Best Slots Bonus - Updated December 2023

Slot machines lack the glamour of poker and the furore of craps, but the jingling sound of one-armed bandits is ever present in UK casinos. These games attract more players than any other, and that’s even more true online, where they account for the bulk of the average casino’s games.

If you love slots as much as everyone else, this is the guide for you. We’ll look at some of the best slot bonuses that you can collect, as well as the places you can find them and ways to get more out of them.

What are the Types of Slot Bonus?

Slot bonuses come in many shapes and sizes. These promotions all differ with regard to their terms and conditions, as well as the extent of the offer, but they are all focused on slots.

 

No Deposit Slot Bonuses

No deposit bonuses are easily the best type of slots bonus…if you’re a small-stakes player.

These bonuses give you a set number of spins without requiring a deposit. The wagering requirement is usually quite strict (see below for more information), and you often only get 20 or so spins.

Still, free is free, and these bonuses are a great way to introduce yourself to a casino.

The reason they don’t work so well for high spenders is that those 20 spins likely have a value of just £2 or £5, which won’t appeal to someone who deposits a greater amount.

Free Spin Deposit Bonuses

High spenders will be more interested in these offers, as they can provide upwards of 100 and even 500 free spins.

Free spin deposit bonuses require a deposit and usually provide you with a mixture of spins and credits. The spins are often fixed while the bonus credits are based on your deposit.

Take the following as an example:

100% Matched Deposit Bonus up to £500 + 100 Free Spins (Min. £10)

This is just an example, but it’s the sort of bonus you’ll see on countless UK casinos.

If you deposit £10, it will be matched 100%, giving you another £10 in bonus credits. If you deposit £100, you’ll get £100 while a deposit of £500 or more will give you £500 extra.

In all cases, you’ll also get those 100 free spins, as you’re meeting the £10 minimum requirement each time.

The spins are fixed to just one or two games, the most popular of which include:

• Gonzo’s Quest
• Fluffy Favourites
• Starburst
• Rainbow Riches

Reload and Loyalty Slot Bonuses

Reload bonuses are bonuses that encourage you to “reload” your account with cash. When you do, you’ll be given a bundle of spins/credits. 

These bonuses are targeted at active players. The most loyal players can also join loyalty programs.

Loyalty schemes give players points every time they play. They can then either swap those points for free spins or earn a bundle when they hit a certain milestone.

Loyalty programs take this idea to the next level. They are reserved for the high spenders. Some of them give you access when you make it to the end of the loyalty program while others are invite-only, with those invites limited to players who deposit and wager large sums on a regular basis.

Real Money Slot Tournaments

Slot tournaments are available at many top UK casinos. They give players an extra incentive to spin their favourite slots by awarding a series of prizes, including free spins and bonus credits.

Tournaments run for a fixed period, either a few hours, a few days, or a month. During that time, players earn points when they wager a minimum sum on a qualifying slot machine.

The players who collect the most points will climb to the top of the leaderboard. 

Slot tournaments are fantastic when the points are based on win percentages. It means the player who wins £100 from a £0.10 bet gets the same points as the player who wins £10,000 from a bet of £10.

However, some tournaments award points based on the total amount won, and these are only worthwhile if you’re a high roller.

What are the Terms and Conditions of Slot Bonuses?

Before collecting a slot machine bonus, be sure to check the terms and conditions. There are a few in particular that you should look out for:

• Minimum Deposit: All deposit bonuses have a minimum deposit requirement. If you fail to deposit this amount then you won’t be given the bonus. Most deposit limits are fixed at £10 or £20.
• Spin Value: How much are the spins worth? This is something that many players overlook. They lose themselves in the total number of spins and forget about the actual value.
• Qualifying Slot Machines: Are the spins fixed to games like Starburst and Fluffy Favourites? Are they available on all of the casino’s games? A slot bonus is only worthwhile if you actually like the slot, so make sure you check this requirement.
• Withdrawal Limits: Slot bonuses often have a win limit or a withdrawal limit. These limits prevent you from winning above a certain amount. Your winnings won’t be void if you exceed this amount, but you’ll lose all of the funds over the maximum.
• Wagering Requirements: Most bonuses require you to wager the funds a specific number of times before they can be withdrawn. Where free spin bonuses are concerned, the wagering requirement applies to the winnings. So, if it’s fixed at 10x and you win £10, you must wager £100 before you can withdraw.
• Payment Methods: Many casinos exclude payment methods like Neteller, Skrill, and PayPal from their deposits. Even if you meet the minimum deposit amount, the bonus will be void if you use these methods when the terms and conditions exclude them.

There may be some other requirements to look out for as well. Check the full terms and conditions to learn more.
