Slotland does have I think two video pokers and one unusual version of Blackjack, but it is mostly aimed at slot players.
The sales point for slotland is that they are good for any platform or browser. Many people who cannot play at other casinos because they have odd browsers can do so at Slotland.
Because of that, retention is superb.
People who love the speed of RTG are unlikely to play there.
Once people do play there, they are sent a newsletter monthly with the opportunity to win play money – outright. And they do – more often than not. This brings people back.
The pay affs a percentage of deposits – not losses as other casinos. That, too, makes them very attractive.
