Thanks, guys!
Now I am as undecided as before 
Mike, with Bingo you need patience. Players tend to play for free for extended periods of time – until their chat partners win a jackpot or some such thing. Then they start depositing and continue to do so – very loyal players. I am mostly concerned with signing up as many fun players as I can. Then I just wait for the conversions to kick in.
I wouldn’t drop Bingo Hall – those 24 will likely still give you nice conversions. Add to them. The more the merrier.
I have the most paying players at Bingo Reward
Anyway, while Favorite Bingo somehow seems a good one, Bingo Chatter sounds more brandable.
I will want to brand this site.
