I have actually sent my parents links throughout these years for games we can play outside. My dad made a variation of Corn Hole, except with one hole, there are 3 different size holes & he made legs that can come out so they can be angled. They also got beans to sew into baby socks (it works!). He has a set for outside that gets dirty but they also have one for inside they play at times. He made one for us as well.
We haven't tried yet but there is Lawn Bowling with plastic water or pop bottles. Jenga. Dice. Dominoes. Twister.
