Cutdle asks you to split the shape on screen with a single straight line. The goal is to make the two halves as equal as possible. You get 30 seconds and exactly one attempt; the moment you release, the result opens and shows how close you got as a percentage.
Once everyone has cut, players are ranked by how close they landed to 50/50. First takes +3, second +2, third +1. So a round always produces a winner even when nobody cuts it perfectly.
