Most common slot machine terms

Most common slot machine terms

These are the must-know slot machine terms, from slots synonyms to casino games mechanics. And we also took care to help you steer clear of any terminological confusion.

Synonyms for slots

  • Coin machine

Self-explanatory, it’s a machine running on the coins you insert into it.

  • EGM

An abbreviation of Electronic Game Machine. Do not confuse it with EDM, which stands for Electronic Dance Music!

  • Fruit machine

This slot machine term comes from the fact that traditionally, symbols appearing on your screen are fruit themed.

However, many slot games developers decide to take a new spin on the symbols, providing Egyptian-themed products or taking inspiration from high-rated pop-culture creations.

  • One-armed bandit

A metaphorical way to look at slots – since most EGMs have one handle you use to keep spinning, it’s as if you were shaking the arm of a bandit that stole cash out of your pocket.

Gamble responsibly!

Do not spend more than you can afford on one-armed bandits! If you are worried that this situation may apply to you, please check out the tell-tale signs of gambling addiction. Experts describe the principal symptoms, but you should also further your research by consulting gambling authorities.

Slot machine terms concerning gameplay

0 – C

  • 1024 ways

A machine that has 1024 winning possibilities. Remember that in such cases, the game’s variance may be higher than for its counterparts with fewer ways to score a jackpot.

  • 243 ways

While the product has no traditional pay lines, it provides 243 ways to win. Similar to 1024 ways, it makes up for it with higher volatility.

However, it’s possible to bet lower stakes on such products than on their more traditional versions.

  • 3-reel

The classic slot variant, where each screen contains three reels of symbols. Their features are generally on the simple side, and you’ll see few pay lines throughout your gameplay.

  • 5-reel

The developers added two extra reels to the traditional 3-reel, thus increasing your chances of greater funds and making the game more volatile.

Of course, this also means that positive outcomes may be scarcer than for traditional slots.

  • 6-reel

What about a sixth reel enhancing your gameplay? This rare category was first launched in 2014 by WMS, and it makes the six-symbol combo possible.

  • Autoplay

This option lets the game do the spinning for you, both in online and offline casinos. It also counts as a responsible gaming measure since you must select the maximum number of spins, as well as the max wagering and acceptable loss.

  • Candle

The light you see on fruit machines, which goes up as you hit a combo or otherwise score a positive outcome during gameplay.

  • Cascading reel

When you score a winning combination, the screen will change, allowing you to double up on the gains you got. Also known as falling or collapsing reels.

  • Coin out

When a two or three-symbol combination brings about double or triple wins.

E – M

  • Expanding wilds

While a wild symbol is something that can take the form of any other image, helping you score combos, an expanding wild is a feature that may trigger occasionally.

It covers your entire screen in wilds, helping you secure a winning outcome for that stage in your gameplay.

  • Games per hour

The maximum number of rounds you can play in an hour of gambling. Generally, a slot machine will allow up to 500 games in this timeframe.

  • Hit and run

A player who bets on max credits on a single payline. Should the slot not pay out, the bettor will move on to the next one.

  • Hit frequency

The frequency with which you may get a combo or jackpot. Generally, games with high hit frequencies will dish out more low-value jackpots.

  • House edge

The amount that the house wins each time you spin. It’s like RTP but seen from a different perspective.

Tips

A Blackjack game with 99% RTP is also a game with a 1% house edge.

Like the return-to-player rate, this value is calculated over longer periods. Generally, it takes tens of thousands of spins on the same product until you can actually see the practical edge align with the theoretical one, accessible on each game’s paytable.

Recommendation

To better understand how the house edge works, please consult our guide on casino RTP.

  • Instant winner

Somebody who claims the jackpot on the spot.

  • Jackpot

The highest prize you may receive during a session.

  • Max bet

The most you can stake on an individual spin. Generally, slots have lower max bets than card games, although some exceptions may be.

Licencing conditions

Online casinos that operate under licencing from reputable authorities might restrict your max bets to low values. This is a method to prevent irresponsible gambling.

  • Max payout

The most you can withdraw after going through gameplay.

  • Megaways

This gameplay ensures that all lines can be pay lines.

For example

A rough calculation shows around 117649 methods to get the desired outcome.

Generally, these products have lower RTPs and higher volatilities than other fruit machines.

  • Min bet

The least you must stake during a round. Otherwise, it will be impossible to progress through the game.

  • Multiplier

An in-game bonus feature that multiplies your payouts.

P – R

  • Pay line

A line that will grant you positive results if you score a combo on it. Classic slots have three pay lines, while newer products and Megaways can have many more.

  • Payout

The funds you accrue after wagering on slot machines.

  • Paytable

It is a rules card. It tells you how many pay lines and reels the game contains, as well as the symbols you should look for.

Checking the paytable is mandatory if you want to be in the know while playing. Information relating to RTP and max payouts will generally be accessible here, too.

  • Respins

Special in-game features that let you spin once more, generally after a losing combination, free of charge.

  • RNG

An abbreviation of Random Number Generator. Fair slots employ this algorithm that ensures that all combinations are randomly generated so that nobody can rig a game’s resolution.

Do all games have RNGs?

Only trustworthy gambling sites feature providers that exclusively create RNG-based games. To identify the safest products and understand more about RNGs, our guide can help you.

  • RTP

Short for return-to-player rate. This theoretical value shows how much of your money you may expect to get back from your wagers after gambling.

Remember that the actual RTP is at first lower than the theoretical one. Still, it evens out after spinning for long times.

S – W

  • Scatter symbols

These symbols can help you create a combination even if they do not form a line.

  • Spin

It’s what you do each time you place a bet – by spinning, the symbols on your screen will change, and the wager you intended will be deducted from the balance you use for playing.

  • Variance

Also known as volatility, this parameter measures how likely losses are. Generally, high-variance slot machines will provide fewer jackpots.

However, their value will be higher. On the other hand, low-variance ones dish out consistent wins, but they are not spectacularly high.

  • Volatility

A perfect synonym for variance. This word finds itself among the most common slot machine terms, more so than its equivalent.

  • Wild

A wild symbol may take the shape of any other character on the screen, helping you create quicker combos. Checking a machine’s paytable will let you see whether the game features wilds.

  • Win

Coming out of the game session with more funds than you initially had. On a broader scale, any positive outcome you could get while gambling.

  • Win both ways

While traditional pay lines only work from left to right or right to left, the win both ways feature ensures that both sides may provide a good resolution.
