Another piece from kotetsu who has been an amazing go-to for this series, churning these out like it's nothing!
For this event challenge: Win a jackpot that someone else left one or more credits in. (You may swipe one credit so that the tickets go to your card, however the jackpot must be won on one of the credits that was in the machine before, NOT the credit you swipe in. For example, if someone left 1 swipe in Kung-Fu Panda, and you swipe once, winning on the first game counts, winning on the second game does not.) I will take you at your word on this challenge.
This challenge is a very easy one by design; it reminds players the importance of being aware of their surroundings, looking to see if machines have had players foolishly leave a game or games on them. That's free money if you know what you're looking for!
