Evaluation

Mamon King launched on December 10, 2025 as a complete monster-raising RPG. Following launch, the developer issued three patches in quick succession: a balance and quality-of-life patch on December 16, 2025, a feature patch adding an Achievements System and Self-Legend Battles on December 23, 2025, and a follow-up refinement and crash-fix patch on December 26, 2025. These post-launch patches are typical polish and maintenance work following a new release. The store description presents the game as a fully featured, self-contained product with 38 Mamons, 170+ skills, and a complete gameplay loop. No DLC has been listed, no future content has been announced, and the developer has made no statements about plans for additional expansions or updates beyond the initial post-launch fixes. The game launched as a finished product.

About this game

Aim to become the strongest king with uniquely charming monsters!

Players are special beings who can connect with Mamons (monsters) summoned from another world. Raise and train your Mamons with kindness, and sometimes strictness!

After winning countless tournaments, when you defeat the strongest Mamon, you will become the world's king: the Mamon King!

*38 Unique Mamons

Mammon boast distinctive appearances, each excelling in different training areas and possessing varying lifespans. Grasping their traits is your first step to victory.

*Over 170 Skills

Mamon's signature skills go beyond mere attack and defense, creating deep strategic depth. Master evolving skills through repeated use to forge even more powerful weapons.

*Experience the Ultimate Tactical Battle in 1-on-1 Command Combat

It's not just about attacking, defending, buffing, or debuffing. Using skills consumes SP, and more powerful skills demand greater SP—or even greater sacrifices. Timing your moves will decide your fate.

Experience unparalleled tactical depth in this 1-on-1 command-based battle system, designed to be accessible yet offering the most intense strategic gameplay.

*Strengthen Your Mamon Through Training, Tournaments, and Expeditions

Training isn't the only way to hone your Mamon—it's also about deciding what to do each week at home. Mamon grows stronger not only through tournaments against rivals but also via Expeditions, where you advance through uncharted lands rumored to hold ancient Mamon in a board game-style format.

*Your Unique Mamon

A Mamon's potential blossoms through your skill and luck. Inheritance Summoning passes on the power of your trained Mamon. And with help from a shady scientist or a muscle-bound trainer, your Mamon might gain powers beyond its natural limits?

The monster-raising game set on a ranch has evolved!

Experience a new kind of raising in Mamon King!
