Leo Vegas casino is the most popular Slot Boss partner site, offering one of the best gaming experiences online.

Incidentally, Leo Vegas was the first 100% mobile-friendly online site to offer a mix of the best slot software under the same roof. IGT, Microgaming jackpot games, WMS and Barcrest slots are all found here. It’s also one of the most generous Slot Boss sister sites featuring a whopping £700 free bonus welcome package.

Not to get confused, this bonus package gives you a 100% free bonus of up to £50 on your first deposit, but more bonuses follow once you’ve become a registered player at the site. If you like playing slots at Slot Boss, you will love Leo Vegas. Sign up today.

Castle Jackpot – A Slot Boss partner site with £10 no deposit.

A favourite Slot Boss casino sister site is Castle Jackpot, with a generous £10 free no-deposit bonus to play slots.

Another one of my favourite Slot Boss casino sister sites is Castle Jackpot. It’s a fantastic online casino that welcomes players with a generous £10 free no-deposit bonus to spend playing online slots. Apart from the no-deposit bonus, a £25 free welcome bonus is credited after you make your first deposit.

And just like you’d expect from any of the Slot Boss partner sites, there’s a wagering requirement of 99x your bonus amount with a maximum winning limit of £50 cash.

It’s not a bad deal if you fancy an offer that gives you a real taste of the action without forking out a pound of your money. We recommend visiting our Castle Jackpot sister sites review if you’re looking for more free no-deposit bonuses and a massive e-collection of online slots.

Pink Casino – A Slot Boss sister site for female players.

The best bingo site like Slot Boss and Pink Casino has the female and savvy player in mind.

Our fifth option of the best sister sites to Slot Boss is Pink Casino. This gaming site has been designed for the female and savvy player.

All new registrations to the site are eligible for a free £10 no-deposit slots bonus for newcomers. As with any other site similar to Slot Boss casino, the freebie does not come without some restrictions.

Expect to meet a wagering requirement of £990 before even dreaming about requesting a withdrawal. There’s a vast choice of online slots, progressive Jackpots, casino and bingo games.

21 Casino – A Slot Boss sister site with a 121% bonus.

If you’re fishing for freebies and lots of fun online video slot games, 21 Casino is another site similar to Slot Boss, offering newcomers a 121% deposit bonus up to £300.

Much like any of the Slot Boss partner sites, there’s a wagering requirement of 35x your bonus amount to deter bonus hunters from trying to make a quick pound without actually meaning to play at the site for real.

If you want to play for real money prizes, there’s an unusual 121% free welcome bonus that can give you up to £300 extra to spend on the games. A mind-blowing number of brands, such as NetEnt, Elk Studio, WMS, Thunderkick, Scientific Games, and many more power slot games.

You should know that many of the best slots are also available in a progressive Jackpot version if you fancy your chances of winning a crazy cash prize. The mix of slots software at 21 Casino is not unique, but it’s one that players love.

UK Casino – A site like Slot Boss with a £50 no-deposit bonus.

And our last choice for players looking for sites like Slot Boss is UK Casino. At this famous gaming site, players are welcomed with a free £10 no-deposit slots bonus that can be spent on slots, table games, and live casino games.

As with other Slot Boss sister sites, there’s a limit on how much you can win using the free bonus. Players can withdraw up to £50 in cash after meeting the wagering requirement while staking a maximum amount of £5 per spin. One reason for listing UK Casino as the last recommended option is that they have made it clear in their T&Cs that they are “not obligated” to discuss player complaints.

MCasino – A sister site of Slot Boss with a 10x booster bonus.

Players looking for a unique free no, deposit bonus offer should visit MCasino. This online casino differs from other Slot Boss sister sites because new players get a £1 free no-deposit bonus after registration.

Getting just £1 free bonus seems cheap. What’s different about this bonus is that it comes with a 10x win boost. This means that any winning combination you get from this £1 bonus will be multiplied by 10, thus giving you a chance to win a much higher prize and, best of all, tied to a wagering requirement of 99 x £1 instead of x £10 as it’s the case with the rest of the sister sites of Slot Boss.

Game-wise, you won’t miss anything. Slots here are powered by IGT, Evolution Gaming, Barcrest, Microgaming, NetEnt and even Novomatic. Create a new player account and get your £1 free with a 10x booster bonus.
