How to play

Time each moving slab, keep its overlap, and build a narrowing neon tower toward the selected target height. Choose a target height, make your move, and use Restart whenever you want a fresh game.

Strategy tips

  • Place only while the moving coral slab overlaps the top slab; any unsupported edge is trimmed from the tower.
  • Landing within four pixels of the previous slab counts as perfect, preserves full width, and grows the bonus streak.
  • Use Space, Enter, the large Place slab button, or tap the tower; press P to pause.
