Each level presents one or more colored signals, matching terminals, and a set of junctions that can be rotated between possible branches. Your job is to configure every switch so all signals reach their own destinations, then press Dispatch and watch the complete plan run. The first yards teach simple forks, but later layouts overlap routes and ask you to account for several travelers at once. A path that looks correct for green may quietly divert amber, so success depends on reading the whole board rather than solving one line in isolation. There are twenty-four deterministic levels, persistent unlocks, and a built-in hint that aligns one useful switch without completing the puzzle for you. Clear feedback distinguishes a dead end from a wrong terminal, making a failed dispatch useful evidence instead of a vague loss. Because every layout is deterministic, the challenge is entirely about reasoning; no lucky timing or random spawn can rescue a weak route.",[50,59,61],{"id":60},"how-to-play","How to Play",[55,63,64],{},"Click or tap any switch to rotate it through its available connections. On a keyboard, use the Arrow keys to move the selection and press Space or Enter to rotate the highlighted junction. Once every route looks plausible, choose Dispatch or press D. The signals travel together, and the attempt succeeds only when every color arrives at its matching terminal. Press R or use Reset to restore the current yard. The hint control rotates one relevant switch toward the solution, which is useful when a crowded layout has become difficult to parse.",[50,66,68],{"id":67},"tips-strategy","Tips & Strategy",[55,70,71],{},"Work backward from the terminals. A terminal often has fewer possible approaches than a starting signal, so identifying its required final segment can eliminate several switch states immediately. Next, trace bottlenecks: if two routes share a central junction, solve that junction before adjusting branches at the edges. Color is important, but topology is more important—temporarily imagine every route as the same color and mark which connections are physically possible. Before dispatching, conduct a manual audit from every start to every destination; do not stop after checking the route you changed most recently. When an attempt fails, read the result and change the earliest junction responsible for the dead end or mismatch rather than rotating several switches at random. Use the hint as a learning tool: after it changes a switch, trace why that orientation is necessary. On later levels, preserve any already-proven subroute and treat it as fixed while solving the remaining signals. This reduces a complicated yard to a sequence of smaller logic problems and prevents the common cycle of breaking one correct route while repairing another.",[50,73,75],{"id":74},"what-makes-it-distinct","What Makes It Distinct",[55,77,78],{},"Unlike a timing-heavy train game, Signal Switchyard lets you inspect the complete system before anything moves.
