Haven’t had much luck with Tower Gaming and Casino Luck, but I haven’t got anything bad to say about them. Probably my own fault.
AffiliateLounge is THE NetEnt affiliate program. As I recall it, NetEnt was owned by the group behind Affiliate Lounge, Betsson Group, but now they have same majority shareholders. Unfortunately you can experience slow support, and I believe they have a minimum quota-rule which is a no go in my opinion.
Have you checked VeraJohn (multible software suppliers), NordicBet (NetEnt + MicroG (for Danish players) and Unibet (NetEnt + MicroG)? Good programs too, in my opinion!
