A Guide to Casino Bonuses

A casino bonuses blog wouldn't be complete without a complete guide to claiming the fantastic bonuses that you can receive as a new or existing customer. Check out how you can claim our bonuses here.

Guide to Jackpots

Progressive Jackpots Guide

We've had a fair few questions asking what a Progressive Jackpot is, how it works and we've had a number of sub-questions regarding the topic. Therefore, we've created a blog dedicated to providing our players with all the need to know information for the popular bonus.

Casino Bonuses Guide

Free Spins Bonus

Free spins casino bonuses offer a number of free spins on a selection of casino games. When you meet the criteria for the free spins, they are credited to your account to be used - usually within three days. If you don't use them in this time, the free spins are forfeited, so be sure to check the terms and conditions of free spins offers. Free spins bonuses are a great introduction into slot games for novice players before wagering real cash.

When you sign up for a new account and register a valid debit or credit card with Slot Boss, you will be credited with a £10 free no deposit bonus. This is credited to your account simply for registering and adding your card. 18+, begambleaware.org. T&Cs apply.

First Deposit & Cash Match Offers

First deposit offers are limited to new customers making their first deposit after registering. Opt-in or look for a promotional code to be eligible for a first deposit offer. The first deposit offer matches your first deposit up to a set value. Once you have deposited and wagered a certain amount, your deposit will be matched and paid into your bonus/promotions account to be used online. The amount returned to you cannot be immediately withdrawn, it must be wagered a certain number of times first. The bonus will only match the very first single deposit made. The larger your initial deposit, the larger your bonus will be!

New players at Slot Boss can unlock a 'first deposit offer' of up to £200. Once you have registered, simply make your first deposit of up to £200 and play our online slots. We will then match your deposit up to £200. The deposit bonus is credited to your account once your deposit has been wagered 30x. It is a cash reward that can then be withdrawn or played with. This is a great offer, particularly if you’re a player who wants to try a range of games or play your favourites more than just a handful of times, as it effectively doubles your money to play with.

As well as welcome offers for new customers, we also offer a number of casino promotions to our existing players.

Slot Of The Week

Slot of the week promotions offer a bonus return on a nominated slot game. Opt-in and meet the eligibility criteria to be rewarded with your bonus free spins. The free spins can be used on the promotional slot of the week, boosting your chance of receiving a payout.

Each week, Slot Boss selects a slot game as Slot of the Week. Opt-in on our promotions page and wager £20 on the promotional slot game. Once you have met the wagering requirements you are automatically credited with 10 free spins to be used within the designated time frame. Unlike many other casinos, any winnings from the free spins with the slot of the week are paid directly to your cash balance to be withdrawn or played with.

Now that you know more about the different types of casino offers available, you can choose to take up the ones that best match your playing style. We like to reward all our members, not just new players, so once you have registered, remember to check our casino promotions page regularly to keep up to date with the latest special offers and bonuses. Plus, we will be updating our casino blog regularly, providing analysis and insight into slots and live casino games.
