Our expert team at Bonus Buy Slots have put together some exclusive research to produce a guide around the best RTP (Return to Player) slots that are currently available.
Slots that have a high RTP return are much more attractive to casino consumers and the casinos themselves, as these are much more popular all round. This is due to them giving players a much greater chance of winning each time. RTP is calculated by the average return that is paid out over time on the specific slot game. This means it is not guaranteed over a smaller sample size or time frame and these statistics are based on all-time play over a long period of time for everyone.
One example of this in play. If a slot game has an RTP of 95%, then if you bet £100 and you can expect to get around £95 back on average. However, remember that this is over time and chances of winning can be much less and more, so this is really important to take into account.
High RTP slots are widely available at Bonus Buy Slots and you can find our current exclusive list of the best ones available here:

1. What does RTP mean in slots?
RTP means return to player. This is the overall percentage that is paid out on the slot game or machine that is expected to be paid out to players over a long period of time.

2. What are the different levels of RTP in slots?
When it comes to RTP slots and they are simply divided across two sections. These being high RTP slots and then low RTP slots. Each will have it’s own unique positives that drives players to them but if you are looking for a safer and long term gamble and the high RTP slot will always be the option.
Low RTP slots usually range from between 85-93% of a return, in comparison to high RTP slots, which are usually around 94-99%. However, some of those lower RTP slots can have a much higher potential winning return, which is important to take into account.
