Search run 21 instead. This would be a great game if you could play it more than a few times without having to pay. After only a few games you either pay or wait hours to be allowed to play again. I mean four or five games and that's it? And the coast for a few more games if ridiculous. Uninstalled.

It is okay. I have noticed that if you try to play the bonus lane more than a few times is when it will bust you every single time. At least they do the 5 card win if it isn't a bust, which many others do not even have that rule.

It's kind of sad ...The game itself is very good ...when it comes to your money (wow) not good. Example. 10 mins ago ..in a 30$ tournament. Was at the end of the game had a good score, the app crashed. Instead of posting my score ...it aborted me.. Contacted support,. Was told if they can't find a player to play in 7 days I'll get a refund ..So I just lost 30 bucks and not the first time...I'm done ( made a withdrawal What was not aborted ..deleted app..will happen to you also if you deposit.
