Players choose from a collection of cards, tiles or other game components. This can be closed drafting, taking cards etc from your hand and passing the rest or from a common face up pool.
Players attempt to collect sets of either matching or different items in order to score points. Typically the more items in the set the more points. Sets are usually groups of cards but could tokens or items as well.
Players place workers to take actions or collect cards and resources. Workers can be player pieces or sometimes dice or other components granting variability or powers to that worker/action.
