He assured me that an independent lab did tens of thousands of spins and the probability of the two balls landing the same number is about the expected 1/38, assuming they two outcomes were completely independent. At least I wondered this and annoyed the game maker with physics questions at the gaming show for much too long about it. You might also wonder if the probability of the two balls landing in the same number is about the expected 1/38, assuming they the two outcomes were completely independent. They travel at the same speed so the second ball always trails the first one. The game uses compressed air to shoot the two balls out of a tube almost simultaneously. You might wonder about how they keep the balls from hitting each other in a physical game. Later, in November, 2016, I noticed it at an Internet casino using Felt software. I first saw the game at the 2013 Global Gaming Expo and later at the Tropicana in Las Vegas on February 18, 2014.
