Yes, Poker is one interesting game that we can play in our leisure time. I just remember a long time ago when Zynga poker is very popular in my place where we always play anytime in anywhere, which means If stake can make that Poker is enough friendly to us and also able to play on mobile phones, I really sure they can get the market for all people without exception. I hope they can prepare it carefully, and focus on the development of mobile phones like Zynga, and create a lobby with can play with a minimum bet like $0.1 just for fun.
