I play lumosity - the brain challenger games- the free one of course and it's loads of fun. Your brain will be moved in different ways. I also do games on Facebook with people from around the world. One I really enjoy is Texas Holdem Poker. Another mind bender is Pyramid Solitaire! I play with 70 people. The good thing is you don't have to play friends, you can play with anybody. Want a fun game and so cute, with adorable music? - check out Panda Pop, my granddaughter introduced me to this game and it's another favorite!
want to battle MONSTERS? Yes, big ugly monsters- yes, they are tricky- but you have help, weapons- Monster Busters-!
This game is a real mind Bender in soooooooo many ways,a real challenge- Lost Jewels-
I also like Pet rescue Saga, it's a cute game trying to rescue pets, dogs, cats, etc.
Dont like Facebook- well just play games like I do- you don't have to socialize- just Retrain Your Brain and Have Fun doing it!!!!
oh, one last game you can play with your grandchildren, Truth or Dare, you can do it however you like and We All Love it! Improvise!! It's an App.
