HYPERTOWER

Every piece spawns already tumbled through a 4th axis — most of it hanging off the plane you can actually build in, rendered as faint ghost cubes. Rotate it back flat before it lands, or land it half-scrambled and only the flat cells become real. Stack layers, clear them, build the tower as high as you can.

move — slide the piece across the footprint
1 · 2 · 3

rotate in XY / XZ / YZ — the ordinary 3D turns. Never changes alignment.

4 · 5 · 6

rotate in XW / YW / ZW — the only moves that can pull a stray cell back to the w=0 plane. Watch the alignment readout.

drop

hold to soft-drop, tap hard-drop to slam it down — however flat it is when it lands is what locks in.
