Psiky開發，並由City Connection移植至Nintendo Switch平台的《對戰脫衣麻將：角色扮演雀》（Hot Gimmick Cosplay-jong），是90年代末期街機市場中極具特色的「對戰麻將」系列作品。本作將傳統日本麻將的策略性與大膽誇張的視覺呈現結合，以「Cosplay」為核心主題，玩家將在麻將桌上遇見多位魅力十足的女性角色，並配合逗趣甚至帶有成人幽默的懲罰機制。在Nintendo Switch上，高解析度的畫面與便捷操作介面完整重現了這部異色街機經典。

故事背景設定於一場充滿惡作劇與奇思妙想的麻將競技大賽。主角在比賽中會面對各式各樣個性鮮明的女性角色，包括學生、女僕，甚至帶有科幻風格的戰士。雙方達成協議：若主角勝出，對方就必須換上指定的Cosplay服裝，或接受誇張搞笑的懲罰。雖然本作帶有成人娛樂元素，但誇張的角色反應與荒誕演出使整體氛圍輕鬆活潑，營造出既趣味又具娛樂性的遊戲體驗。

在操作與系統設計上，核心在於簡單直觀的麻將對戰。使用Joy-Con輕鬆進行捨牌、碰、槓、胡等動作，而最具特色的是進入「懲罰階段」時，必須在限定時間內快速連按按鍵。按鍵速度越快，畫面角色的Cosplay姿態與反應越豐富，將動作遊戲的物理反饋巧妙融入益智競技中，這也是該系列能在街機中脫穎而出的重要原因。

此外，還內建豐富的特殊道具與作弊系統，利用積分購買如「換牌」、「起手好牌」或「透視對手」等技能。Switch版本特別提升畫面解析度，並提供隨時存檔功能，降低長時間對局的門檻。還加入「連打自動化」選項，讓玩家可單純欣賞角色畫面與劇情，充分體現家用移植版的親民設計。

在市場評價方面，被視90年代日本街機次文化的代表作品。正面評價稱讚其誇張且具時代感的美術設計，以及極具爽快感的操作體驗，成功將單調的單人麻將轉化為具視覺張力的娛樂遊戲。彩京團隊一貫的高品質角色立繪與多變的Cosplay主題，使其在同類作品中保持領先地位。

雖然有評論指出遊戲策略深度主要體現在視覺呈現而非麻將本身，且成人內容較具針對性，但對喜愛懷舊街機與收集服裝美少女的玩家而言，本作仍具高度收藏價值。總結來說，《對戰脫衣麻將：角色扮演雀》不僅是一款麻將遊戲，更是一段90年代日本街機界大膽創意與幽默感的回憶。Switch移植版本讓現代玩家能重溫那段充滿「連打快感」與「變裝樂趣」的瘋狂歲月。

Developed by Psikyo and ported to the Nintendo Switch by City Connection, Hot Gimmick Cosplay-jong is a highly distinctive arcade title from the late 1990s “competitive mahjong” genre. The game merges traditional Japanese mahjong’s strategic intensity with bold visual presentation, centering on a “cosplay” theme. Players encounter a roster of charming female characters, each paired with humorous and sometimes risqué penalty mechanics. On the Switch, the high-resolution graphics and streamlined interface faithfully recreate this quirky arcade classic for modern audiences.

Set within a zany mahjong tournament filled with pranks and imagination, the story unfolds across a series of matches featuring women with varied personalities—from schoolgirls and maids to sci-fi-inspired warriors. Players must compete to win, with the agreement that losing opponents will change into specific cosplay outfits or undergo comical, exaggerated penalties. While the concept is adult-oriented, the over-the-top reactions and absurd presentation create a lighthearted, energetic atmosphere that emphasizes fun and spectacle over realism.

From a gameplay perspective, the core innovation lies in its fast-paced, intuitive mahjong mechanics. Players use the Joy-Con to select discards, call pon, kan, or declare ron, making gameplay accessible even for newcomers. A standout feature occurs during the “punishment phase,” where players must rapidly mash buttons within a time limit. The faster the input, the more varied and animated the character’s cosplay reactions become, blending the physical feedback of action games into a puzzle-oriented competitive match—a key factor that made the series stand out in arcades.

The game also includes a robust special items and “cheat” system, allowing players to purchase abilities such as tile swaps, advantageous starting hands, or the ability to glimpse opponents’ tiles. The Switch version further enhances graphics, adds save-anywhere functionality, and includes an optional auto-button-mash mode, letting players focus on enjoying the visual and comedic elements without physical strain. This adaptation demonstrates thoughtful consideration for home players who may not enjoy lengthy, demanding arcade sessions.

In terms of reception, Hot Gimmick Cosplay-jong has earned a unique place in gaming history as a symbol of 1990s Japanese arcade subculture. Critics praised its exaggerated, era-specific art design and highly satisfying gameplay loop, noting that it successfully transformed the traditionally solitary game of mahjong into a visually dynamic and entertaining experience. Psikyo’s high-quality character illustrations and varied cosplay themes helped the game maintain a standout status among similar titles.

While some criticism pointed out that strategic depth is secondary to visual spectacle, and that the adult-oriented content targets a niche audience, the game remains highly collectible for enthusiasts of retro arcades and costume-themed characters. Overall, Hot Gimmick Cosplay-jong is more than a mahjong game—it’s a nostalgic homage to the playful creativity of late-90s Japanese arcades. Its Switch port allows modern players to experience the chaotic joy of rapid button-mashing and cosplay antics that defined an unforgettable era.
