Built to Scale (組み立て Kumitate?) is the 12th minigame in Rhythm Heaven Fever and the 97th minigame in Rhythm Heaven Megamix. This game is about assembling Widgets by launching red rods at white squares. Its sequel, Built to Scale 2, is unlocked later on.

A red rod will begin to bounce on the blocks. When it reaches the red block, the player must press A to bounce the rod. The player must do this every time the rod lands on the red block to keep it moving. At the same time, two squares will gradually move towards each other. When the squares are about to meet, the red block will pull back. When the rod lands on the block in this position, the player must press A and B (just B in Megamix) to launch the rod at the squares, connecting them and assembling a Widget.



Rhythm Heaven Fever

  • Ⓐ: Bounce rod
  • Ⓐ+Ⓑ: Shoot rod

Rhythm Heaven Megamix

  • Ⓐ/Tap: Bounce rod
  • Ⓑ/Tap: Shoot rod

Timing Display

  • Perfect!/Ace!: The rod is perfectly bounced onto the next block. When launching the rod, it hits squarely in the center of the squares, connecting them.
  • Early!/Late!: The rod is bounced onto the next block, wobbling in the air and making a sound. When launching the rod, it will slightly fall down when touching the block.
  • Miss...: The rod falls off of the block. When launching the rod, it misses the squares and fails to connect them.

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

The Skill Star appears on the fourth pattern, where the Widgets move at a medium speed.

Challenge Land

Built to Scale appears in the following Challenge Train courses:



  • In Fever, the letters A and B light up when the red block pulls back, signaling the buttons that must be pressed. In Megamix, only the letter B lights up, matching the new controls for the game.
  • This is one of a few Rhythm Games from Fever to have its title card changed completely in Megamix.
  • This game combines the rod bouncing from Polyrhythm with the rod shooting from Built to Scale. The rods also resemble those from Polyrhythm, while the squares match the ones in Built to Scale.
  • The slowest BPM in this game (and its sequel) is the slowest BPM of any game in the series.
