I recently had the pleasure of playing a family game of ladderball (aka bolo toss, ladder golf) using some basic homebrew hardware, and can say firsthand – it’s good times!
For those unfamiliar with the backyard sport: players throw golfball/nylon-rope bolos in attempt to hang them on a simple PVC ladder structure. It’s a surprisingly enjoyable “Ooh! So close!” type game in the vein of horsehoes/etc, and looks to be a straightforward build.
