Four-handed game refers to a game that's played with four players. However, there are a variety of synonyms that can be used to describe this type of game. One option is to use the term "quadruple game," which emphasizes the role of the four players. Another way to describe a four-handed game is to call it a "four-player game," which is more straightforward but still gets the point across. Some other synonyms for four-handed games include "team game" (if players are divided into groups), "multiplayer game," and "quartet game" (if the four players are considered a musical quartet). Regardless of the term used, the important thing is that all four players are engaged and working together.
