You described it perfectly. You can picture the game in your mind's eye. You just can t recall the name
They look like beanbags, so maybe the game is the one where you try and throw it through a hole in a board. Not sure what that game would be called.
Lots of fun games have been played with bean bags, but the ones in this photo belong to "Toss Across".
I checked out bean bags and this is all I could find: :)
