"猜字谜游戏" can be translated into English as "word guessing game" or "charade game (focused on guessing characters/words)".
"Word guessing game" is a straightforward and commonly used phrase that directly conveys the idea of guessing words.
"Charade game" originally refers to a game where players act out words or phrases, but in some contexts, it can also be adapted to describe games involving guessing characters or words, especially when there's an element of performance or hint-giving involved. However, for a more precise match to "猜字谜游戏" (which typically involves solving riddles or puzzles to guess a character or word), "word guessing game" is more appropriate.
For a more specific and culturally relevant translation, especially if referring to the traditional Chinese "猜字谜" (cāi zì mí), which involves solving riddles to guess a Chinese character, you might also encounter translations like "Chinese character riddle game" or simply "character riddle game" in specialized contexts. But in general usage, "word guessing game" is a suitable and widely understood translation.
