《節奏天國》（日文原名：リズム天国，英文常譯為Rhythm Tengoku）是由任天堂與知名開發團隊Nintendo SPD（後來整合進入任天堂企劃開發本部）合作開發的音樂節奏類遊戲，最初於Game Boy Advance平台推出，其後又以更豐富的內容和進化的操作系統登上Wii平台，該版本正式名稱為《リズム天国 ゴールド》（國際版本常簡稱為《Rhythm Heaven Fever》）。在2011年於日本發售，2012年於北美與歐洲推出，是節奏天國系列第三作，延續系列一貫的極簡畫風與「節奏反應」為核心的玩法設計。

劇情方面，與多數任天堂經典風格類似，並沒有明確的主線劇情，也不以角色塑造或敘事驅動遊戲，而是藉由一系列風格迥異、創意十足的迷你遊戲串連成節奏世界。每個關卡都是獨立的小故事、小情境，從忍者修練、猴子鼓掌、機器人裝配到唱片搖擺、韻律棒球，每關都有自己的節奏主題、風格與音樂，透過動作與節拍的精準配合來挑戰玩家的反應與聽覺記憶。儘管沒有傳統劇情，但整體遊戲設計充滿幽默與戲劇性，在關卡過程中會不自覺地被這些天馬行空的設定與誇張演出逗笑，進而進入一種節奏感驅動的「沉浸式」體驗。

操作方面，採用極其簡化的操作方式，只需使用一個按鈕（通常是A鍵，部分關卡需用A+B鍵）來配合音樂節奏進行互動。這種「極簡但精密」的設計哲學讓遊戲門檻極低，任何年齡層的玩家都可以輕鬆上手，但若要達到「完美演出」則需要極高的節奏敏銳度與記憶力。遊戲的精髓不在於畫面反應，而是「用耳朵玩」，必須緊貼音樂節奏，甚至在畫面變化不大時也要依靠節奏判斷時機。每一組關卡包含四個主遊戲與一個「混合節奏關卡」，將前面幾關的玩法組合成一個連貫挑戰，考驗玩家對各種節奏模式的掌握與切換能力。

Wii版的視覺表現延續系列的手繪風格與誇張動畫，簡約但不簡單，每一關都有獨特的角色設計與舞台色調。例如有的關卡呈現舞台劇風格，有的則是3D剪影動畫，亦有不少明顯受到日本漫畫與昭和動畫啟發的視覺呈現。整體風格讓人感受到「任天堂式的實驗性幽默」，與主流音樂節奏遊戲強調炫目特效的路線完全不同。配樂方面，原創音樂極為多樣，涵蓋電子、搖滾、放克、流行甚至民謠風，每首樂曲都經過精心設計，並與遊戲互動設計密不可分。

在市場評價方面，獲得日本與國際玩家的一致好評。日本《Fami通》給予本作高分34/40，稱讚其玩法創新、幽默感十足且極具黏著力。玩家普遍表示本作讓人「邊笑邊玩」，是既放鬆又具有挑戰性的作品。在歐美市場，IGN給出8.5分，讚揚其簡潔操作與出色配樂，認為它是音樂遊戲中最獨特的一支；GameSpot則表示「這是一場節奏與幽默的完美融合」，唯一的批評是關卡數量稍顯有限，若已達成全部完美等級後可能缺乏後續挑戰，但整體體驗仍十分優秀。

總結來說，這是極具任天堂特色的節奏遊戲傑作，以幽默、創意與精準節奏感三者巧妙融合，創造出一個只屬於它自己的遊戲節奏世界。並不依賴華麗畫面或複雜系統，而是回歸「音樂與節奏」的本質，透過簡單操作傳遞純粹的遊戲樂趣。對於熱愛節奏遊戲或想找適合家庭同樂、隨時可以上手的小品佳作的玩家而言，這是不容錯過的代表性作品。

Rhythm Tengoku (Japanese title: リズム天国, commonly translated as Rhythm Heaven or Rhythm Heaven Fever in international versions) is a music rhythm game developed by Nintendo in collaboration with the renowned development team Nintendo SPD (later integrated into Nintendo EPD). The game originally debuted on the Game Boy Advance, but the version released for the Wii platform features expanded content and refined controls. This Wii edition, titled Rhythm Tengoku in Japan, was released in 2011 and later launched in North America and Europe in 2012 under the title Rhythm Heaven Fever. It is the third main installment in the Rhythm Tengoku series, continuing the franchise’s tradition of minimalist visuals and gameplay focused entirely on rhythm-based interaction.

Unlike traditional narrative-driven games, Rhythm Heaven Fever does not feature a conventional storyline. Much like other classic Nintendo titles, the game forgoes deep character development or linear plots in favor of a unique and playful world built around rhythm. Each level is essentially a standalone mini-game, presenting its own quirky scenario and rhythm challenge. Players may find themselves training as ninjas, clapping with monkeys, assembling robots, swinging records, or hitting rhythm baseballs—each with a distinct musical style and tempo. Although there's no overarching narrative, the whimsical animations and unexpected gameplay twists create a sense of storytelling through rhythm and visual comedy, leading players into an immersive and often laugh-out-loud experience driven entirely by sound and timing.

The gameplay is built on a philosophy of “simple yet precise” interaction. Players typically only need to use one button (the A button, and occasionally A + B) to interact with the beat. This minimalistic control scheme makes the game extremely accessible for players of all ages, yet achieving a “Perfect” performance requires sharp timing, a fine sense of rhythm, and auditory memory. Crucially, Rhythm Heaven Fever is a game played more with the ears than the eyes—visual cues are minimal, and many challenges depend on listening closely to the music to determine the exact timing for action. Each stage set usually includes four core rhythm games and one "Remix" stage, where all previous rhythms are blended into a single, continuous sequence that tests the player’s adaptability and musical intuition.

Visually, the Wii version stays true to the series’ hand-drawn, exaggerated aesthetic. Each stage has its own unique character designs and visual themes, ranging from theater-style performances to 3D silhouettes and segments clearly inspired by classic manga and Showa-era animation. The result is a look and feel that embodies Nintendo's experimental humor, diverging sharply from the flashy, special effects-heavy style typical of Western rhythm games. The game’s soundtrack is equally diverse and memorable, encompassing genres like electronic, rock, funk, pop, and even folk. Each track is intricately woven into the gameplay design, ensuring that music and mechanics are inseparable.

In terms of critical reception, Rhythm Heaven Fever was met with widespread acclaim both in Japan and internationally. The Japanese publication Famitsu awarded it a high score of 34/40, praising its innovative gameplay, quirky humor, and addictive charm. Players often described it as a game that makes you “laugh while you play,” balancing relaxation with challenge. In the West, IGN gave the game an 8.5 out of 10, lauding its elegant simplicity and outstanding music, and calling it “one of the most unique entries in the music game genre.” GameSpot echoed this sentiment, calling it “a perfect blend of rhythm and humor.” The main criticism was the relatively small number of stages, which meant that players who achieved “Perfect” ratings on all levels might find themselves wishing for more content. Still, the overall experience remained compelling and memorable.

In conclusion, Rhythm Heaven Fever is a shining example of Nintendo’s signature creativity and design excellence. It doesn’t rely on high-end graphics or complex systems, but instead returns to the core of rhythm gaming—pure musical timing, fun, and imagination. Its perfect blend of humor, style, and gameplay creates a world where rhythm is everything, and where joy is found in the simplest of taps. For rhythm game enthusiasts, families, or anyone looking for a lighthearted and instantly accessible experience, this title stands as a must-play classic of the Wii era.
