Project P.I.T.T. Panels: Why They Fall & Fixes
Panels are the building block of every factory — and the single biggest source of “why did my wall just fall over”. The rules, the variants, and the fixes.
The three panel types
| Type | Levels | Use |
|---|---|---|
| Panel | 1–3 | Standard square building piece (2 kg — also useful scale filler) |
| Cushion | 1–2 | Soft surface: products stop bouncing off — essential where a lane feeds a cash register |
| Slick | 1–2 | Low-friction surface: products slide — chute floors, speed sections |
All three obey the same sticking rules, and all are carried faster with the Panel Rack, a multi-level upgrade added in update 1.0.5.
Why panels fall over
Short version: panels only hold after the sticky tools upgrade, and only when placed against the floor or against something already stuck. The developer’s own FAQ answer to “how do I make panels stay?” is exactly that. If your build collapses:
- No sticky yet — it unlocks right after panels; keep feeding.
- Floating anchor — the chain’s first piece must touch ground.
- Stuck to a loose object — the anchor itself has to be stuck.
- Phase-change rubble knocked it loose — see debris cleanup.
Placement craft
- Lay pieces flat with a quick double-tap of reset rotation (G) — a 1.0.5 addition that ends the fiddly-rotation era. Free rotation stays on middle mouse, snap on R.
- Build a V-funnel into a fan for your first lane; upgrade to full walls only where product actually escapes. Pretty geometry second, containment first.
- Cushion where product lands, slick where it travels. Bounce is the top cause of leaking lanes; friction is the top cause of slow ones.
- Panels read 2 kg each on the weighing platform, so a stuck-panel box doubles as the community-favorite carrying container for the 200 kg puzzle.
Wall markings
If you notice markings on walls: the Sponge tool wipes them for a small payout, and some markings are only visible under the UV flashlight late in the secret route. Don’t sponge UV clue areas before reading them — the elevator code clues are wall markings too.
