There are three animals and three decorations to win here. Here's a list of what you can win:
Green Farm House
Luckily, even with the inclusion of a unicorn (which is a highly sought after species of animal in the game), this week's Mystery Game only costs the standard 16 Farm Cash for a single dart to throw at the board. Of course, you're not guaranteed the Shamrock Unicorn when you play the game, but at least you won't lose more than the minimum Farm Cash in your attempt.
As usual, this Mystery Game set will only be available for the next week, at which point the available prizes will be swapped out for new items.
