About this game

Someone actually knows the answer, while others can only improvise!

9UPPER Online is a free multiplayer social deduction party game for 3 to 9 friends. Create an online room, share the room code, and everyone can join using their own mobile phone—no account registration required.

Only one player sees the real answer each round. The others must improvise a plausible explanation, then discuss, observe, and vote to find the person who truly knows the answer. The person in the know must convince the entire room, while the others must use their eloquence and reasoning to confuse the others.

Features:
・Playable with 3 to 9 players
・Hong Kong Traditional Chinese, Taiwan Traditional Chinese, and English interface and question bank
・Original trivia questions
・Playable in person or remotely via voice call
