Hello, this is the MonMon Masters development team.

📢 v1.7.6 Content Update Rollout Notice

The new version (v1.7.6), which includes new content, has passed app store review and will be released as a "no-maintenance store update," without any separate server maintenance. We recommend visiting the store you're currently using and updating the game to the latest version.

Each stage comes with several tasks.

A new Profile Frame feature is added, letting you decorate your profile.

A 'Profile Frame' system is added, letting you express your individuality and commemorate the achievements you've earned. Play through a variety of content to collect and show off Frames all your own!

  • The Frame you're wearing is reflected identically not just on your detailed profile screen, but on every screen where your info is shown, including Chat and the Tamers League
  • You can check the unlock condition of any Frame you haven't obtained yet, in advance, from the Profile Frame menu
  • You'll be easily notified whenever a new Frame becomes available to earn
  • Once obtained, a Frame can be freely switched at any time

More Frames will keep being added alongside future content.



New System: Chat Report
A Chat Report feature is newly added to help create an environment where everyone can chat comfortably.
If you come across an inappropriate chat message, please report it directly from that message. Reported content is reviewed and handled by the Operations Team.

  • You can report another Master's chat message by tapping the Report button on it
  • A confirmation window lets you review what you're about to report before submitting
  • Available in both Global Chat and Tamers Club Chat
  • You cannot report your own messages
  • The same message can only be reported once

Reporting is a feature meant to keep the chat environment healthy. Please use it responsibly, as repeated false reports may result in usage restrictions.



1 New MonMon

One new MonMon joins the roster with this update.




Runestone Display Overhaul

The names and shapes of all six Runestone types are changed to a fresh new concept, so you can identify each type at a glance.



    • Rarity-based Runestone artwork is also refreshed for each type
    • Set Effects are now displayed separately in the bottom-left of the Runestone, alongside the Set's color

Combat System & Balance Adjustments

Combat System Adjustment

  • A MonMon's body size is now factored into range calculations. Previously, a MonMon's own size wasn't included in the calculation, so larger MonMon had an actual attack range that differed from what was displayed. With this adjustment, the felt range of some MonMon may change
  • The battle calculation method has been refined so that battle results are always reproduced identically

Balance Adjustments

  • Lapis's balance has been adjusted
  • Fixed an issue where Carrit's skill level wasn't displaying correctly

Bug Fixes & Optimization

  • Fixed an issue where the Revive buff triggered on death was blocked by a Healing Received Decrease debuff
  • Fixed an issue where Rank Up showed "no materials" even when the required materials were only in Storage
  • Fixed an issue where a different MonMon would open on a Dungeon boss
  • Fixed an issue where the Battle Pass daily reward count wasn't being tracked
  • Fixed an issue where Google account linking wasn't working
  • Fixed an issue where a revived MonMon's portrait displayed as grayed out
  • Fixed an issue where the rank shown on Club Raid chest rewards was incorrect
  • Fixed an issue where Club Quest and Tournament reward notifications weren't displaying
  • Fixed an issue where the presentation didn't play when a Runestone Set was activated
  • Fixed an issue where battles would end prematurely in certain Dungeons
  • Fixed an issue where the Mission list briefly displayed as locked
  • Fixed an issue where the previous wave's display carried over into the next wave
  • Fixed an issue where the close button on the Exchange guide window wasn't working
  • Fixed an issue where the Abandoned Tower reward display was misaligned
  • Fixed an issue where the Surprise Energy Package window's background wasn't displaying, making the content behind it tappable
  • Fixed an issue where the Costume preview on the Prologue screen wasn't changing
  • A number of other bug fixes and optimizations have also been applied
