At Spin Rio we are committed to provide fair play at all times. Fair play is the base of our mutual prosperity. The games on this website are powered by software belonging to Aspire Global International LTD, a Malta based company which is a fully licensed operator (MGA/CL1/408/2007) under the Malta Gaming Authority. In Great Britain only, the games on this website are operated by AG Communications Limited, a Malta based company with registration number C48328 and having registered office at 135, High street, Sliema SLM 1549, Malta, which is licensed and regulated by the United Kingdom Gambling Commission (Remote Gaming License Number 000-039483-R-319409-001). To get a fair assessment of the expected return from playing a particular casino game, you need to look at the return to player (RTP) rating. An RTP of 97% equates to a return of £97 when you have placed wagers totalling £100. Spin Rio Casino has a good spread of RTP ratings. For online slots, you’ll come across RTPs generally around the 96% mark, but Spin Rio Casino has a good collection of games with RTPs of at least 97%. The jackpot section at Spin Rio Casino contains just over 16 different games. Some of these are progressive jackpot slots. While none of them have huge jackpots like you would find on other sites, five-figure pots are always on offer, with this sometimes reaching six figures. Some standout options include Mercy of the Gods and Divine Fortune.
