Summer Time Ring Toss

I don't know about you but my kids go stir crazy if they're in the house too long, but in the summer we can't go outside too much because they will burn up.  Not to mention that it is crazy hot!  I've been trying to get creative and bring outdoor activities inside without braking everything. 
Dutch got this ring & horse shoe toss set for his birthday and it has been the perfect game to play inside.  I simply stuck the posts into a can of play-doh and let the kids start throwing.  Not only can they throw these super light rings and horse shoes without braking anything, but it is also working on fine motor skills, hand-eye coordination, & getting some energy out.....it's a win for everyone! 
I can't find the exact ones that Dutch got, but these are similar.  What are y'all doing inside to get energy out of little ones and have fun?!?!
