This guide walks through building a switch puzzle in UEFN using Switch Devices, a Teleporter Device, and a single Verse script. It covers two modes: a guided version that resets on a wrong press, and a non-guided version that checks the full sequence only after every switch has been pressed, with the solution defined entirely by an editable array instead of hardcoded logic.
