To win a jackpot you must make a spin with the appropriate qualifying bet. Each time a player attempts to win, a portion of the bet is added to the jackpot total. You do not have to land on any specific combination of the reels to trigger the feature.
Each qualifying bet gives you the opportunity to win the Jackpot. A portion of your bet is contributed to the total Jackpot Fund. Jackpots cannot be won during free spins. Once the free spins are over, your bets will continue to qualify for the jackpot. Jackpots can vary from game to game and are displayed over available machines in the main game lobby so you can see if there is currently a jackpot in your favorite game.
