How is skat classified among trick-taking card games?

In the classification of trick card games, skat is categorized as a point-trick game.1

In point-trick games, the primary objective is to win the greatest value of point-scoring cards contained within the tricks, rather than simply winning the highest number of tricks. This distinguishes it from plain-trick games, where the goal is to win as many tricks as possible or a specific number of tricks, and from trick-avoidance games, where the goal is to avoid winning certain cards or tricks entirely.1
