SignalBox
Keep the junction clear.
Set points, lock routes, watch blocks fill, and keep a fictional railway junction moving in a short, touch-first dispatch puzzle.
A deterministic game panel with plain-language reasons for every rejected decision.
Offline dispatch puzzle
Learn the panel one decision at a time.
SignalBox keeps the first station small enough to understand: set a point, request a route, then watch the same rules resolve movement and scoring.
Six scenarios
Start with a guided route, then explore conflicts, occupied blocks, locked points, late trains, and disruption recovery.
Explainable rules
Every rejection has a reason code and plain-language event, so the panel teaches through feedback instead of hidden state.
Replayable runs
Deterministic seeds make the same action sequence reproducible. Share a compact replay result when a shift is complete.
Fictional by design
A game, not an operating tool.
Track layouts, trains, timings, and rules are handcrafted fiction. SignalBox is not railway operating guidance, professional signalling training, or a live timetable.
