Kinkoid

Kinkoid is an independent adult game development and publishing studio based in Sofia, Bulgaria. Founded conceptually in 2015, it develops free-to-play browser and mobile-web games built around manga-inspired art, erotic visual-novel storytelling, parody, and lighthearted comedy. Its flagship title, Hentai Heroes—originally launched as Harem Heroes—debuted in 2016.

The studio operates under the Bulgarian legal entity Phoenix Media OOD and maintains an in-house production pipeline spanning concept development, narrative scripting, storyboarding, 2D character and background art, digital coloring, dynamic skeletal animation, and web and mobile engineering. Its games are designed for desktop and mobile browsers and use a freemium model, with free access alongside optional purchases for in-game currencies, collectibles, and event progression.

Alongside development, the studio publishes and operates its games globally through ongoing updates, quests, player events, localization, customer support, and community moderation.

The studio marked the tenth anniversary of Hentai Heroes in 2026 and continues to release live updates, patches, community communications, and recruitment campaigns.
