Almost all slot games have the same base instructions - simply click the spin button and the game does the rest! Slot games do not require any skill or strategy. As wins are down to chance, they appeal to all levels of player. 

The basic rules of winning are to line three or more matching symbols along a pay line. Based on the paytable and the value of the symbols, then a win is awarded to you. Online slots games can come with features to increase the thrill and the prizes or even some incredible graphic animations for fully immersive gameplay! 



A slot game comes with various components that come together to form the machine we all know and love. Each of these elements plays a specific role in the gameplay, which ultimately, is meant for your entertainment or to bring you some prizes. The following covers the most common ones to expect in an online slot game.  



To win, you need to match identical symbols in a specific order on the reels. This is called a pay line or a win line. Each game will have a different number of pay lines. You can see what these are on each in-game help menu. Paylines are often: 

  • In a row
  • In a zig-zag pattern
  • In a V shape
  • Diagonally


The winning symbols for each game vary, and pay lines are weighted differently on each spin. When you are playing with real money, your balance will be debited every time you spin the reels. You will also need to decide how much to stake on each pay line to make up your total stake. 

Some slots do not use pay lines and instead payout based on the number of symbols you land on the reels. Common examples are the Cascading Reels game engine and the Cluster Pays game engine.   

Grosvenor Pro Tip: Megaways Slots offer the highest number of ways to win, with some reaching up to 117,649 ways! That’s 117,649 chances of winning!! 



As well as being ultra-simple, people like to play online slots for their special features and bonus rounds. Free spins, Prize pickers, Jackpot rounds and many more are some additional way to win, adding excitement and variety to our games. Here are some common features to expect! 


Wilds, Scatter &, Bonus Symbols

A Wild symbol can fill in for any other symbol on the reels by chipping in for the missing symbol in a combo. They typically don’t substitute for Free Spins, Scatters or other bonus symbols. Scatters and Bonus symbols are mostly in place to unlock in-game bonuses, but this differs with each online slot.  

Re-Spins Features

A feature made popular through NetEnt’s Starburst Slot. The bonus is activated at random or when you land a special symbol. The reels undergo a re-spin for free, in an attempt to give you another win that can improve the payouts! Re-spins can be accompanied by Sticky Symbols or Sticky Wilds, which are locked on the reels for the re-spin to further improve the wins. 


Free Spins Features

The most common way to trigger free spins features is by getting several scatters. Free spins are granted based on the number of scatters used to trigger the bonus. This bonus does not count on your stakes, which means you will reap prizes for free! Some extra rewards and bonuses can be included in the Free Spins Rounds of certain slots online. 


Prize Picker Rounds

Simple as they sound! This bonus round is usually triggered through bonus symbols and the general rule is to select symbols on the screen to claim a prize. Slots can go the extra mile to offer access to additional features through the Prize Picker round… even Jackpots! 


Jackpot Rounds

Not all online slots games trigger a jackpot straight away! To spice things up, a jackpot round is included which comes in the form of a Wheel of Fortune or a prize picker round. The aim?
