How do plain-trick games differ from point-trick games?

In the context of trick games, the primary difference between plain-trick and point-trick games lies in the objective of the play.1

• Plain-trick games: The fundamental goal is to win as many tricks as possible, or in some variations, to win a specific number of tricks as determined by a bid (such as in bridge, whist, or spades).1
• Point-trick games: The objective is to capture specific cards within the tricks that hold point values, rather than simply maximizing the total number of tricks won. Examples of this category include skat, all fours, and tarot games.1

While both types involve players taking turns playing cards to the table to win tricks, the scoring criteria distinguish them: one focuses on the quantity of tricks secured, while the other focuses on the value of the cards contained within those tricks.1
