Operated by the Jumpman Gaming Group, RainbowSpins is the sister site to Amazon Slots and Loot Casino. It is available on all major platforms, including Android and iPhone and the Rainbow Spins casino is effective in both desktop and mobile versions.

Rainbow Spins: Scratch Cards and Roulette Games

Scratch card devotees are well looked after on Rainbow Slots, with a decent number of options. Queen of Gold, Hot Safari and Prince Treasure are among the options, with prizes of up to £100,000 on offer.

As with other Jumpman UK gambling sites, the Table Game section on Rainbow Spins is not world-beating. Roulette players have a few choices, with the Live Speed, Auto and 20p varieties in place and Blackjack nuts will enjoy the Atlantic City, One and European tints to their favourite game. But, in general, the Table Game offering is not very comprehensive and is certainly not the strength of the of the site. 

The “Casino” chapter of the navigation tool strongly evidences the Celtic vibe, with Gaelic Luck, Lucky Emeralds, and Leprechaun’s Luck all examples of that ilk. Mind you, with a name like Rainbow Spins, we shouldn’t be too surprised by the themes or the slot-heavy offering. 

Responsible Gambling

Rainbow Spins takes safer gambling very seriously and there is plenty of help on the site for those concerned about their gaming habits. From setting deposit limits to taking time-outs, there are tools available. There are also links to national gambling helplines, such as GamCare and Gamblers Anonymous.
