We explain what a slots bonus is and how to maximise it. We also reveal where you can find the latest online slots bonuses at JeffBet to add to your casino bankroll.
What is a Slots Bonus?
An online slots bonus is a casino promotion that gives you cash or spins for selected slots. When you deposit money at JeffBet, you may unlock a match promotion or free spins for much-loved Pragmatic Play or Play’n GO slots.
All slot bonuses come with terms, conditions, and wagering requirements, but they’re a good way of increasing your bankroll while playing your favourite games.
How Does an Online Slots Bonus Work?
At JeffBet, we offer several slots bonuses, so they each work slightly differently. That said, the steps below reveal how a slots welcome bonus works to show you how to access it:
- Register for a JeffBet account by clicking JOIN NOW.
- Head to our PROMOTIONS tab to check for the latest offers and to read the T&Cs.
- Visit our cashier to make the minimum deposit (usually £10 or more) to activate the deposit match or free spins offer.
-
Check your balance to confirm the bonus has been added. If not, visit our Help Centre to contact a customer support agent.
- Use the search bar to find the slot you can play with your bonus cash or spins.
- Spin the reels with your free spins or bonus cash for a winning chance.
- Satisfy the wagering requirement (35x to 50x, depending on the offer) within the given timeframe (usually 30 days).
- Cash out any winnings from the bonus via the JeffBet cashier.
Online Slots Bonuses at JeffBet
We regularly refresh the online slot bonus options at JeffBet to deliver great-value gaming to all our customers. Here’s an overview of the offers you might be eligible for at JeffBet, with examples of each (please check our promotions tab for the latest deals):
Slots Sign Up Bonus
We offer all new JeffBet customers a slots welcome bonus. Registering and making at least the minimum deposit may result in a deposit match promotion plus free spins.
For example, an initial deposit of at least £10 or more could activate a 100% deposit match up to £100, plus free spins on top slots like Book of Dead by Play’n GO.
Free Spins Reload Bonus
We frequently offer free spins reload bonuses to JeffBet customers. To activate the promotion, you must opt in and deposit with a promo code.
For instance, deposit at least £10 with a limited-time promo code on a specific day of the week to receive 25 free spins for selected Pragmatic Play games. The required promo code and all T&Cs are on our promotions page.
Mystery Box
One of our most popular ongoing promotions is our Mystery Box. You can unbox up to 100 free spins for selected games from Monday to Thursday.
Typically, you must deposit at least £20 with the relevant promo code to have a chance to open the Mystery Box. Inside, you will find 25 to 100 free spins for some of the best slots at JeffBet.
Midweek & Weekend Wheel of Spins
At JeffBet, we also offer spins on our special bonus wheel. Again, you must opt in for this promotion and make at least the minimum deposit with an authorised bonus code.
For instance, if you deposit £20 or more with a promo code, you’ll receive one wheel spin that could add five to 500 free spins to your JeffBet balance.
Slot Competitions & Tournaments
We’re big on gamification at JeffBet. You can participate in regular slot competitions and tournaments to get a share of significant prize pools.
You must opt-in, deposit, and play participating games to win. Then, if you rank at the top of the leaderboard, you’ll receive a share of free spins or cash prizes. We also participate in Pragmatic Play’s Drops & Wins network, letting you play some of the studio’s top-rated games for bigger prizes.
