UK Casino – A site like Slot Boss with £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 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.


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.
