How Slot Machines Work
Random Number Generators (RNGs)
Modern slot machines use complex algorithms called Random Number Generators to determine outcomes. These ensure:
- Each spin is independent and random
- Results are not influenced by previous or future spins
Return to Player (RTP)
- RTP is the theoretical percentage of wagered money a slot will pay back over time
- Typically ranges from 88% to 98% depending on the game and jurisdiction
Volatility
- Low volatility slots offer frequent small wins
- High volatility slots offer less frequent but potentially larger wins
Popular Types of Slot Machines

The Psychology of Slot Machines
Slot machines are designed to be engaging and sometimes addictive. Understanding the psychology can help you play responsibly:
- Near misses: When the reels stop just short of a winning combination, creating the illusion that you almost won
