There are Long-term and Spontaneous problems. While teams may prepare for the presentation of their solution to one of the Long-term problems over months until the competition, they encounter the Spontaneous problems only on-site and have to solve it within a few minutes. However, they may practice to solve Spontaneous in general, which often involves a ton of fun already. The third scoring category: Style, is presented together with the solution of the Long-term problem.
For the Long-term problem solution, a team may receive up to 200 points, for Spontaneous up to 100 points and for the Style presentation up to 50 points. Altogether, 350 points are possible.
