The win is the third that we've recorded since 2009 for this slot, but it has become the third hit that has occurred this year. As of right now, we don't know why this jackpot is being triggered so often. The largest of the three wins occurred in March when a player hit the prize for $4,420,568.
The jackpot is tied to this game specifically and grows with each spin of the reels. It pays off when the game sees five Aztec's Millions symbols splayed out on the game's five reels. The prize can be won with any bet amount and is awarded randomly.
We're awaiting details and will be updating readers as we learn more.
