Understanding Cleopatra Keno

Cleopatra Keno is a popular Egyptian-themed variation of the classic Keno game that offers players a chance to win doubled payouts when the last ball drawn completes a winning pattern.

How Cleopatra Keno Works
  • Pick Your Numbers: Select 1-10 numbers (spots) from the 80 available
  • Ball Drawing: 20 numbers are randomly drawn from 80 possible numbers
  • Last Ball Bonus: If the 20th (last) ball drawn completes a winning combination, the payout is doubled
  • Payouts: Determined by how many of your selected spots match the drawn numbers, with increased pay for last ball wins
Last Ball Bonus Mathematics

The calculator uses combinatorial mathematics to determine:

  • Standard Win Probability: Chance of winning with the first 19 balls
  • Last Ball Win Probability: Chance of completing a winning pattern with specifically the 20th ball
  • Combined Expected Value: Considering both standard and last ball bonus payouts

The last ball feature adds approximately 10-15% to the overall return percentage compared to standard Keno.

Optimal Strategy Tips
  • The last ball bonus makes higher catch requirements more valuable than in standard Keno
  • Playing 7-9 spots typically offers the best balance of hit frequency and payout potential
  • Look for machines with higher payouts on mid-range hits (4 of 8, 5 of 9, etc.)
  • The Cleopatra last ball bonus significantly improves the overall return percentage compared to standard Keno

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.

Expected Value (EV) Formula:

EV = Σ [P(hit) × Payout(hit)] + Σ [P(last ball hit) × Payout(hit) × Last Ball Multiplier]
