When you go to see the game on the pirate101 website and then to mini games, the coin drop game is outdated. What I mean is, the picture of the coin drop game is different than how it actually is. It was probably a picture of the mini game before the game came out.
I think much of the images of the mini-games other than Coin Drop appear to be from the development version of Pirate101 before the changes were final for release. I think these images are quite out of date.
