Kristoffer guesses least accurately
Here's a description of the contestant's attempt. Someone's probably working on collecting some images to illustrate it.
In the first round, Kristoffer wrote the word 'poop'. In the second round, he wrote 'fork'. In the third round, he wrote 'masturbating'. In the final, he guesses that Olli has 5 jellymen in his pocket, and so is eliminated for being the furthest out.
