Follow Mumei's journey to learn all Hololive talent names in this match-2 card game. Keep in mind this is not your ordinary match-2 game. All cards that are matched can be used to activate special effects that will affect the placement of cards on the table, so keep your eyes open!

Additionally, each Council member has a Unique Skill they can activate after matching a number of cards. Use these skills to help you obtain victory!

The game features a Story Mode, where Mumei will interact with her fellow Council members and challenge the limits of her memory.

Defeat Council members in story mode to unlock them in other game modes.

Challenge yourself in Time Trial Mode, to see how fast you can match those cards in each of the levels.

Take it easy and practice in Solo Mode, where you can choose a Council member to play as, select the cards you want to use and go at it at your own pace.

Feeling competitive? See how you fare against the other Council members in VS Computer mode or play against a friend in VS Hooman mode (local multiplayer).

I kinda find it funny that in this game, the catchphrase you used for Mumei is "I forgot"

It fits the game! XD

Also... If I'm not mistaken, when I started grabbing audio clips for each talent the girls had only a few months since debut. I think "oh hi" was not a thing back then. I may be wrong though.

Hi hi! Found this game because Mumei is going to play it on stream tomorrow. I love it a lot! Even the boys are included! Minor nitpick though, since Flare got a new base outfit now, she prefers it if people would use her new model instead of her old one in games/fanarts/memes/clips. So I wonder if you would change her portrait to the new one? It's available in the Hololive official website.


Thank you for playing! I'm glad you liked it!

About Flare, yes, her new outfit is in the list of future updates for the game, together with some difficulty adjustments and possibly adding the new holostarsEN boys. Thank you for the feedback!

Nice game.

Very minor but having the zip include a folder for the game would be nice so that extracting it to a folder that isn't empty won't cause a mess.

Also Staff and Other being same category isn't ideal.

Thank you for the ZIP folder suggestion. I'll keep that in mind for the 1.1 release!

I had to group Staff and Other because they're too few members in each group (2 each) to have them in separate categories. In version 1.1 AZKi will move to Gen 0 and Nodoka will join Staff, so this category will be renamed Staff and HOPE. :)

I really love this game!

Encountered a bug during one match though. We got dealt new cards, making a single row. Sana used her ability and froze, because there was no 2x2 area available. Had to quit to menu.

Oh wow, I gotta look into this particular case!

Thank you for reporting!


Awesome game! Memory games are so fun and relaxing. I love the new twist you put on it! All the polish on it is wonderful, too!

I'm not sure how concerned you are with typos, but there was one I found on Day 8: VS Baelz. Bae says "I heard ya'been studying heaps about out Hololive fam!" I'm pretty sure it should read "our Hololive fam." Just wanted to bring it to your attention that it was there. No pressure or anything though.

Keep up your awesome work!


Hey, I'm glad you enjoy my game!

Thank you for pointing out the typo! I'll add it to the list of stuff to fix for the next game patch!

Five stars! 

Thank you! I'm glad you liked my game!
