I just won a game of Bluff, and it said I won 10k sp and 3 carnival tickets. What are carnival tickets?

carnival tickets can be spent in the carnival prize shop (the tent with the sign with a picture of a ticket on it). it used to be, you had a random chance of getting one of those items every time you won, but now it's been changed so you can save your tickets and spend them on whatever you want.

Thank you!
