How long is the game Alice is missing?

Excuse me, but could you please clarify something for me? I'm a bit confused about the phrase "How long is the game Alice is missing?" Are you referring to a specific game that Alice has gone missing from, or is this a metaphorical question about how long Alice has been absent from some activity or event? If it's the former, could you provide more context about the game and Alice's involvement? And if it's the latter, could you elaborate on what Alice is missing and why you're asking about the duration of her absence? Thank you for your clarification.
