Waifu Jam! Map-Battle Contest

Friendly and fun-loving demon queen Ironmouse joins forces with everyone's favourite osu! streamer BTMC for a new type of mapping competition, all based around the new hit Ironmouse & Camellia - Waifu Jam!

Read the news article for all the details, and check out the forum thread for the most up-to-date info.


Mappers, don't get it twisted. This isn't your everyday mapping contest with the usual set of judges and criteria benchmarks. Pfft! This time, you can be the judge!

After a preliminary screening phase, the top 16 submissions will be placed in a 1v1 tournament-style bracket to compete live on BTMC's stream. From there, it'll be up to the community to vote and decide which maps proceed through the bracket!

Each stage of the bracket will focus on a different section of the map:

Bracket stage Beatmap section
Round of 16 00:00 to 00:44
Quarterfinals 00:44 to 01:22
Semifinals 01:22 to 01:50
Grand Finals 01:50 to 02:47

Because of this format, you'll need to create a map of the song below where each of these sections stands out individually!
