I first came across this game while stuck at the main train station in Ostrava waiting out a two-hour delay. Was bored out of my mind and browsing casino reviews on Reddit. Saw people talking about plinko as a low-stress way to pass time. Tried it on my phone and it turned out to be the perfect thing. Super simple, just drop the ball and watch. I had no expectations but walked away with a few thousand CZK more than I started. Made the train delay almost worth it.
