There are a few different opinions on whether or not Monopoly slots are actually free. Some people believe that the game itself is a form of gambling, and as such should be considered a form of gambling. Others believe that the game is just an amusement, and as such should not be considered a form of gambling. While it is technically possible to play Monopoly without spending any money, most casinos will allow you to purchase in-game credits which can then be used to play the game.
It is important to note that while some casinos may allow you to play without spending money, others may only allow you to use in-game credits. Ultimately, it is up to the particular casino that you are playing at.
