Sticky Mat is one of the small Scritchy Scratchy gadgets that becomes much easier to understand once you stop viewing the automation layer as a pile of separate unlocks. Its job is simple: it keeps tickets stable when the fan is part of your setup.
The short answer
Sticky Mat prevents tickets from being blown around by the fan. That matters because the fan is useful for pushing tickets through the system, but without control it can also make the setup harder to manage.
Why players search for this gadget
Sticky Mat is exactly the kind of term that generates wiki-style searches. The gadget sounds minor, but once multiple systems interact, small control tools make a big difference to consistency and throughput. Players usually look it up when the automation layer starts feeling more chaotic than helpful.
When it matters most
It matters most once the fan is doing real work in your setup and you want fewer accidental movements. At that point, the question is no longer just whether a gadget exists. It is whether the setup is stable enough to support repeatable runs without constant correction.
