Glossary of Terms for Online Video Slots

As Any Other Casino Game, Video Slots Have Their Own Language Too That Everybody Playing Slots Needs To Understand


These terms can be very useful, particularly if you are a rookie in the online video slots world. By having a better grip on the terminology, you can help yourself to understand the game much better. Feel free to re-visit this glossary page until you feel you have learned the terms well.

Bankroll – A ‘bankroll’ is the total amount of money that you have in your online casino account that you intend to use for playing the casino games among which slots. If you are playing in a land-based casino, then your bankroll is the total amount of coins that you have for wagering on a slot machine.

Bonus Feature – Bonus features are commonly found in video slots, while classic slots don’t have bonus features. A ‘bonus feature’ is sort of a special mode with which a mini bonus game is activated. Bonus features can earn you free spins, usually accompanied with multipliers with which your potential winnings are multiplied.

Coin Size – Before you start spinning the slot reels you have to set the size of your bet. For example, if you choose each of your bets to be $0.20, and you set the coin size to 5, then every bet you make will be $1. The bigger the coin size, the bigger your winnings will be. The coin size can help you adjust the bets to the limits of your bankroll.

Coins per Line – This is when you set how many coins you are going to bet per payline. If there are 25 paylines, and you set your bet to 1 coin per line using a coin size of 0.1, then your total bet will be $0.25. Read about ‘paylines’ in our Online Video Slots FAQ page or refer to the glossary term ‘Payline’ further below.

Loose Slot – Loose slots are sort of casino myths. It was and still is believed that if a slot machine pays out more than the others then that slot is a loose slot, or sort of broken. It was also believed that loose slots can be found at the end of the line of slot machines in land-based casinos.

Max Bet – The maximum bet is when you set the coin size to the largest value. Playing the maximum bet is not always recommended, but when playing progressive jackpot slot, then you have to play the maximum bet in order to compete for the progressive jackpot.

One Armed Bandit – This was the name given to the first ever slot machines that first appeared in the 19th century. They were called ‘One Armed Bandits’ because of the lever that was used to spin the reels and because when people lost their money without winning they felt like being robbed, hence the name bandit.

Pokies –This is the Australian name that is used to refer to ‘slots’.

Progressive Jackpot – A progressive jackpot is a jackpot that turns ordinary slot players into millionaires. This is because progressive jackpots tend to go into millions, although there are those that don’t reach the million dollar mark. The progressive jackpot of a slot game is formed by taking a fraction of each bet made into the game or into other slot games that contribute to the same progressive jackpot. In order to win it you have to play the maximum bet and you need to land a specific combination of symbols, which is described in the paytable of each progressive slot.

Payline – Winning combinations are created by certain symbols aligning into a specific line, which is called a ‘payline’. This payline doesn’t have to be a straight horizontal line, but instead can go zig-zag.

Payout – When a winning combination in a slot game has been created for which you are given money, it is called a ‘payout’.

Payout Percentage – In statistical terms the payout percentage is a percentage that you are expected to receive on a long term out of each bet made. The higher the payout percentage of a slot game, the more frequent the payouts are. Best thing is to find a slot game with a high payout percentage, usually with a percentage not lower than 96%.

Paytable – Every slot game has a paytable which can be accessed by clicking on the ‘Paytable’ button. There you will find information about the paylines, the winning combinations, bonus rounds, jackpots, rules and so on. It is always advised to first see the paytable and study it before playing a slot game in order to see if the game is any good compared to other slot.

Random Number Generator (RNG) – This is a technology on which every slot game is based today. It doesn’t matter if it is a land-based slot machine or online slot, every slot game has one. Moreover, all types of online casino games work with the RNG. The RNG is a computer program which decides on the outcomes of the game in a random order. This program is in perpetual motion and creates infinite number of combinations; you just need to have the luck to press the ‘Spin’ button at the right time.

Reel – The reels are those vertical columns with symbols on them. In the past when slots where mechanical machines and not computerized games, they had spinning reels in them with symbols painted on them. When these reels stopped spinning and if the symbols formed a payline, a payout was triggered. It is very much the same with today’s slots, only that the reels are simulated on a screen.

Scatter – Scatter is a very important symbol in video slots. It can replace a missing symbol from a winning combination in order to complete the payline and can appear anywhere on the reels. If you land 3 or more scatter symbols on the reels in most of the video slots, usually a special bonus feature is activated.

Symbols – The symbols are the pictures on the reels that form winning combinations. Typically, the symbols are designed according to the theme of the slot. In classic slots the symbols are usually numbers, letters, or fruits, because of which they are sometimes called ‘Fruit Machines’.

Wild – The wild is another symbol typically found in video slots. It can replace other symbols in winning combinations and usually activates multiplier bonuses. Some video slots have ‘stacked’ or ‘expanding’ wilds, which means that one or more wild symbols can be stacked on top of one another or that they can expand throughout the reels.
