Caveman Keno Plus

Caveman Keno Plus is similar to standard keno, but with the addition of multipliers and extra balls. Of course, this comes at a cost: a lower starting pay scale.
Rules of Caveman Keno Plus

• The player places a wager and selects two to ten numbers from one to eighty.
• When the player is finished, the game chooses three numbers at random and marks them with eggs.
• The game will then select 20 numbers at random from 1 to 80.
• The player's introductory price will be determined by how many of the game's balls match the player's selections.
• If the game selects a number that includes an egg, the egg will hatch.
• Any win will be multiplied by four if exactly two eggs hatch. Any win will be multiplied by 8 if all three eggs hatch.
• If at least two eggs hatch AND the player already has a winning card based on the paytable, the game will draw three additional balls, which could result in a higher base payout if any of the three balls match any of the player's specified numbers.
• The multiplier will increase from 4 to 8 if the player wins the extra three balls with two eggs and one of the different balls matches the third egg.
• The sum of the primary reward and the multiplier will determine the final award.
