Online Slot Features
- RTP – The Return to Player percentage (or RTP) is a hypothetical rate at which online slots could pay out wins over its lifetime of spins. The higher the RTP, the lower the house edge and the more chance you stand to win.
- Volatility – Also known as the variance, this aspect of online slots can help you determine which slots will suit your budget best. High volatility slots pay out large sums less regularly while low volatility slots pay out small amounts more often.
- Paylines/Ways to Win – Paylines or ways to win will vary from slot to slot. These paylines are the number of lines available for you to bet on. They can range from 10 to 7000 ways to bet on a single slot.
- Free Spins – One of the most popular bonus features found on online slots, free spins give you the chance to play without spending any cash. Triggered by landing certain symbols on the reels, free spins can often be retriggered for more ways to play for free.
- Multipliers – This feature is a great way to boost your bankroll with ease. Multipliers allow you to double, triple, or even quadruple your win by triggering this feature. Many slots offer multipliers and can even go as high as 50x your bet or more!
- Wilds – One of the most popular features found on most online slots, Wilds come in many different shapes and forms. Expanding Wilds, Stacked Wilds, Sticky Wilds, and Shifting Wilds are all forms of this feature available. Check out the game’s info section for more information about the Wild feature, how it can be triggered, and how it will work.
- Scatters – These bonus symbols are often used to trigger special games such as free spins when playing an online slot. Scatters can also have extra bonus uses but this should be explained in the slot’s info section.

3 Tips for Playing Online Slots
- Set your budget – Always set a budget before you start playing. Your budget should be cash that you’re willing to use and never money that you need to survive. By setting a budget, you’re on your way to being a responsible gambler.
- Read online slot reviews – Before you get started, make sure that you know everything about the slot you’re considering. Read our handy slot reviews for more information about paylines, volatility, the theme and more.
- Know when to stop – If you find yourself on a losing streak, resist the urge to chase down a win and rather step away. Play again another day and perhaps Lady Luck will be on your side.
