I appreciate it when a site offers some sort of gamification beyond just the slots. I noticed that https://robocat-canada.com/ has a shop where you can exchange coins for bonus money or free spins. It is a nice way to get a little bit of value back from your turnover. You accumulate coins while playing and can spend them later. It feels better than a standard comp point system because you can actually choose what reward you want to buy. Just do not expect to buy the big prizes immediately.
