I was on a cruise ship last week, and they had these machines where you put a coin in one of 3 slots in the front, and it spits it up onto a ledge with little things that sweep the coin into a pile of coins, and those eventually get pushed down another ledge, where the same things happens, except the bottom part is much bigger and when it falls off that ledge, you get the coins that fall down.
Does anyone know more about these? The boat had put some bills and chips in the mix, although the brick of 50 $1s moved way more slowly than you would think it would. It seems +EV if enough people have put coins in or pushed the prizes closer to the ledge, but I saw them open the machine at night. I didn't see exactly what they did, but it looked like they were taking coins out, which makes sense. Not sure if they moved the brick of $50 back overnight, it looks like they may have moved it slightly, but at the end of the cruise, they moved it all the way to the back of the machine again. A pit boss said they didn't move it overnight but did after the cruise, which would lead me to believe noone ever wins it, although it did look like it had moved slightly overnight.
Ah, great article, thanks!
The Nugget in downtown reno has a quarter machine of this game.
