Grandparents bought the kids a fire tablet each for Christmas. I've been asked to set them up for my girls and my sisters boy. The software isn't an issue, but what games/apps do I put on (preferably free ones as I have no idea yet how much they'll be used)? My girls are 10 and youngest is about to turn 7 in a couple of months My sisters boy is 5 Any help/suggestions would be great!!
