Free Online Slots

Here at Bonus Boss casino we believe that you should have the option to play on our inventive, high-quality online casino games for free, without the need to make a deposit into your account.

You’ll have the best time taking your favourite online slots for a free spin with our no deposit bonuses or choosing to hit the reels in Demo-Mode. No matter how you decide to play with Bonus Boss, the fun is guaranteed – no casino bonus codes needed!

Play our Online Slots for Free with a No Deposit Bonus

One of the best ways to play Bonus Boss’s online slots for free is to use one of our incredible no deposit bonuses.

These casino bonuses start from the moment you sign up and create your first account with us. You’ll get up to 100 free spins*, no deposit or casino bonus code needed, with our incredible Casino Welcome Bonus offer.

Existing players can also enjoy a no deposit bonus with our Refer-a-Friend offer. Simply refer a friend to our site and once they’ve signed up, deposited £10 and staked this through, you’ll find yourself with up to £5 in bonus credit** to use across any of our online slots games for free. There’s no limit to the number of friends you can refer, so the no deposit bonuses could keep on spinning in.

Each month a fresh, new online slots game takes centre stage at Bonus Boss online casino. To celebrate this launch a no deposit bonus offer usually runs alongside it, so that you can take these hot new slots for a free spin. There’s no guarantee what this no deposit bonus will be, so make sure to read the terms and conditions before you play.

Go for a Free Spin in Demo-Mode

When it comes to playing Bonus Boss’s incredible online casino games, you can choose to play the slots for free by using our Demo-Mode option. This gives you the opportunity to play for fun and visit the reels for free before deciding to make a deposit, or use one of your no deposit bonuses.

By UK law, playing our online slots in Demo-Mode works exactly the same as playing with a casino bonus, or real money, as Bonus Boss is licenced and regulated by the UK Gambling Commission. You can have the same fun in playing these free slots, however the credit that you use will be fake. It’s important to remember that you won’t be able to withdraw any winnings that you accumulate during Demo-Mode.

Exciting Online Slots at your fingertips

Once you’ve pick up a no deposit bonus, or decided to play for free in Demo-Mode, it’s time to choose which online slots game you’re going to take for a free spin.

All of Bonus Boss’s original online slots games are built and designed in-house by our award winning team. Each game is hand-crafted and packed with fun-filled features and mega multipliers, to bring you the best online slots experience around.
