Slot Machine Symbols Guide 2025
The basic principles of how slots work are the same. At the heart of each of them is a random number generator that determines the results. You, as a player, simply select your bet size and start the spin. The reels start moving, and when they stop, the result is summed up. But despite the same principle of operation, all slot machines are very different from each other, both visually and in mechanics. Manufacturers add various bonus symbols to their games, which change the gameplay, make it more exciting and increase the number of ways to win.

What Are Slot Symbols?
There are two types of symbols in online slots. The first ones are ordinary. They are necessary to form paid lines. That is, they have one function – to give the player winnings if the conditions for their accrual are met. The condition may be to collect identical symbols on one of the lines, to obtain a cluster or a certain number of such symbols on the field.
Slot bonus symbols don’t always take part in a paid combination. They may not be taken into account at all when forming lines. They have a different task – to make the gameplay more diverse. Bonus symbols can give an additional multiplier, activate free spins, re-spins, open new reels, play a jackpot, etc.

Slot Symbols History
The first slot machine in history was developed by American engineer Charles Fey at the end of the 19th century. It was a simple mechanical slot called Liberty Bell. It had only one row and three reels. To get a win, the same symbols had to appear on two or three reels, starting from the first.
Like dozens of others in the future, this slot machine used symbols of card suits, diamonds and horseshoes. The image of a bell was considered the most valuable. These symbols have become classics, and for many years, until the mid-20th century, they could be found on most slot machines.
Later, symbols of fruits and berries were added to them. However, both these and the symbols described above were not bonus symbols. The only function they performed was the formation of paid lines.
Real bonuses slot machine symbols began to actively appear in the second half of the 20th century when gambling in Las Vegas and other resort cities experienced its heyday. The emergence of online slots casinos gave them the greatest development.

Types of Slot Machine Symbols
There are many types of slot game symbols, and each of them performs its special function. Slots can have either one of these symbols or a whole set. The main types of bonus symbols, how they work, as well as the slot games list where you can find them, are shown in the table below.
Bonus Symbol | Definition | Slots Examples |
---|---|---|
Wild | Replaces any other symbol when forming a winning combination | Legacy of Dead Starburst The Wildos |
Multiplier | Increases the size of the current winnings by a certain number of times | Gates of Olympus Sweet Bonanza Midas Goldentouch |
Scatter | Triggers a series of free spins | Book of Dead Zombie Carnival In Jazz |
Bonus | Launches the bonus game | Hottest 666 Floating Dragon Megaways Divine Fortune |
Standard | A common symbol for forming paid combinations | Mongol Treasures Book of Santa Pink Elephants 2 |
Stacked | Identical symbols that can be located on top of each other | Money Train 2 Honey Rush Retro Tapes |
Sticky | Symbols that are fixed on the reel for the next spins | The Dog House Cleopatra Wild West Gold |
It happens that one symbol combines several functions at once. For example, in slots whose names begin with Book of, in most cases, the scatter also acts as a wild. And in many other slot machines, wilds have multipliers.
Wild Symbols
This is the most common type. Slot machine symbol values are that they can replace any other symbol when forming a paid combination. Wild replaces all symbols except other bonus symbols.
In addition to the regular wild, there are bonus symbols with additional options:
- Sticky. Remains on the reel during the next spin;
- With a multiplier. Adds a multiplier to any winnings in which it participates;
- Expanding. Can occupy not one, but several cells on one or adjacent reels;
- Moving. With each rotation, it changes its position on the playing field.
Some slots have several types of wilds at once. You can see what a particular slot machine has in its rules.

Multiplier Symbols
When this symbol is included in a paid combination, it increases the winning amount by a certain number of times. The multiplier can be triggered if it is part of a combination, or without this condition.
Such bonus symbols can be divided into two types:
- Single. Triggers once for one combination;
- Cumulative. They gradually accumulate. This usually happens in the bonus game and free spins.
If several multipliers are triggered at once, their values can be added to each other or multiplied.

Scatter Symbols
Scatters do not take part in the formation of a paid line. The only function of this bonus symbol is to trigger free spins, a bonus game or other special mechanics. As a rule, at least three or four scatters must appear on the playing field during one spin to proceed to the free spins round.

Bonus Symbols
Slot machine symbols’ meanings are almost the same as the scatter. But they do not activate free spins, but a bonus game. For example, Hold and Win or Wheel of Fortune. More than three bonus symbols may be required to trigger a special feature.

Standard Reel Symbols
Regular symbols are only needed to form paid combinations. Winnings can be awarded by lines, per cluster, or by the number of identical symbols on the field. Each symbol has its payout ratio. They are divided into high-paying, medium-value and low-paying.

Stacked Symbols
Such symbols can be located above each other on the same or adjacent reels. Thus, one character can occupy several cells at once. For example 2×2, 3×3, 4×4 and even 5×5. This increases the chances of winning and its potential size.

Sticky Symbols
The main feature of these bonus symbols is that they remain in place for one or more subsequent spins. For example, in some slots, if a payline begins to form, then all the identical symbols along it remain for the next spin. If the line is extended as a result, another respin occurs.
Sticky bonus symbols are especially common in free spins. For example, the wilds may remain in place until the bonus game is completed.

How Many Symbols Are There in a Slot Machine?
Each slot has its playing field format, that is, the number of reels and rows. This means that the total number of characters in its field may vary significantly. For example, in classic slots with 3 reels and 5 rows, 15 symbols appear on the screen in one spin. If there are 5 reels, then there are already 25. And in slots with a playing field format of 10×10, there are already 100 symbols.
But it is worth considering that we are talking about the total number of cells. If we talk about unique symbols, there are usually no more than 15 of them. Moreover, not all of them are bonus symbols. As a rule, new slot games use up to 3-5 bonus symbols in different game modes, so as not to complicate the gameplay too much.

Slots Symbols Conclusion
Bonus symbols are what make slot machines unique. They add more variety to the gameplay and provide additional ways to win. There are more than 10 types of bonus symbols, and each performs its functions. Slot machine providers use them in combination with each other, which further increases the winning potential. Often, bonus symbols can perform several functions simultaneously.
But slot machines with bonus features have more complex rules of the game. Therefore, before making money bets, it is advisable to study them and understand how certain mechanics work. This will help you evaluate the slot more objectively and make a final decision on playing it.
