The gameplay is pretty much just a weird slot machine with a giant Mario with an "F" on his hat in the middle. You might want to note that this character looks nothing like Mario. You spin (I think the game does it for you. I can't tell), and if you get anything, Mario hits a block over his head and gets coins.
The graphics are okay, until you look at Mario. He's just downright scary. Take a good look at him. His huge nose, strangely blue eyes, weird legs. His incredibly happy grin. Everything about him is incredibly fucked up.
There's no music, and pretty much the only sounds are the spinning and coin-collecting, which I can happily say they hit dead-on!
