About Mamon King
Mamon King is a monster-raising game in which you raise and train Mamons—monsters summoned from another world—and compete in tournaments. Win tournaments and defeat the strongest Mamon to become the world's king, the Mamon King.
Raise and train Mamons
The game features 38 Mamons with distinctive appearances, different strengths in training areas and varying lifespans. You decide what to do each week at home, and can develop your Mamon through training, tournaments and Expeditions.
Expeditions take you through uncharted lands in a board game-style format, where ancient Mamons are rumored to be found. Inheritance Summoning passes on the power of a Mamon you have trained. A shady scientist or a muscle-bound trainer may also help your Mamon gain powers beyond its natural limits.
Command battles
Battles are one-on-one and command-based. You choose when to attack, defend, use buffs or apply debuffs, while managing SP: skills consume it, and more powerful skills require more SP or greater sacrifices. Mamons have over 170 skills, including signature abilities that can evolve through repeated use.
Tournaments and growth
You face rivals in tournaments as you develop your Mamon. Its potential depends on your skill and luck, while the choices you make at home, in training and on Expeditions shape how it grows.
