How Slot Machines Work
Modern slot machines are not based on physical luck alone—they are controlled by computer systems called Random Number Generators (RNGs).

Each slot game has reels filled with symbols such as:
- Fruits (classic slots)
- Numbers or letters
- Special icons (wild, scatter, bonus symbols)
3. Paylines
Paylines are patterns across the reels where matching symbols must land for a win. Modern slots can have:
- Single paylines
- Multiple paylines
- Thousands of ways to win
