Grate Guy's Casino

Grate Guy's Casino is a secret level in Super Mario RPG: Legend of the Seven Stars. The casino is run by the jester Grate Guy, and can only be accessed with a Bright Card acquired from his partner Knife Guy.

The casino can be entered through a secret passage in Bean Valley. In one of the pipes in the center of the valley, Mario has to defeat a Chomp Chomp and jump three times to make an invisible platform appear, which opens the way to the casino. Mario can get hints how to find the casino from a sleeping Toad in Nimbus Land's inn.

One game available is the slot machine. Mario has to set a number of coins, then hit a Treasure Box three times, stopping it at the same symbol each time. If he manages to, he gets awarded a Frog Coin.
