The "Jackpot Rounds" Goal requires you to play in any of the Bingo Stages that offer Jackpots (e.g., High Stakes, Midnight Express, Golden Cherry, etc.). You can find most of these Stages in the High Rollers Lobby.
For your Jackpot rounds to count towards this Goal, at least 1 Jackpot Card must be played. You can learn more about the Jackpot feature HERE.
To unlock the Jackpot feature, you must play a minimum of 4 Cards and increase your bet. Every 4 Cards played will unlock the higher Jackpots.
Below is an example of a Jackpot Card (Mini) unlocked which will be available when you start the Bingo round.
As long as the Mini Jackpot Card is in play, your rounds will count towards this Goal.
If all three Mini, Super, and Grand Jackpot Cards are grayed out, your rounds will NOT count.
