Online slots work in a similar fashion to classic casino slots. These may feature free spins, re-spins, pick-one bonuses, or trail features. Some slots also use cascading reels, where winning symbols disappear and are replaced by new ones, potentially triggering multiple wins in a single spin. RTP (Return to Player) is the percentage of total wagers a slot returns to players over time.
For example, a slot with 96% RTP will, on average, return £96 for every £100 wagered across a large number of spins. Higher RTP values generally indicate better long-term returns, though results in any single session will vary. Volatility describes the risk profile of a slot game. Low-volatility slots pay out more frequently but in smaller amounts — better suited to longer, steadier sessions. High-volatility slots pay out less often but can deliver significantly larger wins when they do.
Understanding both RTP and volatility helps you choose a slot that fits your playing style and budget.
Each spin will activate a number of reels, revealing potentially winning symbol combinations once they’ve stopped spinning. Each online slot consists of a number of reels, with a set number of winning combinations to play for. Some games even include bonuses like Free Spins, Wilds, Scatters, Jackpots and other unique in-game features. The most popular online slots include many in-casino classics, such as Rainbow Riches, Cleopatra and Book of Ra. Our Grosvenor Original game, Buffalo Wild, has proved an instant classic and has already made it to fan-favourite status.

Megaways is a trademarked game formula that uses a unique Random Reel Modifier algorithm to change the number of rows active on each reel with every spin. This means potentially more winning combinations are in play with every spin. Some Megaways games offer up to 117,694 ways to win. The nature of Free Spins will likely vary depending on the game you’re playing, and if you’ve earned them in-game or through a promotion. Classic slots are inspired by traditional pub fruit machines. They feature familiar symbols — fruits, BARs, and sevens — alongside simple payline structures and beginner-friendly rules. If you prefer a no-frills experience, classic slots are a great place to start. Video slots are the modern evolution of the classic format.

Most online slots feature Free Spins as part of an in-game bonus offering, and using Free Spins is as simple as spinning the reels during regular play. Online slots usually like to highlight when you’re using a Free Spin. You’ll also find frequent promotions on offer with Grosvenor Casinos where Free Spins are up for grabs. A Wild symbol can fill in for any other symbol on the reels. A Wild can be adapted to complete a winning payline.
Wilds typically don’t substitute for Free Spins, Scatters or other bonus symbols. Scatter symbols can appear outside of a winning line, but still register as part of a winning combination. This enables wins beyond the typical win lines. Combinations of Wild and Scatter symbols are sometimes used to unlock in-game bonuses, but this differs with each online slot. You can play slots online via mobile using a smartphone or tablet.
