イカサマライフゲイム (Ikasama Life Game) is a VOCALOID song by producer kemu featuring GUMI on vocals. Uploaded to niconico on February 10, 2012, it was kemu's third VOCALOID release and rapidly gained traction, reaching VOCALOID Hall of Fame (殿堂入り) the same day, surpassing one million views by June 2012, and eventually crossing three million by February 2017. The title translates to "Rigged Life Game," and the lyrics paint a bleak narrative of a protagonist receiving cryptic, inescapable future predictions, warnings about rain and bus accidents, delivered by mocking "Jokers" in a stacked deck, framing life itself as a rigged card game. Although kemu is the sole credited artist, the track was a collaborative production: kemu handled composition, arrangement, and lyrics; GUMI provided the vocals; ハツ子 created the illustrations; ke-sanβ produced the video; and スズム served as sound coordinator. The song later appeared on the compilation album EXIT TUNES PRESENTS Vocaloconnection feat. 初音ミク (2012). In maimai, イカサマライフゲイム was added to the initial lineup of maimai でらっくす on July 19, 2019, under the niconico & VOCALOID genre. Its MASTER chart, designed by すきやき奉行, carries a level of 12+ (difficulty constant 12.9) and features dense Tap runs and rapid Slide sequences that match the track's frantic 200 BPM tempo. The EXPERT chart was designed by 華火職人. Players who clear the MASTER chart with rank S unlock the title "少年は平穏に暮らしたかった" ("The boy wanted to live peacefully"), a line taken directly from the original niconico video description. The song also appears in SEGA's other rhythm games, CHUNITHM (since 2015) and オンゲキ (since 2020), making it one of kemu's most widely circulated VOCALOID works across the SEGA arcade ecosystem.
