Built to Scale 2 (組み立て2 lit. Assembly 2) is the 38th minigame inRhythm Heaven Fever. It is the sequel to Built to Scale. In this sequel, the widgets have increased so well that the factory has ordered more so you'll have to deal with assembling three widgets this time. Are you hard enough to put them together?
The only visual change is that the background is now teal.
The gameplay is nearly identical to that of the first Built to Scale; bounce the rod on the when it hits the red block, and shoot it into the Widget parts when they line up. The major difference is that three Widgets must be assembled in each sequence; the third Widget rod comes from the left-hand side and must be flung into the Widget parts when it reaches the red block. The speed of the song, and therefore bouncing speed, also changes as the third rod is bouncing, and stays until the next third rod of a sequence. This leads to the tempo changing many times throughout the song.
A: Bounce Rod
A + B: Spring Rod
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.
