Every gambler knows the saying: “The House Always Wins.” But the House doesn’t win the same amount from every game. There is a massive mathematical difference between playing Blackjack with basic strategy and spinning a Penny Slot machine.
Our all-in-one Casino Games Odds Calculator is the ultimate aggregator tool. It allows you to instantly compare the House Edge and Expected Loss per Hour across the most popular casino games. Stop guessing where your bankroll is going—use the math to find the games that give you the best fighting chance.

How to Use the Casino Odds Calculator
This calculator functions as a simulator for your gambling session. By adjusting the variables, you can see exactly how “expensive” a game is to play over time.
- Select a Game: Choose from our database of presets, including Blackjack, Baccarat, Roulette (American vs. European), Craps, and Slots. The calculator will automatically fill in the standard House Edge and Game Speed (hands/spins per hour).
- Enter Your Average Bet: Input the amount you wager per round (e.g., $10).
- Set Session Duration: How long do you plan to play? (e.g., 2 hours).
- Analyze the Result: Look at the “Theoretically Expected Loss”. This number tells you how much the casino expects to earn from you on average during that session.
Examples: Why Game Selection Matters
Many players assume that betting $10 on Roulette is the same risk as betting $10 on Slots. The casino odds calculator proves this is false. Here is how different games impact your wallet:
Example 1: The “Smart” Player (Blackjack)
You play Blackjack with basic strategy (0.5% House Edge) for 2 hours, betting $10 per hand. The dealer deals about 70 hands per hour.
- Total Wagered: $1,400.
- Expected Loss: $7.00.
- Verdict: Very cheap entertainment. You have a high probability of booking a winning session.
Example 2: The “Fast” Player (Slots)
You play a High Limit Slot Machine (5% House Edge) for 2 hours, betting the same $10 per spin. However, slot machines are fast—you spin 500 times per hour.
- Total Wagered: $10,000.
- Expected Loss: $500.00.
- Verdict: Even though the bet size ($10) was the same as Blackjack, the combination of higher House Edge and extreme speed cost you 70 times more money.
Example 3: The Roulette Trap (0 vs 00)
You switch from European Roulette (Single Zero, 2.7% Edge) to American Roulette (Double Zero, 5.26% Edge). The calculator shows that this simple switch nearly doubles your hourly losses without increasing your potential payouts.
Frequently Asked Questions (FAQ)
Which casino game has the best odds?
Mathematically, Blackjack (played with perfect basic strategy) and Video Poker (specifically “Jacks or Better” or “Deuces Wild”) offer the best odds, often with a House Edge under 0.5%. The “Don’t Pass” line in Craps and the “Banker” bet in Baccarat are also excellent choices with an edge near 1%.
What is “House Edge”?
House Edge is the mathematical advantage the casino holds over the player, expressed as a percentage. If a game has a 5% House Edge, the casino expects to keep $5 for every $100 wagered over the long run. The lower the percentage, the better for the player.
Why does “Game Speed” matter in the calculator?
Speed kills bankrolls. A game with a low edge (like Baccarat) can still be expensive if played at a “Speed Baccarat” table dealing 100 hands per hour. Conversely, a game with a higher edge might be cheaper if the pace is slow (like a crowded Roulette table). Total Expected Loss = Edge × Bet Size × Speed × Time.
Are slot machine odds accurate?
Slot odds vary by casino and jurisdiction. Our calculator uses standard benchmarks: ~5% edge for High Limit ($1+) slots and ~10-15% edge for Penny Slots. In reality, Penny Slots often have the worst odds in the entire casino.
