"Mamon King" is a monster-raising simulation where you aim to become the King. Battles feature simple turn-based command combat, yet each monster possesses unique skills. Combined with the SP required to activate these skills, this creates intense strategic gameplay that anyone can easily enjoy.

Prices
The United States storefront in every case, so this compares stores and not countries.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Aug 15 → 0.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
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!

1500円で購入して15時間遊べたので、値段なりの出来でした。 大体の方が2体目に能力を引き継いで、そいつでマモンキングになって終わりって感じじゃないかな? 他の方も言及されていますが、薄味かつ作業感強めです。 そんなに期待して買うゲームじゃないので、少額でちょっとだけヒマをつぶしたい人向け。 20時間くらいなら夢中になれるかと思います! ◇良かった点 ・倍速戦闘が実装されていることで、作業のしんどさが少なかった ・とにかく全体的にシンプルでムダが排除され、分かりやすかった ◇改善できそうな点 ・自分のマモンの強化にCPUのマモンが付いてこれず、終盤は一方的な蹂躙が始まる ・最終的にほぼオールS・SSと言ったステータスになるので、ちょっと没個性気味… ・シンプルゆえできる事があまりに少なすぎて、速攻で飽きてしまう 次回作にも期待してます。
Plays and feels like a ps1 game really enjoyed it, buy it on sale though
カジュアルに楽しめて面白かった!

面白いゲームだけど敵が使ってくるときの麻痺、スタンが強すぎてキモムシとキノコが嫌いになりました
めちゃくちゃ人を選ぶと思う。話題性だけに食いつくと痛い目見るかも。ゲーム性はしっかりと把握したうえでの購入をお勧めします。 ペルソナの絆レベル上げるためにひたすら話しかける工程や、FE風化雪月の授業組んでひたすら生徒のステータス上げが苦行じゃないならいけると思う。 このゲームのやりこみ要素はやりこみたくない要素ですね。結構、いいとこまでいって寿命迎えると結構萎える。やり直そうとはならないかな。 よしなまは好きなので新作も期待してます。
価格を見て考えるととっても面白い。 育成要素や自由度を鑑みてもストレスは非常に少ない。 少ないがゆえに長続きするかといわれるとそうではないのかも とはいえ、十分な満足感があるためこれにとどまらずモンスターや難易度を追加した正当進化が来ると嬉しいなと。
Pretty fun game, reminds me of the monster rancher games back in the day. Clean old school game design, The voyage mini game is a creative way to lvl up and still feel involved. This game has a ton of potential, if they add multiplayer to the game and let you battle friends I think that would be an awesome addition.
its ok
This game is a hidden gem.
2週目でクリアしました。ストレスフリーで面白かったです。値段も安いから手に出しやすい。 ただ育成に関して、マモンの寿命が少し長く、マモンの引継ぎありの2週目以降はかなり簡単に感じたため、そのあたりを調整すればもっと面白くなるかなと思いました。 ただそれでも十分に楽しめたため、次回作にも期待しています。BGMも良かったです。
