Is there any game that pays real money without deposit for free?

I'm curious, have you come across any legitimate games that offer the promise of earning real money without requiring any initial deposit or investment? It's a tempting prospect, but I'm skeptical about such claims. After all, many online scams and fraudulent schemes prey on individuals seeking easy money. So, are there any reputable games that genuinely allow players to win real cash without having to put anything down upfront? If so, how do they work, and what precautions should be taken to ensure one's safety and security while participating?
