Why do some casinos seem to “always win”? The answer usually comes down to casino win rate—how much the house keeps after wagers are placed. If you play or manage games, understanding this metric helps you make smarter decisions.
What Is Casino Win Rate?
Casino win rate is the percentage of money a casino retains from the total amount wagered over time. It tells you, “Out of all the action, how much did the property actually keep?”
Key definitions
- Win (or Revenue): Amount the casino keeps after paying players.
- Handle (slots) / Drop (tables): Total coin-in for slots; chips bought-in for table games.
- Hold % (Win Rate): Win ÷ Handle (slots) or Win ÷ Drop (tables), expressed as a percentage.
At a glance
- Slots win rate is often called “slot hold.”
- Table-game hold uses chip drop rather than all money wagered repeatedly.
- Daily swings can be large; long-term figures are more reliable.
Casino Win Rate vs. House Edge
The house edge is the built-in mathematical advantage of a game’s rules over an infinite number of trials. Casino win rate is the observed percentage a property actually keeps in a given period.
In short: house edge is theoretical; win rate is operational and influenced by luck, pace of play, buy-in behavior, bet sizes, and player skill.
How to Calculate Casino Win Rate (Step-by-Step)
- Choose the game type: Slots or table games.
- Gather totals: Win and Handle for slots; Win and Drop for tables.
- Apply the formula: Win Rate = (Win ÷ Handle/Drop) × 100.
- Use a long window: Monthly or quarterly averages smooth out variance.
Example: Slots
A penny slot bank shows $10,000 coin-in (Handle) and $800 Win for the day.
Win Rate = 800 ÷ 10,000 × 100 = 8%.
Example: Blackjack Table
Over a weekend, the drop is $5,000 and the casino wins $900.
Win Rate = 900 ÷ 5,000 × 100 = 18%.
Note: Table hold % often appears higher than a game’s advantage because “drop” measures buy-ins, not the total amount re-wagered repeatedly during the session.
Linking Win Rate to Player Expected Value
To estimate player expected value, multiply average bet by bets per hour and the game’s advantage, then by hours played. This shows the typical long-run outcome.
Quick EV walkthrough
Imagine $5 average bet × 60 spins/hour × 0.06 advantage × 3 hours = $54 expected loss. Real sessions vary, but over time this aligns with the math.
Real-Life Case Study: A Slot Floor Tweak That Paid Off
A mid-sized Midwest casino audited its penny-slot bank and found a consistent 7.5% hold with low coin-in during weekdays. Players weren’t engaging with the titles or denominations.
The operations team swapped two underperforming themes for popular multi-denom games and improved signage. Over the next quarter, coin-in rose 22%, while hold nudged to 8.1%. Net win increased meaningfully without making the games “tighter.”
- Takeaway for operators: Mix, denomination, and placement can lift performance even if hold changes only slightly.
- Takeaway for players: Popular banks may reflect higher engagement and time-on-device, not necessarily higher difficulty.
Typical Win Rate Ranges by Game
These are broad, illustrative ranges. Actual figures vary by jurisdiction, rules, and floor strategy.
- Slots: 5–12% hold on coin-in, with penny and themed titles often at the higher end.
- Blackjack: The casino’s built-in advantage can be near 0.5–2% depending on rules and player skill, while table hold % vs. drop can average in the teens.
- American Roulette (00): Advantage around 5.26%; observed table hold fluctuates widely by buy-in behavior.
- Craps: Pass line advantage about 1.41%; overall table hold depends on mix of bets and pace of play.
- Baccarat: Banker bet advantage near 1.06%; table hold often in the low-to-high teens vs. drop.
For the most accurate perspective, compare your property’s monthly and annual reports to regional averages published by gaming regulators.
Why Casino Win Rate Matters to Operators
For management, this metric drives planning, forecasting, and staffing. It also feeds into broader revenue metrics used to optimize the floor.
Operational levers
- Game mix and denomination strategy
- Floor layout and signage
- Rules and side bets for tables
- Marketing and player development
Core numbers to watch
- Win per unit per day (WPUPD)
- Time-on-device and occupancy
- Theo vs. actual results
- Hold trends by zone and shift
Smart Ways Players Can Use Win Rate
You can’t change the rules, but you can manage your risk and enjoyment. Here’s how to play with purpose.
- Choose favorable rules: For blackjack, prefer tables with better payouts and fewer restrictive rules.
- Manage pace: Slower play reduces hourly exposure to the game’s advantage.
- Set session budgets: Decide your stop-loss and stop-win before you start.
- Leverage loyalty: Earn comps that offset entertainment costs.
If you’re estimating player expected value, focus on average bet, pace, and session length—those levers are in your control.
Common Misconceptions About Win Rate
- “High hold means a tight scam.” Not always. Table hold vs. drop can look high even when the rules are player-friendly.
- “Short-term runs prove a game’s setting.” Variance can dominate daily results. Monthly data is more reliable.
- “All penny slots are the same.” Themes, math models, and denominations can change volatility and average returns.
Compliance, Fairness, and Responsible Play
Licensed casinos operate under strict regulations, independent testing, and reporting. If you’re concerned about fairness, check your state regulator’s monthly reports.
Gambling should be fun entertainment. Set limits, take breaks, and seek help if you feel it’s no longer recreational. In the U.S., call or text 1-800-GAMBLER for confidential support.

What are typical win rates for slots and tables?
Slots often range 5–12% of coin-in, while table hold vs. drop can average in the low-to-high teens. Actual numbers vary with rules, denominations, and player mix.
Can skill reduce my losses?
Yes, in skill-influenced games like blackjack and certain poker formats, better strategy narrows the built-in advantage. It doesn’t remove variance, but it improves long-run outcomes.
