Time every drop. Slice nothing. Answer at each checkpoint to reinforce the tower, or watch it narrow.
Subject
Stage
1
Drop the slab. It slides across the top of the tower. Tap, click or press Space to drop it. Anything hanging over the edge gets sliced off.
2
Chain perfects. Land it inside the glow line for a Perfect. Your combo grows, and from three in a row the slab grows back.
3
Clear checkpoints. Every few floors a timed question appears (123). A right answer reinforces: wider slab, slower slide. A wrong answer faults: narrower and faster.
4
Bank safety nets. Three right answers in a row earn a net that catches one missed drop. Press R to wager 2× on a question.
