most of the time it goes right down as soon as you meet the cashout requirements on Rivals..couple times Club Vegas cashed out 1000+
had it up to 2400 once, 2200
Absolute Slots, Same thing..2200, but only cashed out 500

but as far as you question goes...I could have cashed it out at the 2200 if I wasn't having fun.
Microgaming Casinos much better luck..have started out very low, and cash out thousands. Much easier to win more with larger bankroll, than a Rival Gaming Casino
