Welcome to the Luxury Tax space, one of the least visited spaces on the game board.
This is an interesting space on the board because it seldom has much of an impact in the game. When players land on it early in the game, they usually react with "What luxury?!? At least it is only $75." Later in the game, when their finances may be a little bleaker, the space serves as a subtle way for the game to knock a player who may already be down!
Anyway, just like in the game, this cache is a rest spot while doing the series. No need to collect any info or work out any puzzles. Just pay your $75 and grab your smiley!
Finally, here's a little piece of Monopoly trivia for you, from the Hasbro Gaming website:
Since 1935, more than one billion people have played the game.
