Spectra Hall — Light & Optics Puzzle Guide
Spectra Hall is a relaxing optics puzzle. You bend and split beams of light to hit every target in the room. Across 100 levels the tools grow richer — mirrors, prisms, splitters — but the thinking stays the same. Here is how to approach any level.
How light behaves
A beam travels in a straight line until it meets an object. A mirror reflects it at the same angle; a prism can split or bend it. Your job is to route the beam from its source to every glowing target.
Core elements
- Mirrors — rotate them to steer the beam.
- Prisms — split one beam into several or shift its color.
- Walls — block light; route around them.
- Targets — every one must be lit to clear the level.
A reliable method
Start from the source and trace the beam one bounce at a time. Then start from a target and work backward to meet in the middle. Levels that look impossible usually solve when you place a single mirror one notch differently.
Hard levels
When several targets need different colors, use prisms to split the beam early, then steer each branch independently. Don't be afraid to undo and re-aim — Spectra Hall is about patience, not speed.
Hints
Stuck? Step away for a minute; the layout often "clicks" on return. And always check whether a target can be reached by simply extending an existing beam before adding new pieces.
