🔍 Understanding the Results
RTP (Return to Player)
The percentage of wagered money a game pays back over millions of spins. Higher RTP = better for player.
House Edge
The casino's advantage = 100% – RTP. The lower, the better your chances.
Expected Loss per Bet
The average amount you lose on each wager = Bet × (House Edge/100).
Expected Loss over N Rounds
Multiply per‑bet loss by number of rounds to estimate total expected loss.

You play a slot with 96% RTP at Rivers Casino Des Plaines, betting $1 per spin. Expected loss per 100 spins = $4. Manage your bankroll accordingly.
Example 2: Online Blackjack Player in Springfield
Using basic strategy at a legal IL online casino, RTP is 99.5%. With $10 bets, expected loss per 100 hands = $5. Much better than slots.
❓ Frequently Asked Questions
What is RTP?
RTP stands for Return to Player – the percentage of all wagered money that a game pays back over time. For example, a 96% RTP slot returns $96 for every $100 wagered in the long run.
What is house edge?
House edge is the casino's advantage: 100% – RTP. A 4% house edge means the casino keeps $4 of every $100 wagered.
Are online casinos legal in Illinois?
Illinois has legalized online sports betting, and online casino legislation is under consideration. Many players use offshore casinos that accept Illinois residents. Our RTP calculator helps you choose games with the best odds regardless of where you play.
Which game has the highest RTP?
Blackjack with perfect basic strategy can reach 99.5% RTP or higher. Video poker (Jacks or Better) can exceed 99.5% with optimal play.

No, RTP is a long-term theoretical average. Short-term results can vary significantly due to variance.

🧮 How RTP Is Calculated
Expected Loss per Bet = Bet Amount × (House Edge / 100)
Expected Loss over N Rounds = Bet × (House Edge / 100) × N
Theoretical Return after N Rounds = Bet × N – Expected Loss
Example: Bet $10 on a slot with 96% RTP (4% house edge). Expected loss per bet = $0.40. Over 100 rounds, expected loss = $40, theoretical return = $960.
For games with strategy (blackjack, video poker), RTP assumes optimal play. Actual RTP may be lower if you make mistakes.
