The well
- Polycubes fall into a lit well seen from above. Slide them across the floor and turn them about three axes.
- Fill a whole floor (every cell of one plane) to shatter it. Planes above settle down.
- Two planes at once is a COLLAPSE, three a TRIPLE COLLAPSE, four a QUASAR.
- If a piece locks above the rim, the well is full and the descent ends.
The objective
- Glowing ORIGIN cubes are seeded in the lower planes. Shatter the planes they sit in to purge them.
- Purge every origin cube to clear the stage. Two stages per world, fifteen worlds, then the endless ABYSS.
- Worlds 5, 10 and 15 hide a boss. Shatter the planes holding its matter to wound it.

PLUS ✚P
- Five flat pieces from world 1. Three twisted pieces that do not lie flat join later (sooner on harder difficulties).
- Two five-cube exotics appear from world 7 if you carry the Exotic Lattice relic. They score double.
Reading depth
- The ghost rim on the landing plane and the column beams show exactly where the piece will land.
- The lowest unfinished plane glows; a plane that is nearly full pulses with a "to go" count.
- The depth gauge on the wall marks the danger band (top three planes). The mini-map top-right is a height map.
- X-ray turns cubes above your landing plane to glass. Peek tilts the camera for a second.
Controls
- Keyboard: ←→↑↓ move · QE spin · WS tip · AD roll · Space hard drop · Shift soft drop · C deck · V peek · X x-ray · R reset view · Esc pause · M mute. Remap everything in Settings.
- Touch: drag the left pad to slide one cell at a time; the right column spins, tips and rolls (hold to repeat); DROP slams the piece; tap the well to hard drop; drag the sky or use two fingers to orbit; pinch to zoom; double-tap the sky or press ⌂ VIEW to reset the view.
- Mouse: drag the sky (or right-drag, Alt+scroll, a sideways trackpad swipe) orbits the well a full 360° and it stays where you leave it; scroll to zoom; R, ⌂ VIEW or a double-click on the sky resets it. Gamepad: right stick orbits, click it to reset.
- Your view steers: moves, tips and rolls follow the camera — left is always screen-left and tip forward always tips away from you, whichever side you orbit to.
Score and salvage
- Planes score more when cleared together. Consecutive clearing pieces build a combo; back-to-back multi-plane clears earn ×1.5.
- You earn ✦ SALVAGE for planes, purges, stages and bosses. Spend it in the shop on cube rims, beams, glass, shards and camera packs.
- After each world you draft one of three relics. Every relic does something real; none changes where a piece lands.
- Nothing is ever taken away. Resets and wipes never claw back what you have earned.
