These Find The Needle tips and tricks are the ones that measurably move the needle on a playthrough: keep the belts close to the haystack, run several lanes instead of one, and leave the scanners for last. The second half of the page is the list of mistakes that quietly cost you money, hay, and sometimes a needle.
Find The Needle tips and tricks that make the factory faster
- Put the Conveyor Belt directly beside the haystack. That single placement was the fastest route past $120/min in one playthrough, because the belt picks hay up and drops it without you walking back and forth.
- Run several belt lanes instead of one. Hay keeps flowing through parallel lanes rather than piling up in front of a slow machine.
- Break long belts into smaller mixed-size sections. Then one section can be deleted or re-routed without tearing down the whole line.
- Skip the Vacuum if you are chasing money. It holds more hay, but it unloads so slowly that the money per minute drops.
- Put the Generator in the middle of the build and branch Power Poles outward, so the poles do not eat the space your machines need.
- Add scanners last, after every other machine. Scanning slows the flow, so it belongs at the end of the lane, not the start.
- Move the robotic arms closer together as the pile shrinks. They lose reach when the hay they are digging has gone.
- Keep the Metal Detector for patrolling the pile. It is still useful for learning which side holds needles, though most needles sit too deep for it.
The placement rules behind most of these are in factory layout and the first production line.
Mistakes that waste money and hay
- Digging randomly instead of working the pile systematically. Start at the outer edge and work in straight lines; random digging leaves isolated pockets that are never cleared.
- Spending on manual upgrades and shovel cosmetics before any automation runs. The money is better spent on the first machine that works.
- Placing belts without checking the arrows or without checking that the machine they feed has power. Both errors look like a broken machine later on.
- Raising belt speed before the sell stand and the machines can absorb the extra throughput. More speed just moves the bottleneck.
- Assuming one scanner covers the factory. Any branch that rejoins the main line after the scanner, or any side line fed by a robotic arm, can carry a needle straight past the scanners to the stand.
- Deleting the save or dismantling the whole factory to test a theory. Keep the save, and record the needle count, the remaining hay, the Silo status and the scanner route instead.
That last one is why a missing needle has its own checklist — the diagnosis matters more than the guess.
