Slot Machine Symbols Explained: Wilds, Scatters, and Bonus Icons

If you’ve ever thought that the symbols on online slots are just pictures drawn at random, then you’re missing out on one of the biggest factors that affect your outcome in play sessions on the best online casinos.

Understand these symbols and how they work, and you’ll have a leg up on slot jockeys who are just mindlessly pressing buttons.

In this guide, we’ll tell you everything you need to know about how standard slot symbols work on the top online casino apps, as well as break down key info on wilds, scatters, and more.

🎰 Why symbols are more than decoration

Unlike table games like online blackjack, where you need to do a little math to get ahead, the symbols on a slot machine are what determine everything from whether you win to how bonus rounds are triggered. A symbol’s frequency determines its value. Some pop up all the time and trigger small wins. Others are quite rare, and these trigger big payouts or lucrative bonus rounds. 

Once you understand the different symbols and what they represent, you’ll be better able to strategize each spin (and know when it’s time to get excited).

👑 Standard symbols

Most online slots and games on the casino floor have two different classes of symbols: low-value and high-value.

Many slot games use card symbols, like Jacks, Queens, Kings, and Aces, to represent low-value symbols. These were borrowed from poker because they’re universally recognized, creating a minimal learning curve. Depending on how many you land on the reels, these symbols typically payout anywhere from 0.5x-20x your bet, giving you frequent, small wins that keep the game moving.

Higher-value symbols are usually unique to the game in question. For example, on an Egyptian-themed slot, these might be things like ankhs, pyramids, or pharaohs. For a pirate-themed game, you may find pirate ships, treasure maps, treasure chests, or golden doubloons. Besides offering bigger payouts (ranging from 5X to 500X+), these symbols establish the game's theme and overall identity.

🔔 Wild symbols

Wilds substitute for other symbols to give you winning combos. There are different types of wilds, however. Some of the most common you will find at real money online casinos include:

• Standard wilds – These are simple substitutions that fill in for other symbols as needed to give you a win.
• Stacked or expanding wilds – Stacked wilds line up vertically on a reel, and expanding wilds can stretch to cover that entire reel, dramatically increasing your win potential.
• Sticky wilds – Rather than expiring after a win, sticky wilds stay in place for multiple spins to give you even more chances to win. They’re frequently used in bonus rounds or free spin features.

It’s important to understand how a slot’s wild symbols function, as they’re the key to big paydays and extra features like bonus rounds.

💎 Scatter symbols

Besides wilds, many slots also feature something called scatter symbols. Rather than triggering a win, scatters usually trigger free spins, bonus rounds, or multipliers.

Scatters usually pay regardless of where they land, and you’ll need at least three to trigger their function. However, scatter wins are typically added on top of slot payline wins, so they provide pure extra value. Most of the time, the absolute best features require scatters to be triggered, so it’s worth figuring out what they are and how many you need before you start playing.

🚀 Bonus & feature symbols

The final category is bonus and feature symbols. These often unlock bonus games or mini-games, adding to a slot’s excitement and variety. Some of the most common types of these symbols include:

• Pick & Click symbols – These trigger interactive bonus games that reveal cash prizes, add multipliers, or grant access to a progressive jackpot spin.
• Progressive jackpot symbols – These give you a chance to hit the biggest prize possible (on some slots, such as Mega Moolah, this could mean payouts in the 8-figure range).
• Multiplier icons – These symbols multiply your base game or bonus payouts. For example, if you hit a 2x multiplier, your winnings will be doubled for a certain amount of time.

🍒 How symbols affect your gameplay strategy

Symbols have a dramatic impact on how fun (and potentially lucrative) a slot can be. Many players pick games based on their symbols alone. The best way to guarantee you have fun is by learning which types of symbols and features you really value in a slot, then looking for the best sweepstakes casinos that offer those games.

📝 Quick tips for paying attention to symbols

If you’re new to the world of slot symbols and how slot machines work, there are a few things you should do before each session. These include:

• Checking the paytable to see what symbols are offered and their payouts.
• Making a note of which symbols are the most lucrative, as well as where wilds are likely to show up.
• Figuring out what’s needed to trigger bonus rounds and how often they occur.
• Playing the game for free in demo mode to learn its mechanics and how the symbols operate.

Doing this will go a long way towards setting you up for success. Of course, you don’t have to – all that matters in the end is that you have a good time and gamble responsibly. Good luck!
