Castle Jackpot – A site similar to Slot Boss with £10 free no deposit.
Another one of my favourite Slot Boss casino sister sites is Castle Jackpot. It’s a cool online casino that welcomes players with a generous £10 free no deposit bonus to spend playing online slots. Apart from the no deposit bonus there’s also a £25 free welcome bonus that it’s 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 limited of £50 cash. It’s truly 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 own money.
21 Casino – Another Slot Boss partner site.
If you’re fishing for freebies and lots of fun online video slot games, 21 casino is another casino site similar to Slot Boss which also offers all newcomers a free £10 no deposit bonus after registration. Much like any of the Slot Boss partner sites, there’s a wagering requirement of 99x 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 do want to play for real money prizes then there’s an unusual 121% free welcome bonus that can give you up to £300 extra to spend on the games. Slot games are powered by a mind-blowing number of brands such as NetEnt, Elk Studio, WMS, Thunderkick, Scientific Games and many more. 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. If you’d like to discover more casinos with similar features that offer a fun and secure gaming experience, have a look at the list of Pots of Luck sister sites with similar software, bonuses and games.
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 is different from other Slot Boss sister sites in that new players can get a £1 free no deposit bonus after registration. Getting just £1 free bonus seems cheap, doesn’t it? 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 10x booster bonus.
Pink Casino – A Slot Boss casino sister site for female players.
Our fifth option of the best sister sites to Slot Boss is Pink Casino. This gaming site has clearly been designed with the female and savvy player in mind. All new registrations to the site are eligible for a free £10 no deposit slots bonus for newcomers. As it is the case 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 huge choice of online slots, progressive Jackpots, casino and bingo games on offer. Powered by the best software in the industry, here you can play games like Starburst, the whole Rainbow Riches slots saga, Lucky Lady’s Charm slot, Golden Goddess slot, Action Bank, Cleopatra, Reel King slots game, Kitty Glitter, Fluffy Favourites Jackpot, the full Monopoly slots saga including Monopoly Big Event and Bring the House Down slots.

UK Casino – A sister site to win up to £50 no deposit bonus.
And our last choice for players looking for sites like Slot Boss is UK Casino. At this popular 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 it happens with other Slot Boss sister sites, there’s a limit as to how much you can win using the free bonus. In this case, players can withdrawal 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&C’s that they are “not obligated” to discuss player complaints.
