We have thought long and hard about doing a "deposit bonus" but after going back and fourth with our developer we decided it is now in our best interest, since it can easily be abused.
We have also thought about doing Royal Flush and 4 of a Kind bonuses on the ring games. Would anyone else be interested in this and would it encourage you to play more on the ring games? If so we can possibly get this implemented.
As someone who's constantly looking for action in the ring game section, I'd love to see it. Not only if I get a prize but because I'd also be happy to find more folks playing there to join in.
