Kine is a 3D puzzle game developed by Gwen Frey, released in 2019 for PC, PlayStation 4, Xbox One, Nintendo Switch, and Google Stadia. The game follows three mechanical characters — Euler, Quat, and Roo — each harboring ambitions of musical stardom. Players manipulate these machines through more than 120 distinct spatial puzzles set across a theatrically styled cityscape, with each character offering unique movement abilities that inform how puzzles are approached and solved. The narrative threads together themes of ambition, camaraderie, and setback as the trio works toward forming a band and performing on a major stage. Puzzle complexity increases progressively, demanding careful spatial reasoning and an understanding of each machine's particular mechanics. The game features an original soundtrack that has received award recognition, complementing both the visual aesthetic and the music-driven premise throughout the campaign.
