I usually plays cards game with my friends , there's a lot of varieties in card games. It varies on country . I started playing the poker game online and also learnt how to play online. I didn't have the luxury or chance to play it on offline casino or woth friends. So currently I was thinking, if I wants to play it for fun with out cash involved how can I start this game. I don't have the chips.
So without instrument how can we start to play this games. 
Because of your thread, I tried to find a poker game I used to play on Facebook, and that is ZyngaPoker. I saw that this game was already available on the Play Store (for Android), and on the App Store (for iOS). So, I thought you could try it to understand how the game works as you need. I noticed they still offer daily free chips to play with every day. So, please give it a try.
Here is the source :
zyngapoker.comBy the way, I also ever played poker on my old PC, and If I am not mistaken it was from Gamehouse (I think everyone with a Windows Vista, XP, or 7 PC has played it), and the name is "Casino Island to go". Unfortunately, I didn't find the official source, I am afraid to give a dangerous source to share.
