While the basic mechanics of a slot remain the same across games and features, different types of slots are available, each with unique features.
Retro Slots
Retro slots are online slot machines adapted from older land-based counterparts. These enjoy significant popularity with players, as the classic slots have a built-in fan base. You can find titles like the Fruits and Clovers slot at the local betting shops and online platforms.
3/5 Reel Slots
You’ll find that most slots are 3×5 grid games, like the Book of Dead slot. These slots are the more traditional types, and you can often win big on basic spins. A 3/5 reel slot will feature wild symbols that can substitute for other symbols and more bonus features.
Progressive Jackpots
Progressive jackpots connect to a network and keep growing as you play, like the Mega Moolah slot. The jackpot can keep growing indefinitely until it’s won, awarding the biggest wins of all slot types. However, regular wins tend to be smaller.
Cascade Slots
These slots offer cascade wins, which explode the symbols on a winning payline. New symbols fall to replace the winning symbols, possibly triggering another win. You have more frequent chances of winning, but generally in smaller amounts. These remain entertaining, especially when bonuses are triggered, like in Sweet Bonanza.
Megaways
Megaways offers hundreds to thousands of ways to win, featuring two to seven rows. The number of paylines can change with each spin, and these have become one of the most popular types of games. Big Time Gaming introduced this mechanic, and popular titles like The Dog House Megaways are now available.​
Multipliers
Multipliers are often found in various slots, but multiplier slots take it to the next level. These combine the bonus buy feature with multipliers, giving your bonus feature an overall multiplier attached to your winnings. Titles like Thunderstruck Stormchaser use these to award bigger possible wins in the free spins round.
Everything You Need to Know About Online Slots Before You Start Playing
While slots offer straightforward gameplay, there are a few terms that will be good to know. These go hand-in-hand with online slots, describing standard features you’ll find when you play.
Paylines
Paylines refer to the winning combinations where symbols can fall. Most slots have between five and 50 paylines. They can be fixed in place, or you can adjust how many you want active while playing. The paylines will be outlined in the pay table.
Bonus Rounds
Bonus rounds are generally triggered when you land three or more scatter bonus symbols across the reels. The bonus rounds use a specific feature or game mechanic, from free spins to unlocking chests or boxes. There are many different types of bonus rounds and ways to trigger them.
RTP
RTP stands for return to player, the theoretical payout percentage calculated on a slot. This percentage is calculated over billions of spins and refers to the lifetime payout of the slot. As such, higher RTPs are better, but it doesn’t guarantee you’ll receive that percentage in returns when playing.
Free Spins
One of the most common online slots bonus features are free spins. Generally triggered by landing scatters, these award you between five and 20 free spins most times, with more free spins occasionally available.
Volatility
Volatility refers to the frequency of wins and the size of those wins. Games with equal RTPs can still trigger wins at different frequencies due to the volatility.
Low
Low volatility means you will tend to trigger more wins, but they will usually be in lower amounts. However, this doesn’t mean that bigger wins aren’t possible, like in the Starburst slot.
Med
Medium volatility fills that sweet spot between low and high volatility, offering a more balanced gameplay. When you spin the reels, medium volatility has a good balance of frequent wins and more significant winning amounts. Examples of online slots with medium volatility are NetEnt’s Steam Tower and Halloween Fortune by Playtech.
High
High volatility means you might trigger wins less frequently, but you’re likely to win more significant amounts when they come. Unlike the frequent low wins of low-volatility slots, you will land higher wins more spread apart. Examples of high-volatility slots are progressive jackpots and Pragmatic Play’s Big Bass Bonanza.
