Built to Scale (組み立て Kumitate "Assembly"?) is the 12th minigame in Rhythm Heaven Fever and the 97th minigame in Rhythm Heaven Megamix. This game is about assembling Widgets together by launghing a red rod to them. A sequel later unlocked is known as Built to Scale 2.


BTS fever gameplay
A red rod will begin to bounce on the blocks. When it reaches the red block, the player must bounce the rod by pushing the block up. The player must continue doing this for as many times it bounces to the red block. When the two widgets
appear, the player must be ready for when the red block starts to back into its end. This signals that the player must spring the rod toward the two widgets.


Rhythm Heaven Fever

  • A: Bounce Rod
  • A + B: Spring Rod

Rhythm Heaven Megamix

Button Mode

  • A: Bounce the rod
  • B: Spring the rod

Simple Tap Mode

  • Tap: Bounce or spring the rod

Timing Notes

  • Hit: The rod is perfectly bounced and goes on another block. While pressing A+B, the spring hits the rod and hits squarely into the squares and connects them together.
  • Barely: The rod slightly bounces on the block. For pressing A+B, the rod will slightly fall down while touching the spring. A barely counts as a miss.
  • Miss: The rod falls down on the block and never make contact with squares while rolling around and disappear.

Defective Widget
A Rare Square
I work in product testing. My company doesn't make a lot of defective products, but when we do, I'm NOT supposed to sell the bad parts to collectors for a lot of money. Oops.

Skill Star

When it's the fourth order of widgets in medium speed, spring the rod toward the second widget perfectly to collect the star.



  • This is the third time a Built to Scale game has appeared in the Rhythm Heaven franchise, with the other two in previous games.
  • This is the only Built to Scale game that has reappeared in Rhythm Heaven Megamix while the GBA & DS versions didn't make a return at all.
  • In Fever, the letters A and B light up when you shoot the rod into the widget, but in Megamix, only the letter B lights up because instead of using both buttons, you only use the B button.
  • This is one of a few Rhythm Games to have its title card changed between games.
