Online Slots Glossary A-Z

Playing the best online slots opens the door to lucrative fun. If it's your first time spinning the reels, you'll quickly find that online casinos speak their own language. Browse this online slots glossary to learn about types of games, slots features, and slang terms that will take your gaming to a new level.

Types of Online Slots

No two online slots are the same, but most fall into a handful of key categories. Below are the most popular types of online slots and what sets each one apart:
  • Bonus Slots: These slots have only one payline, but if your spin includes one or more bonus symbols, you're in for a big win. Line up three bonus symbols for a major payout or extra free spins.
  • Five-Reel Slots: Slightly more advanced than three-reel slots, five reel slots such as Happy Mushroom have more paylines and allow you to play up to five coins. They also offer more chances to win, which keeps many players spinning.
  • Multi-Spin Slots: Also known as mega-spin slots, these games combine up to nine slots in one, with up to 45 reels and dozens of paylines.
  • Progressive Slots: These games are part of a larger network that shares a single jackpot. When you play progressive slots such as Mega Fortune, the jackpot grows until one lucky player wins big.
  • Three-Reel Slots: Considered classics, three-reel slots such as Bars and Bells are based on the first-ever slot machines. They have up to five paylines, and although they look simple, they tend to offer big payouts.
  • Video Slots: One of the most common online game types, video slots such as Ghostbusters have five digital reels and up to dozens of paylines. They typically have engaging themes, and some show short clips. Many game providers license characters and themes from popular movies for added fun.

Slots Features

While online live casinos offer many opportunities for fun, many players maintain a firm focus on winning. Before you start playing, make sure you know how to optimize your winnings and what each of the following terms means:
  • Autoplay: You can use this feature to automate gameplay for smaller games. Set up parameters such as the number of spins and when to start and stop spinning.
  • Bet: Most online slots allow you to alter your wager within a range of min and max bets. Some slots allow you to wager max bets of hundreds of pounds.
  • Blank: Effectively a non-symbol, a blank is an empty area between symbols. Spinning a blank typically makes your chances of getting a winning combination impossible.
  • Bonus: A bonus helps players increase their winnings in the form of features, rounds, and games.
  • Cash Back: Some casinos and slots offer cash back as a reward for depositing a certain amount of money.
  • Coins: These betting units change in size depending on how much you want to wager.
  • Credits: You can buy credits to play and convert them into cash after a win.
  • Free Spin: Many online slots offer extra spins and extra opportunities to win when you collect certain symbols or trigger other features.
  • Jackpot: You'll win the largest payout on games such as Millionaire Genie when you hit the jackpot. The amount you wager generally affects the size of the jackpot.
  • Payline: This is a line that passes through each reel to connect symbols. When certain symbols appear on a payline, you win. Online slots can have anywhere from one to 243 paylines, for an impressive amount of variety.
  • Pay Table: Every slot has a pay table, which details the winning combinations for that specific game. For example, the Kingdom of Cash pay table explains how wilds, scatters, and free spins affect your potential winnings.
  • Multiplier: These symbols increase your winnings by two or more times.
  • Primary Jackpot: This jackpot is the biggest payout prize and the largest jackpot.
  • Random Number Generator: Also known as an RNG, a random number generator is a programming feature that generates random spins, keeping online casinos neutral and fair.
  • Scatter: These symbols typically trigger bonus games or free spins.
  • Wild: These symbols substitute for other symbols, and in some games, they stack or expand.
