Casino Videoslots gives fewer rewards/bonuses to high rollers?

Just noticed that when I use to deposit smaller amounts like $50 - $100 and made smaller wagers, I would frequently get offered x2/3 CashBack and sometimes free spins.

In the last 2-3 weeks, I started depositing/wagering more. At other casino like 32Red Group, FortuneLounge and VPL (can't remember all the names) I started receiving better bonuses offers....Actually there weren't necessarily better, but they were higher (ie. instead of 50% bonus up to $100, it would be 50% bonus up to $1000).....

VideoSlots went in the opposite direction. The only reward I've received this past week is a 10% match bonus up to $10. Not even worth the time to read/adhere to the T&Cs that must go along with it in my opinion.

Is VideoSlots giving out less Rewards to everyone? Maybe their going downhill idk???

Perhaps the better Reward offers to low-rollers (or new members) are just there to try and encourage them to deposit/wager more, but once they do, the Rewards stop??? Interesting strategy perhaps!
