* **No Real Money Wins:** You cannot win or cash out real money. It’s purely for entertainment, practice, and understanding the game.
* **Virtual Balance:** You’ll play with a simulated balance (e.g., 10,000 demo credits) that resets when you refresh the page or reload the game.
* **Not All Games Are Available:** Some licensed branded games (like movie-themed slots) might not have a public demo due to licensing restrictions.
