Which tablet should I buy? Fire, iPad, Kindle?

I am 58. I mostly want to use it for a good Scrabble game, maybe backgammon, and someday reading books (when the eyes start to go). Ok, the eyes are starting to go. So, large print, large screen, and best simulates a book experience. I am relatively tech savvy. Us an Apple for my business and a good old fashioned, mega-pc at home.
