Slot Features

Slot features

These are essential components in a slot game. Slot features are for making gameplay exciting while boosting your chances of winning. Any beginner video slot player may find the various feature in a slot intimidating. However, they are easy to understand after playing the game, especially the demo version. You begin to recognise the various slot features as you play more slots.

Common slot features. There are some features synonymous with any free slot game. Let’s highlight some of these features below.


The paytable is the first thing to check before playing any free slots games online. This displays the game’s main symbols and bonus features. Looking at the paytable allows knowing the payout of each symbol, including the process of activating the bonus round and what the symbol does.

You’ll be in an excellent position to understand what’s likely to come after initiating a spin. The paytable also has details regarding the paylines and mechanics for building the slot. It may also include betting strategies and key stats, including the hit rate, max win, volatility, and RTP.

Random Number Generator

Many people usually wonder whether it is possible to rig online slot machines. However, this is impossible since the outcome from every spin depends on the Random Number Generator (RNG).

This explains why people call slots a game of luck. A slot machine generates thousands of random numbers every second. The most recent random number will determine whether the game is a win or loss whenever you click the spin button.

Return To Player

The RTP rate is the average percentage of bets the slot will pay if a player wins. In a game with 96% RTP, theoretically, each £1 is likely to return £0.96. The casino takes the remaining £0.04.

Every slot developer sets an RTP. There’s also a chance to release different game versions with varying RTP. Online casinos decide which slot to host in the lobby. So, ensure to check this information before choosing where to play free slots online.


A slot’s volatility may be high, low, or medium. Slots with low volatility usually have regular wins with relatively small payouts. Medium volatility slots have the hit rate and payouts at a medium level. Additionally, high volatility slots are tough to come by but have the potential for huge wins. Seasoned players prefer slots with high volatility for a chance to enjoy the potential for massive payouts.


These simple logos appear as heroes depending on the slot theme and the software developer’s intention. Wilds work as substitutions for regular symbols and help create winning combinations. In basic slots, wilds substitute all paying symbols apart from the scatters and jackpot symbols.

Some complex slots rich in bonuses have one-of-a-kind variations that appear in the bonus rounds. These may have various wilds such as sticky, spreading, and regular wilds.


These are your best friends while playing any slot. Only a few games might miss having scatters. However, these usually have something like bonus symbols performing a similar function to scatters. The most significant use of scatters is triggering bonus games, including mini-games, free spins and other bonus rounds.

The game rules detail the number of scatters you need to trigger the bonus feature. Most slots require three or more. The more scatters, the bigger the bonus, including free spins. However, scatters don’t usually follow payline regulations. You may pin them and get a reward regardless of position without having to line them on the reels. The action of the scatters depends on the game developer’s imagination.
