Perhaps this is the future of casinos. Imagine having exclusivity for a specific game, and if it were successful, casinos would have a ton of customers almost guaranteed.
These exclusive game can easily be copied by different casino and modify a bit just to avoid copyright issue. Exclusivity is very hard to apply in online casino since gambler preferred the payout and bonuses rather than the game mechanics itself.
If casino offers huge bonus with easy requirements for sure it will attract many players even with the shittiest games.
