You are a special being who can connect with Mamons summoned from another world. Raise a Mamon and enter tournaments, working your way toward the title of Mamon King.
Each week, choose how to spend your Mamon’s time: train its stats, rest, or take part in tournaments and expeditions. Training and event choices help shape its growth, while expeditions use a board-game-style route to explore new areas and encounter Mamons.
Battles are one-on-one and turn-based. Choose from each Mamon’s available skills, manage the SP they consume, and use skills repeatedly to evolve them. Mamons have limited lifespans; inheritance summoning lets you carry some stats and a skill into a new generation.
Reviewers who enjoy Mamon King often praise its approachable monster-raising systems, brisk pace, and the satisfaction of planning training and watching a Mamon grow. Some find the SP-based command battles offer engaging choices, while others consider them simple or repetitive. A recurring criticism is that training can become routine and there may be little to pursue after reaching the main goal; opinions also differ on how distinct Mamons and their builds feel.
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!
