There are three kind of lotteries in the Festival Plaza: Big Dreams, Gold Rush and Treasure Hunt. You can play those lotteries only once a day, and you will draw a number between 1 and 10, each number representing one of the 10 prizes of the lottery. It seems like they are pulling a random number everyday, but I'm getting the 10th one (Berry Juice) nearly everyday. I am guessing that the better rewards are less common, but I wonder if there is a special system behind that.
How does the Lottery system work in the Festival Plaza and what are the odds to get each one of the items?
