How to play
- Hidden atoms sit somewhere on the grid — you cannot see them directly.
- Fire a beam of light from any edge port and watch how it exits: a direct hit, a straight pass-through, a reflection back the way it came, or a bent refraction.
- Use the pattern of hits, refractions, and reflections across multiple beams to work out exactly where each atom is hiding.
- Mark every atom you have found to win — fewer beams used earns a bigger bonus.
Strategy & tips
- A beam that passes straight through tells you an entire lane is clear — use that to rule out large parts of the grid fast.
- A reflection means the beam bounced right back without entering — atoms near your entry point are blocking it, but a reflection alone gives no coordinates.
- Refracted beams bend around atoms without hitting them — the atom sits next to the bend point, not on the beam path itself.
- Fire beams from ports on different sides early to build overlapping clues before committing to a guess.
FAQ
How do you play Prismbox?
Fire a beam of light from any edge port (click, tap, or arrow keys + Enter) and use how it exits — hit, pass-through, reflection, or refraction — to deduce where the hidden atoms are.
What is this game based on?
Prismbox is inspired by the classic deduction game Black Box, reimagined with a light-beam theme and daily seeded puzzles.
What does a refracted beam mean?
A refraction means your beam bent around an atom without directly hitting it — the atom sits next to the bend point, not on the straight path.
