exclusive promotions.
