General jackpot information

  • This game has a progressive jackpot.
  • The Jackpot prize is awarded randomly.
  • No symbol combinations are necessary for winning.
  • The probability of getting a jackpot is determined by the size of the bet.
  • The jackpot growth rate is 3% of game bets.
  • In addition, the house places a seed amount in the jackpot after every jackpot hit.
  • For this jackpot the seed amount is $4,500, or the equivalent amount in other play currencies offered.
  • This jackpot is shared with other games.
  • This jackpot is not capped in any way.

Consecutive jackpot wins

  • Imperfections of internet communications should not affect progressive jackpot fairness or potential jackpot wins.
  • In each progressive jackpot there is a seed amount, used for intro and refills.
  • In each progressive jackpot, there can be two sequential wins, separated by anything from seconds to months apart.
  • Let’s say a given jackpot starts growing based on contributions made during subsequent players’ rounds. Let's suppose the jackpot is now at 1500 USD. If two players win the jackpot seconds apart, the first will win the 1500 USD while the second will win the seed plus all the contributions accrued since the first jackpot drop.
  • The in-game and lobby jackpot counters are refreshed every ~15 seconds (depending on the type of internet connection available to the player) which is very fast, so most likely the second (consecutive) winner would be already aware that the jackpot has been reset prior to winning it.
  • The above is true for both real money and demo money jackpots and for both PC and mobile-based games.
