High bonuses can work wonders when you get a whale swimming by – they will go for the huge bonus and forget about the freebie that lets them spin the slots a couple times.
So I have had some good redults with these, but as a rule I like to keep them at a reasonable level. There are times though when a casino wants to attract a bunch more players, and the results should show up in following months if the players continue to play without the huge welcome bonus.
Like Gooner said, these are welcome bonuses, not manager credits applied at will. It’s the manager bonuses at some RTG casinos that kill all revenues..
I would wait a month or so and see what happens with the new players this promo brought in…
