Card Game for Bonding?

My aunties and uncles love playing poker. Actually, they are planning to spend this weekend again at my mom’s place so that they can bond through this card game. I know they have a rather unusual way of bonding. But you should see them play while they try to outdo each other with their own Texas Holdem Poker Strategies. They look so funny - like little kids playing. And right now I think one of them even have a new discovery. My Auntie Remy has found a Free Poker Calculator. She said that my uncles and aunties need to watch out for her No Limit Winning Strategy. Ergh! Sometimes even adults behave so funny. Could be regression? I hope not, but this is just their way of getting together and having great fun on a weekend.
