Evaluation

Cult of the Yellow King launched into Early Access on December 12, 2025 and has received a steady stream of updates since then: patch 0.2 on December 27, 2025; a development roadmap on December 21, 2025; Update 0.3 on March 20, 2026; a major public beta for Update 0.4 on June 26, 2026; and the full 0.4 release on August 15, 2026. The 0.4 update introduced a redesigned Relic System, a new Generator, story Arc III, Steam trading cards, and major progression rebalancing. On September 5, 2026, the developer announced that the game will leave Early Access and fully release on October 12, 2026. They described actively working on new buildings, relics, achievements, and polish for the full release — noting they planned "a few new things" that turned into "a lot." The August 15 update also confirmed plans for 21 total relics in the finished game, along with a teased Story Arc IV, indicating meaningful content remains to ship before or at the 1.0 launch. A demo update was released alongside the announcement, available until one week after the full release. The developer is a small three-person team who have communicated consistently and transparently throughout the Early Access period. The 1.0 release date is confirmed for October 12, 2026.

About this game

Build your cult. Spread the mold. Watch the sky bloom with yellow eyes, click to decay beautifully. 


A yellow stain blooms at the edge of your vision.

It whispers your name in the language of rot.

You obey.

Cult of the Yellow King is a cosmic horror idle game where you command a cult to summon the Yellow King.

With every click, you surrender another fragment of yourself: memory, tongue, flesh. Each prayer gnaws at your humanity.
Each sacrifice bleeds you hollow.

IDLE MADNESS

Generators whisper secrets that scar.
Upgrades demand teeth, skin, sanity.

A NARRATIVE OF UNMAKING

Unlock fragmented tales of dread as you progress.
Each milestone a fresh horror.
Your skin crawls. Walls grow eyes.
The sky bleeds yellow.

PRESTIGE THROUGH DAMNATION

Ascend by shattering your progress. 
Choose an elder curse. Begin again, deeper in devotion.

SOUNDS OF THE VOID

Black metal dirges by Merhum.
Hymns for the end of reason.

THE KING AWAITS

The mold has rooted in your throat.
The stars blink shut.
He approaches…

Click, and let the beautiful decay consume you.
