If Rummy is your game, Rummy Royal is definitely the place you should head to for some online fun. Based on Cyprus, this site features 30% rakeback, and a sign-up bonus of $200, which is in fact a 100% match on your deposit up to the above named maximum.

The bonus is valid for 60 days, and it is released in $10 chunks. Mind you, this is a rummy rakeback deal and not a poker one.
Rummy is considered a game of skill and therefore U.S. players are accepted too.

Rummy Royal features Gin Rummy, Kalooki, Traditional Rummy and Oklahoma.
