Slot Machines
Online slots are the most-played casino game category. They run on Random Number Generators (RNG) and come in dozens of mechanics — from 3-reel classic to Megaways with over 100,000 ways. Live game shows like Crazy Time count technically as a slot/specialty variant with a live-dealer element.

Overview
- RTP (Return to Player) tells you how much returns long-term — typically 92–97%.
- Volatility describes the risk profile: low = frequent small wins, high = rare big wins.
- There are no 'hot' or 'cold' slots — every spin is independent.
- Mechanics (Megaways, Cluster, Hold & Win) change feel, not the underlying math.
Rules
How to play

Tips & Strategy
- No 'strategy' beats the RNG.
- Bankroll management is the only relevant discipline.
- Bonus rounds don't change long-term RTP.
- On jackpot slots: base RTP is usually lower; the jackpot share offsets it.
