《比利在哪裡？》（Where is Billy?）是以「策略型多人躲貓貓」為核心概念的派對遊戲，近日正式登陸 Nintendo Switch平台。以獨特的「比利鬼屋」為舞台，將玩家帶入充滿惡作劇氛圍與驚悚又搞笑的捉迷藏比賽。這是怪物們的狂歡之夜，主人設計一個離奇的挑戰：所有受邀的怪物嘉賓都必須在這片人潮湧動的「怪物海」中隱匿身份，需要在混亂之中找到自己的定位，或巧妙地偽裝以避免被識破。

劇情設定上，雖然不以敘事為主，但仍構建一個別具氛圍的背景。比利鬼屋在萬聖夜般的夜晚開啟，奇形怪狀的賓客齊聚一堂。進入遊戲後，並不知道自己扮演的是哪一個角色，唯一的生存之道就是在重重「怪物人群」之中隱藏自己，同時運用觀察力與推理，逐步找出對手的行動模式。這種設定讓人身處在一種「既陌生又熟悉」的局面裡，增添緊張感與趣味性。

操作方面，支持2至8名玩家，可以選擇線上連線或本地多人同樂。玩法的核心是「人群偽裝」與「找尋真相」：每位玩家的角色都會隱藏在大批NPC當中，大家的動作與行為都極為相似。若想獲勝，需要保持冷靜，避免做出過於突兀的舉動，同時觀察細節，找出人群中「不合群」的對象。這使得比賽既是心理博弈，又考驗操作的細膩度。此外，內建中文介面與語言支持，能更輕鬆投入遊戲氛圍，無論是與朋友聚會還是在線上隨機對戰，都能快速進入狀況。

在市場評價方面，作品的定位被視為派對遊戲領域的新嘗試。融合「狼人殺」式的心態博弈與「Among Us」般的隱藏推理元素，但呈現方式更輕鬆搞笑，也更適合快速開局、短時間內連玩多回合。玩家社群普遍認為，這款遊戲非常適合朋友聚會，尤其在同一個房間裡本地對戰時，氣氛常常因「誤判」或「裝傻」而引發笑聲。部分媒體則指出，遊戲的耐玩度取決於玩家群體的活躍程度，如果缺少互動性強的朋友群，整體體驗可能會略顯單調。不過整體來說，《比利在哪裡？》憑藉其獨特的設定、簡單的操作與策略深度，已經成功吸引不少派對遊戲愛好者，特別是在喜歡多人互動和「惡作劇式」娛樂的玩家群體中，展現不錯的潛力。

Where is Billy? is a party game built around the core concept of “strategic multiplayer hide-and-seek,” and it has recently launched on the Nintendo Switch platform. Set against the unique backdrop of “Billy’s Haunted House,” the game draws players into a prank-filled, eerie yet humorous hide-and-seek competition. On this raucous monster’s night, the host has prepared a bizarre challenge: all invited monster guests must conceal their identities within a teeming crowd of creatures, forcing players to either locate themselves amidst the chaos or cleverly disguise their actions to avoid detection.

In terms of story setting, while the game does not emphasize a narrative, it nevertheless establishes a distinctive and atmospheric backdrop. Billy’s Haunted House opens on a night reminiscent of Halloween, with a hall full of bizarre guests. Upon entering the game, players have no idea which character they are playing as—the only way to survive is to blend into the throng of “monster crowds,” relying on keen observation and deduction to gradually uncover opponents’ behavioral patterns. This design places players in a space that feels both “strange and familiar,” heightening the sense of tension and amusement.

From a gameplay perspective, Where is Billy? supports 2 to 8 players, with both online matchmaking and local multiplayer modes available. The core mechanics revolve around “blending in with the crowd” and “finding the truth”: each player’s character is hidden among numerous NPCs, all of whom behave in very similar ways. To win, players must stay calm, avoid conspicuous actions, and carefully observe details to identify the “out of place” individuals within the crowd. This creates a contest that is both psychological mind game and a test of precise execution. The game also comes with built-in Chinese language support, making it easy to immerse oneself in the atmosphere—whether playing casually with friends at a gathering or joining random matches online.

In terms of market reception, the game is regarded as a fresh experiment in the party game genre. It blends the psychological bluffing of Werewolf with the hidden-role deduction of Among Us, but presents them in a more lighthearted and comedic way, making it well-suited for quick matches or back-to-back rounds in a short play session. The player community largely views it as an excellent party game, especially fun during local multiplayer in the same room, where misjudgments or feigned innocence often spark bursts of laughter. Some media, however, have noted that its replay value depends heavily on having an active group of players—without an engaged social circle, the experience may feel somewhat repetitive. Nevertheless, Where is Billy?, with its unique premise, accessible mechanics, and underlying strategic depth, has already managed to attract a notable following of party game enthusiasts, particularly among players who enjoy multiplayer interaction and prank-style entertainment.
