Have a FFXIII save for the increased odds. Only use the machine with the 'summer's day' conditions. Start with around 16,000 coins. Leave it on overnight. --- Official Sabin and Layle of the Dissidia 012: Duodecim Final Fantasy Board.
Funny, I've been playing the slots for the past few hours with 5k coins over and over again, and only just now I won and got 15k coins but still no fragment, then when I found out it was called lucky coin, I realized I already got it from the first time I played the slots... Good luck, check your invent, maybe you already got it and didn't notice. --- Nier is best gaming I've had since KH and FFX. One that breaks my heart yet keeps it warm and hopeful and happy. We definitely need more games like this.
