Understanding Caveman Keno

Caveman Keno is a popular variation of traditional Keno where players can select "egg" numbers from their chosen spots for additional multiplier potential.

How Caveman Keno Works

Pick Your Numbers: Select 1-10 numbers (spots) from the 80 available
Choose Egg Spots: From your selected numbers, pick 1-3 to be "eggs"
Multipliers: If your eggs are drawn, they multiply your winnings:
- 1 egg hit: 2x multiplier
- 2 eggs hit: 4x multiplier
- 3 eggs hit: 10x multiplier
Drawing: 20 numbers are randomly drawn from 80 possible numbers
Payouts: Determined by how many of your selected spots match the drawn numbers, plus any egg multipliers

Keno Mathematics

The calculator uses probability theory and combinatorial mathematics to determine:

Expected Value: The average return per dollar wagered
Hit Frequency: The probability of winning any prize
Variance: A measure of the volatility or risk of the game

All calculations are based on the standard 1-in-4 odds of any single number being drawn (20 numbers drawn from 80).

Optimal Strategy Tips

Playing more spots generally increases volatility
Eggs increase both potential rewards and variance
Most Caveman Keno machines offer the best returns on 7-9 spot games
The "catch" required for a win increases with the number of spots played

Disclaimer: This calculator provides theoretical results based on standard Keno probabilities and the specified paytable. Actual results may vary due to the random nature of the game. Different casinos and machines may offer different paytables. Always gamble responsibly.

Understanding the Caveman Keno Calculator

Odds simulation and expected value formula

The Caveman Keno Calculator simulates the odds based on your input settings such as number of spots (numbers you pick), number of eggs (bonus multipliers), wager amount, and number of games. It then performs a deep odds breakdown to show how often you'll win, how much you can expect to earn per game, and your probability of hitting egg multipliers.

Expected Value (EV) Formula:

EV = ∑ (Probability of Outcome × Payout for Outcome)

Example: If hitting 5 out of 8 numbers pays $10 and has a 1.2% chance, then:

EV (for that hit) = 0.012 × $10 = $0.12
