Swell
osu!taiko swell
The swell is a circular hit object in osu!taiko beatmaps looking like a whirl. Upon reaching the white judgement circle on the left side of the conveyer belt, the swell will be displayed as a big circle, taking up the entire screen. At this point, players need to alternate between hitting the drum's centre and rim as fast as possible until the swell disappears.
It does not matter which part of the drum is hit first. Hitting the same drum part on repeat will not progress the swell. Failing to complete the swell will incur a health penalty, but will not break combo.
Judgement
Swells do not increment the combo counter, and do not recover the health bar in any way. Each successful hit on a swell only gives a static 300 bonus score, while a successful completion of a swell will reward the same amount of score as a finisher hit.
Trivia
- In Taiko no Tatsujin, swells are called denden.
- Due to technically being the same object type as spinners in
.osufiles and other game modes sharing the osu! mode's editor in osu!(stable), swells are sometimes called spinners too.
