How to Use the Keno Odds Calculator on Chipy

You don't have to be a math genius to find the odds for Keno. All you need are a few minutes.

Step 1: Set Your Game Parameters

Tell the calculator how many balls are drawn. Most Keno games draw 20 balls from 80 (which is the default setting on our calculator), but I've seen 10 from 70 and 25 from 90. 

Check your casino's rules and enter the exact numbers.

Step 2: Select How Many Keno Picks You Want

How many picks are you playing? From my experience, it’s usually 1 to 15.

Most people think that more numbers equal better odds. They're wrong. The math doesn't work that way. We'll get to that in a minute.

For now, just select your number of picks. You can change it and recalculate in five seconds.

Step 3: Advanced Settings (Don't Skip This)

I'm guessing you haven't got around to this part yet. Big mistake.

Click "Advanced Settings." Enter your bet amount and the casino's paytable. This means typing in how much they pay for each matched number.

Hit 5 out of 5 and win 800x? Enter 800 next to 5. Hit 3 out of 5 and win 2x? Enter 2 next to 3. Some matches pay nothing. Enter 0 for those.

Also, add your bet amount. Playing $10 per game? Enter 10.

Calculate again.

Now you can see the expected return. This is your reality check. If it says 0.65, you're getting back 65 cents per dollar over time. The house keeps 35 cents.

This number tells you whether you're at a good casino or getting fleeced.

Step 4: Hit Calculate

Click the green button. Done.

The results table will show everything:

• Number of matches
• Prize (if you entered your bet amount)
• Total combinations for each match level
• Your actual odds of hitting each level
• The expected return (a.k.a. what this means for your wallet)

Why Our Keno Odds Calculator is a Game-Changer

It’s simple: most casinos aren’t telling you the whole truth.

Suppose there are two casinos on the same street. Both are running standard Keno. You want to play 7 spots at $10.

Casino A pays:

• 7/7: 5,000x
• 6/7: 100x
• 5/7: 15x
• 4/7: 2x

Casino B pays:

• 7/7: 7,500x
• 6/7: 75x
• 5/7: 10x
• 4/7: 1x

Which is better?

Most people say Casino B. That 7,500x jackpot looks amazing.

Wrong.

Run both through this calculator. Casino A gives you better expected returns. Why? Because you'll hit 5 or 6 numbers way more often than all 7. Casino A pays more on the hits that actually happen.

Casino B dangles a shiny jackpot and shorts you everywhere else.

Over 100 games, you'd lose $200 less at Casino A. That's the price of not knowing the math.

Here are some other reasons:

You Can Test Keno Strategies Risk-Free

Should you play 3 spots or 10? What's going to be easier for you to win with?

Test your Keno strategy here. Free. Fast. Before you spend a cent.

I watched someone play 10-spot Keno for three hours last month. They hit a few matching numbers every game but still lost $800. They came back the next day and did it again.

What do you know? They never once calculated their expected return. It was 0.58. They were losing 42% of every bet to the house edge.

Don't be that person.

The "Hot Numbers" Myth Dies Here

People track which lucky numbers hit, then bet those same numbers because they're "hot."

Here's the truth: Keno machines don't have memory. Every number has identical odds every single game.

This calculator proves it. Pick any 5 numbers. Calculate. Now pick 5 completely different numbers. Calculate again.

Same odds.

Tracking hot numbers wastes your time. Use our Keno odds calculator to find the optimal number of picks instead.

Understanding Expected Returns (In Plain English)

You'll average expected return per dollar bet over thousands of games.

Higher expected returns are better. 0.75 beats 0.65. You're losing slower.

From our experience, two types of people ignore expected returns. The first one doesn't know it exists because he never read the Keno rules. The second type knows but plays anyway.

If you're reading this, you're neither. You're taking the time to learn the math before you play. That puts you ahead of 90% of Keno players.
