  • How To


Slot machine gaming doesn't take a lot of expertise and is really simple to learn. They became a common element in all casinos throughout the world as a result. In light of this, slot games have their own vocabulary, just like any other casino game.

No matter if you play online or at a physical casino, knowing and comprehending these words can make your gaming sessions lot more pleasurable. The key words that every slot player has to understand are listed below.




You can unwind as the game plays on its own thanks to the auto-spin option. The way it operates is that you may instruct the machine to go through a specified number of spins automatically by setting the game to auto-spin. On some slots, this mechanism is not accessible.


Coin Size and Coins


Coins are used in slot machines to represent the amount you bet with each spin. They are your in-game cash, therefore you should be aware of how much coins are equivalent to real money.

The phrase "coin size" refers to the amount of money you are actually betting with each spin. To prevent making mistakes when betting and placing wagers that are bigger than planned, it is important to understand both coins and coin size before playing.


Free Spins


Free spins are a type of in-game bonus feature that rewards you with a certain number of spins you can use free of charge. However, they are often a part of the best online casino bonuses out there as well. You typically trigger this prize by lining up the appropriate symbols across your paylines. Free spins are an excellent way to make the most out of your money, as you get the opportunity to win without risking any of your cash.


Progressive and Jackpot


The jackpot at the slot machine you're playing is the highest advertised reward that may be won. Although significantly more lucrative, the progressive jackpot is comparable to the regular jackpot.

Every player can participate in and win the pooled reward known as the progressive jackpot for a given game. Although it may reach tens of millions of dollars, you should be aware that playing these games is frequently more expensive. If you want a chance at the big prize, you frequently have to wager the maximum number of coins on each spin.


Loose Slot


A loose slot is a gambling term used to describe a slot machine paying out more often or more money than normal. It’s sort of an urban myth, as there’s no real metric that can help you determine if a slot is loose, tight, or normal.


Maximum Bet


The betting option automatically selects the maximum betting amount you’ll place for the particular spin. It’s a mechanic you should be very careful when using, as robust slots may eat away several hundred dollars with just one maximum bet spin.




A payline is the slot’s betting line, a combination of symbols that showcase the outcome of every spin you make. Old-school slot machines only had one horizontal payline. Modern games, especially online ones, can have several dozen paylines stretching not only horizontally but in many other shapes and directions.


Pay Table


The pay table is the slot's map that includes all of the necessary information you should know when playing a specific slot. It shows you the available in-game symbols, how much each character is worth, and how the bonus features work.

It’s vital to be familiar with the slot's paytable before putting any money into the game.

Pay tables are also very important in video poker, as choosing the right game variations can have a huge impact on your bottom line.


Pick Me Bonuses


Just like free spins, “Pick Me” is a type of bonus you’ll come across in some slot games. It’s a multi-choice mini-game in which you choose between different icons or images to uncover mystery prizes behind each one.




A reel marks the vertical position on the slot’s grid, labeling symbols spun after placing a bet. Reels come with every slot game, no matter how simple or complex it is. They are one of the most critical aspects of every slot machine.

Modern slots come with a wide variety of extra features. Some of the most notable ones include rotating reels, cascading reels, and tumbling reels.




The RNG abbreviation stands for Random Number Generator. No matter if you’re playing in a land-based or online casino, make sure that the slot game you’re betting uses RNG software.

RNG is sophisticated software that impacts the outcome of each spin.

It’s specifically designed to make the outcome of each spin random and unpredictable. This means you can’t affect the outcome in any way, nor expect any particular result based on previous spins.




Short for Return to Player, this is a number that measures how much of your bet you’re getting back in the long run. It’s expressed in percentages, with each slot having a different RTP value.

From the player’s perspective, you should look for slots with RTPs in the high 90s, as they will provide you with more money over a more extended period of play.


Scatter Symbols


Scatter symbols are unique and special symbols that function differently depending on the game you’re playing. In some slots, a scatter symbol triggers a bonus mini-game, like free spins or “Pick Me” bonuses. In other slot machines, it directly acts as a multiplier to help boost your winning combination. As the name suggests, scatter symbols will activate regardless of where they land on the reels. They don't need to be a part of a particular payline to go off.


Wild Symbols


Slot machine wild symbols are quite helpful; they function similarly to how a joker does in most card games. Most slot machines allow you to set up a winning combination by substituting one wild symbol for any other symbol.

The only symbols that the wild symbol cannot replace are the aforementioned scatter and bonus symbols. However, in certain games, wilds can also serve as scatters, giving them a dual function and increasing their excitement.


Win Both Ways


You have the option to line up a winning combination going from the left to the right or vice versa on a "Win Both Ways" slot machine. Two winning possibilities are always preferable to one from a mathematical standpoint.

This glossary of slot words should make it easier for you to identify the finest games and increase your enjoyment of online gaming.

However, no amount of jargon will help you defeat the slots since the house edge always prevails. Texas Hold'em poker is a game where skill ultimately prevails over luck.
