You mean there are token rewards for playing these games as cashback? Just asking to confirm 
Yes, that’s correct. You will get 1 GLX for every $10 you spend (wager) playing slots or original games and for all other games you will get 1 GLX for every $20 you wager. Based on the number of GLX tokens you hol, you will als receive devidends from the devidend pool.
You can read about how all of this work on this page:

They also offer a calculator that helps you calculate how much you can earn based on the number of tokens you own.
Don’t forget that you will need to be rank 2 (wager of 1000$) before you will be eligible for dividends. While the team has their reasons for it, I am not the biggest fan of this (no other dividend casinos have such a requirement). The dividends they pay out, are quite nice and if you are a high roller you will be able to obtain a nice amount of tokens quite fast.
