Why Learn the Terminology?

Walking into the world of online gaming without knowing the lingo is like reading a book in a foreign language. Once you understand the key terms, game guides make more sense, you make smarter decisions, and you get far more out of every session. Here are 25 essential terms to get you started.

Core Game Terms

  • RTP (Return to Player): A percentage indicating how much of total wagered money a game returns to players over time. A slot with 96% RTP theoretically returns $96 for every $100 wagered.
