How Casino Free Spins Bonuses Operate

Free spins are often awarded when you create a new account or make your initial deposit at an online casino. In the UK, these are increasingly called "bonus spins" to align with regulations set by the UK Gambling Commission.

Typically, these spins can only be used on selected slot games, frequently to showcase new releases. A classic example is NetEnt’s Starburst—a bright and straightforward 5-reel slot that’s especially appealing to newcomers because it resembles popular casual games like Candy Crush.

Other slots regularly featured in free spin deals include Gonzo’s Quest, Twin Spin, and Dracula. Major providers such as NetEnt and RTG often offer these promotions. At BritSpinAdvisor, we constantly review the newest slot games, so stay tuned for updated free spin bonuses.

The amount you win from free spins usually depends on the stake value assigned to each spin. For example, winning from spins valued at £1 each tends to be more rewarding than those at £0.01. The exact spin value is outlined in the bonus conditions—so 25 spins at £1 each could be more lucrative than 100 spins at £0.10 each.

To get started, register at a casino or make a qualifying deposit. After logging in, open a slot game eligible for free spins. A notification will often pop up, letting you know your free spins are ready. Just click ‘spin’ and see if fortune is on your side!
