Neon Stack
Stack the blocks precisely. Racing, action, puzzles and duels to enjoy on phones or computers.
Stack the target floors and meet the displayed core and roof goals. Only the overlap stays. Keep width and depth at least at the shown minimum. On core chapters, every floor must cover the marked core. Roof goals check the final width and depth. A perfect placement widens the active axis up to its current limit. No time limit. Guides: solid ivory outline = current support; amber dashes = moving slab projected onto the support plane; teal dashes = required roof; red = core or failed placement. Press Place or Space once per floor. Release before placing again. Placement uses the alignment you see; holding does not repeat. X moves side to side, Z moves front to back. New game starts at chapter 1. Earned chapters stay available. Dimensions are percentages of the foundation; the record measures roof area. Harbor ambience, rail taps and ceramic chimes are synthesized locally. Press Play to enable sound. 2D fallback view is active with the same rules.
