It's been like that for a while now, I agree! MG has no play time in it at all, I've said to 32Red on many occasions that it would not be that bad if you actually got some playtime out of your deposit! But as they say, they don't control the play, they are just at the mercy of MG. Hitting the bonus is harder to hit on 32Red than it is to on Golden Lounge I have found. I have better sessions on there sister casino than the 32Red one and has been like that for timeee. I've been thinking of going back to use Playtech software because I know at least I will get a good session out of it compared to MG.
If you're hitting bonuses more often at one Microgaming casino than another, that's random chance. I honestly don't believe any Microgaming casino's software is different from anyone else's. When I started gambling online many years ago I played exclusively Microgaming because I could get the play time for my money. That just doesn't happen anymore.
Deposits shouldn't be consistently dwindling to zero at minimum bet in less than 10 minutes. If it's going to cost 100 to 150x your wager to get a bonus feature you're wasting your time when the bonus features are returning less than 10x your wager when you hit them.
