Understanding RTP and House Edge
RTP (Return to Player) and house edge are fundamental concepts in casino game mathematics. Understanding these terms helps you make informed decisions about which games to play when wagering bonuses, ultimately affecting your chances of successfully completing wagering requirements. In 2025, with more transparency about game mathematics, players can make better-informed choices.
💡 Key Concept
RTP and house edge are two sides of the same coin. RTP is what you get back, house edge is what the casino keeps. Together they always equal 100%.
What is RTP (Return to Player)?
Definition
RTP is the percentage of all wagered money that a game will pay back to players over time:
- 96% RTP: For every $100 wagered, $96 is returned (on average)
- 97% RTP: For every $100 wagered, $97 is returned (on average)
- 98% RTP: For every $100 wagered, $98 is returned (on average)
How RTP Works
RTP is calculated over millions of spins/bets:
| RTP | House Edge | Expected Loss (per $1,000) | Best For |
|---|---|---|---|
| 98%+ | 2% or less | $20 or less | ✅ Excellent for wagering |
| 96-97.9% | 2-4% | $20-$40 | ✅ Good for wagering |
| 94-95.9% | 4-6% | $40-$60 | ⚠️ Acceptable |
| <94% | 6%+ | $60+ | ❌ Avoid for wagering |
What is House Edge?
Definition
House edge is the casino's mathematical advantage over players:
House Edge Formula
House Edge = 100% - RTP
Example: 96% RTP = 4% house edge
How House Edge Affects You
The house edge determines your expected loss:
- 4% house edge: Expect to lose $4 per $100 wagered
- 3% house edge: Expect to lose $3 per $100 wagered
- 2% house edge: Expect to lose $2 per $100 wagered
RTP by Game Type
Slots
Slot RTP varies significantly:
| Slot Type | Typical RTP | House Edge | Best For |
|---|---|---|---|
| High RTP Slots | 97-99% | 1-3% | ✅ Best for wagering |
| Standard Slots | 94-96% | 4-6% | ✅ Good for wagering |
| Low RTP Slots | 90-93% | 7-10% | ❌ Avoid for wagering |
| Progressive Slots | 92-94% | 6-8% | ❌ Usually excluded |
Table Games
Table games typically have better RTP but lower contribution:
- Blackjack: 99-99.5% RTP (with basic strategy)
- Baccarat: 98.94% RTP (banker bet)
- Roulette: 97.3% RTP (European), 94.74% (American)
- Craps: 98.64% RTP (pass line bet)
How RTP Affects Bonus Wagering
Expected Loss Calculation
Higher RTP means less expected loss during wagering:
Expected Loss Comparison
Expected Loss = Total Wagering × House Edge
| Wagering: | $6,000 |
| 97% RTP (3% edge): | $180 expected loss |
| 96% RTP (4% edge): | $240 expected loss |
| 95% RTP (5% edge): | $300 expected loss |
Finding RTP Information
Where to Look
RTP is usually found in:
- Game Information/Paytable: Most common location
- Game Rules: Often listed in help section
- Casino Website: Some casinos list RTP on game pages
- Third-Party Sites: Game review sites often list RTP
Using RTP for Bonus Strategy
Strategy 1: Prioritize High RTP Games
When wagering bonuses, choose games with highest RTP:
- Minimizes expected loss
- Preserves bankroll better
- Increases completion probability
- Maximizes bonus value
Strategy 2: Avoid Low RTP Games
Games with RTP below 94% should be avoided:
- Higher expected loss
- Reduces bonus value
- Makes completion harder
- Wastes bankroll
⚠️ Important Note
RTP is a long-term average. Short-term results can vary significantly. However, choosing higher RTP games still gives you the best mathematical advantage.
