It's not easy. We tried slamwich - my dad hated the slapping part. We played "MMM...Brains" and that one went over a little better although we think the rules need a bit of elaboration about phase 2. At Thanksgiving we tried Apples to Apples and that didn't go over. Maybe with a bigger crowd.
Still to play - Monkeys on the Moon.
Games they do like - We did play Quiddler and 5 Crowns - those are long time favorites. And dominoes.
