This game starts with a random bunch of marshmallows. A spicy hot pepper is put into one marshmallow. Two players then alternate turns choosing and eating 1, 2, or 3 marshmallows. The marshmallow with the pepper can easily be seen and avoided... until a player is stuck on their turn with only the spicy marshmallow left to choose and eat. https://www.youtube.com/watch?v=-ZAVZ9-Iu_Q Here, you'll be competing against a random spinner. As soon as a game ends, the next will start.
