MonMon Masters Service Center UPDATE NOTE
2026.07.27 Update Notes


Hello, this is the MonMon Masters Development Team.

We would like to express our deepest gratitude to all the Masters who always show such warm interest and love toward MonMon Masters. In this v1.4 update, the "Exchange" system opens its doors — a way to reliably obtain new companions through effort, without relying solely on hatchery rates. We have also prepared a monthly subscription product packed with generous benefits, as well as a "Nightmare" difficulty Field Challenge and more, all to create a more comfortable growth environment.


📢 v1.4 Content Update Notice

The new version (v1.4) containing new content and convenience features has completed app store review, and a "no-maintenance store update" has now been distributed without any separate server maintenance.We recommend visiting the store you use (Google Play Store / Apple App Store) right now to update the game to the latest version.


[Content Open Schedule]

  • All update content except for Exchange, new MonMon, and chat improvements: Applied immediately upon completing the app update from the store
  • Exchange content, 3 new MonMon, and chat improvements: Official opening on Pacific (PDT): August 06 23:00, Eastern (EDT): August 07 02:00


Please note that after the server update to the latest version, Masters who are currently connected to MonMon Masters may experience a temporary disconnection.





New System: MonMon Exchange



The MonMon Association's exchange event is now open. In the newly added "Exchange" tab in the hatchery, you can register the MonMon you've been collecting as materials and exchange them for powerful new MonMon.


* The Exchange system unlocks upon reaching the "Green Meadow" field.

* Through the Exchange system, you can obtain the MonMon you want for certain by fulfilling the conditions, without relying on hatch rates.

* MonMon you've come across in the field make excellent exchange materials. MonMon designated as exchange materials will display an "Exchange Tag" on the list and battle formation screens to prevent accidentally consuming them.

* If not cancelled at least 24 hours before the free trial ends, it will automatically convert to a paid subscription. Cancelling during the trial period will not result in any charges. Subscriptions can be cancelled in Store Account Settings > Subscription Management.

* The 3 new MonMon featured in this Exchange content do not currently appear in the Hatchery and can only be obtained through "Exchange." (If additional ways to obtain them are added or changed in the future, we will announce this in a separate notice.)



Platinum Tamer License (Monthly Subscription)


A monthly subscription product has been officially added to support the comfortable growth of Masters who play consistently every day.


* Key Benefits: All battle XP gained +40%, All battle Gold gained +20%, Multi-Battle Ticket daily free recharge +70 (daily max 100), Daily Energy 100 Storage delivery

* Automatically renews on a monthly basis, and a 7-day free trial is available upon first subscription. (Please refer to the in-game shop for details)

* If not cancelled at least 24 hours before the free trial ends, it will automatically convert to a paid subscription. Cancelling during the trial period will not result in any charges. Subscriptions can be cancelled in Store Account Settings > Subscription Management.



Field Challenge "Extreme" Difficulty Added



* A new Field Challenge difficulty awaits our Masters. Clear it to obtain high-value rewards such as Ancient Eggs and Sacred Eggs. Take it on now!

* Field Challenge has been improved so that MonMon of Common to Rare rarity now drop, and these MonMon can be used as Exchange materials.




Balance Adjustments and System Normalization

* Skill and Hit Count Normalization: A bug was identified and fixed where certain MonMon — including Oniquito, Nanageck, Squidling, Punchmush, Flanix, and Bonltese — were hitting 1–2 more times than specified in their skill descriptions. An issue where basic attacks were intermittently mixed in during skill casting has also been fixed.

* Advanced Quest Reward Adjustment: Reward balance has been readjusted so Masters can enjoy MonMon Masters more comfortably every day. To allow smoother acquisition of Multi-Battle Tickets — which are needed most frequently — in place of Tamers League tickets that tend to accumulate with relative ease, the Advanced Quest reward has been changed from 1 Tamers League Ticket Refill to Energy 50 + Multi-Battle Ticket x10.

* Canyon of Wind Boss Gimmick Adjustment: The boss's Rage passive, which charges upon receiving non-critical damage, was judged to not be meaningfully impacting boss strategy, so the Rage passive trigger condition has been made more sensitive. Since this boss takes double damage from critical hits, formations focused on critical hits can still clear the boss with minimal damage from Rage.

* Fixed an issue where the resurrection buff upon death was being removed when affected by a "Duration Increase" effect.

* Fixed an issue where Rochino's damage block buff was only being applied to the same target. Rochino can now correctly grant the damage block buff to multiple allies when hit multiple times by a skill.

* Improved so that when a target leaves combat during a multi-hit skill, the remaining hits will seek a new target and continue. (Applicable MonMon: Martial Bear, Animogi)

* Fixed an error where stat increase/decrease effects (stacks) gained during combat were intermittently being retained when a MonMon left combat and revived. The intended behavior is for stat change effects that occur during combat to reset upon leaving combat, but in previous versions some stacks were temporarily maintained until the next update point, causing unintended behavior. With this fix, MonMon will always enter combat with stat change effects reset upon reviving after leaving combat.




Growth and System Convenience Improvements



* You can now select multiple MonMon at once and Bulk Rank Up more conveniently, without having to register material MonMon one by one.

* The batch level-up convenience feature for leveling up multiple MonMon simultaneously has also been improved! We will always do our best to provide Masters with an even more comfortable gameplay experience.

* A multilingual translation feature has been introduced to the chat window so Masters can communicate more smoothly with global players, and a new feature for sharing useful Runestone information with each other is also being unveiled.

Response to Illegal Program Users

To ensure that our Masters' hard-earned efforts are never wasted, we have further strengthened the verification logic that blocks abnormal gameplay within the game.

Accounts in which abnormal values or manipulation are detected will be subject to strong sanctions including permanent bans without exception. For all Masters who play fairly and honestly with genuine effort, we promise to continue thorough monitoring and transparent sharing of sanction status going forward.



Bug Fixes and Optimization

* An issue where the hatchery was intermittently inaccessible and an issue where rune set icon images appeared broken have been fixed.

* An issue where "Storage" text was incorrectly displayed in the top-left of the MonMon possession screen, and a UI error where the breakthrough value overlapped with the MonMon's star icon have been fixed.

* An error where dungeon boss HP and the continuous battle queue were displaying abnormally has been fixed.

* Typos in some skill tooltips have been corrected.


Official Discord Announcement

The MonMon Masters development team avoids chasing short-term results or one-off operations. Above all else, we believe the most important thing is ensuring that our Masters' precious time and love are never wasted — by building a "sustainable game" and a "MonMon Masters that players can trust and enjoy for the long haul."


The Official Discord is more than just a channel for announcements — we plan to build it into a comfortable space where the development team directly listens to and responds to the voices of our Masters. Special events and rewards exclusively for our Discord Masters will also be prepared on a regular basis.


Every piece of honest feedback our Masters leave behind is a precious foundation that helps us build a better game. We sincerely ask that you join us on the long journey ahead for MonMon Masters.
