Funnily enough, I find Microgaming is converting the best for me – a complete switch.
Used to be RTG, but they are totally sucking with the exception of Adriches, which continues to convert well.
Roxy rocks – and has the best marketing materials IMO
Casino Partners has a great % conversion rate so far.
Fortune Lounge is a steady performer and player retainer – grows each month for me.
Money Mechanic is improving.
Vegas Affiliates convert very well and has good player retention.
Casino Rewards is steadily improving.
