I made 3 deposits to Vegas Regal Casino last week. On the first two deposits, I won about $500-$600, but I couldn't clear the playthru because the playthru on the deposit bonus I took was really high (65X). My third deposit was $55 with 300% bonus, 35X in playthru, and I was able to cash out the max of $715 from this deposit.
It's not new, game that won me big was once again Cosmic Episode 1, I had 3 rockets came out during the free spins for $1200 win. I had couple round of free spins prior to this big win, but they won me too little each time. I noticed that it happened like this most of the time with Rivals slots, some of us usually feel disappointed and change their games right away because the bonus win them too little.
So, if you like the slot, be patient, manage your balance and the slots might return you a favor.
