I believe that real money slot machines have their advantages, such as the possibility of winning real money and the excitement they bring. However, they also involve the risk of losing money and many people have gambling addiction problems. On the other hand, I think free social casino is much better, especially if you are a newbie and are just getting familiar with the world of gambling, then free slot machines are perfect. Also, free slot machines provide a great opportunity to have fun without the risk of losing money. They can be accessed by everyone and players can enjoy the game without any commitment. 

Real money slot machines can be exciting, but also dangerous in terms of financial stability. Free slot machines provide great entertainment, but their microtransactions can be an ambush for uncontrolled spending. The key here is moderation and the ability to control your actions. Real money slot machines should be used with caution and responsibility, and free games should be used as entertainment, not as a way to make a profit.
