Just recently, the UK Gambling Commission has published a new report urging operators to take greater care in helping new players understand how gambling works: from familiarizing them with specific slot machine terminology to acting more decisively when dealing with at-risk players.

Understanding slot gambling lingo is important, as it helps you to understand how the games work, what to expect, and ultimately, how to have more fun. Today, we take a closer look at the specific slot terms you may have already come across but never knew the meaning of.

Understanding the core terms of a slot machine

To help you understand slot machine lingo, there are two main categories that you need to focus on: the technical terms that explain how slots work and the gameplay terms. We will start you off with the technical terms first. Here is what you should know.

  • RTP: The theoretical return to player is a popular metric that simply denotes how much you can expect to get back for every $1 wagered. If a slot has a theoretical return of 98%, this means that you can expect $0.98 for every $1 you place. However, this is an average metric over thousands of plays, meaning that the short-term results could potentially be higher or lower. Playing high RTP slots is usually what most players go for.
  • RNG: The Random Number Generator is the specific software that is used to create the "randomness" in online slot games, but also for land-based machines. Computers cannot create "true" randomness, so they use a specific algorithm, the RNG, to create random-like events.
  • Volatility: When it comes to slot machine lingo, volatility is a very useful term to know. In simple terms, it has to do with how much and how frequently a game would pay. A high-volatility slot pays less often but pays more. Conversely, a low-volatility game pays more often, but pays less per payout.
  • Paylines: Paylines are specific combinations that pay when symbols appear there. However, paylines are not necessarily mandatory. Features such as all-ways pays and cluster pays are also available, and they often just require the symbols to be present anywhere on the reel, rather than appearing in a specific combination.
  • Paytable: The paytable is another essential piece of slot machine terms. Essentially, these are the rules for how the slot game pays. There are often fixed paylines and specific combinations, and, more importantly, each symbol has its allocated value in the paytable. It is a handy guide to how much each symbol pays.

Slot machine lingo: Symbols and features

Next up, it’s important to understand the actual gameplay elements of a slot machine, as well as understand what these terms mean.

TermDefinition
ScattersScatters are a special symbol that is usually tied to free spins or bonus rounds. The scatters usually trigger the features, whether they require three, four, or five of a kind to do so. Normally, scatters only trigger the free spins, unless there is a dedicated bonus symbol. Otherwise, they may also trigger the bonus round. This is not an absolute rule, however, and you can see differences in the role scatters serve from one game to the next.
WildsWilds are a type of symbol that substitutes for certain regular symbols. They serve to replace the value of almost any symbol and fill in for a missing one. They cannot usually replace a scatter or a bonus symbol, however.
MultipliersMultipliers are special built-in features that will simply do what their name suggests - multiply your win, whether by x2, x5, x10, or even x1000. The maximum multiplier will vary from game to game, and some games will simply have multipliers populate the reels very frequently.
Bonus roundsBonus rounds are fully dedicated features that are usually played on a second screen, away from the main game. Early super popular bonus games include Jack and the Beanstalk as well as Jumanji by NetEnt, both of which have developed amazing second-screen games.
Free spinsJust like bonus rounds, free spins usually mean you get free rounds, that is, spins of the reels. Free spins usually only focus on this, i.e., granting you 5, 10, 15, or more free spins off the same bet you placed. They are an incredibly popular feature, and there is hardly a slot machine these days that can do without it and expect to be successful.

Slot machine lingo you will hear people say

Depending on where you are in the world, you will hear all sorts of terms used to describe slot machines. Here are a couple of popular terms to keep in mind.

  • Pokies: Pokies is the term used to describe slot machines that is commonly used in Australia and New Zealand. While they are technically called poker machines, many people refer to them as pokies colloquially. The etymology might have to do with the fact that early slot machines would need you to match several-of-a-kind to win - like a poker combination.
  • Fruit machines: Fruit machines is a British term used to describe slot machines. The etymology may have to do with the fact that early slot machines used fruits as their preferred display symbols.
  • One-armed bandit: This is a popular term that describes a classic slot machine, before the modern day of slots, when a person would have to pull a physical lever in order to spin the reels. The bandit in the name comes from the fact that you may win, but you may very well lose, or be "robbed" by the "bandit."
  • Penny slots: Penny slots are a popular slot term used to describe games that require a small amount of money to place a minimum wager. They are popular with budget players and can still lead to some alright wins.
  • Hot and cold slots: Part of the gambler’s fallacy, hot and cold slots are machines that are supposed to either be less likely to pay at a certain time or more likely to pay. This is, of course, not correct, as even though a slot can go without a win for a while, this doesn’t automatically increase the chance of people winning if they play the slot because it’s suddenly "hot."

Slot lingo FAQs

If I know slot terminology will I win more money?

Not necessarily. Knowing slot terminology will help guide you to potentially better games for your budget - high volatility vs. low volatility, low-RTP vs. high-RTP. However, the odds of winning at a slot machine are always fixed and the RTP is a fixed value.

Is it important for players to understand slot terms?

Yes, by understanding metrics such as volatility, RTP, and core mechanics, players can make informed decisions about what games they wish to play.

If I bet higher amounts on slots, will I win more?

No, not necessarily. Wins are based on random events. While theoretically placing and winning with a better stake would lead to a higher payout, this is not guaranteed, as you may as well lose your stake.

What is hit frequency?

Hit frequency tells you how much of the time you can expect a slot to produce a winning outcome. Thus, a slot with 40% hit frequency would produce winning outcomes 4 out of 10 times over the long run.

Mind your language and stick to the facts

Understanding slot lingo will allow you to understand the games themselves. Slots are based on random outcomes, and as such, you may not influence them. Then again, by understanding technical terms such as volatility and RTP, you can choose the best online slots for yourself. Remember to enjoy the game, and stick to the facts.
