About this game

Fire rays into the grid and deduce the hidden atoms from hit, reflect and detour clues across 27 unique logic puzzles.

How to play

How do you play Black Box?

Click any port around the grid to fire a ray. A ray is absorbed (Hit) if it strikes an atom, reflects (Reflect) if it bends back to its entry, or exits at another port (Detour). Use these clues to locate every hidden atom, then mark the cells and press Check.

What do Hit, Reflect and Detour mean?

Hit: the ray travels straight into an atom and is absorbed. Reflect: the ray returns to the port it entered from. Detour: the ray leaves through a different port, shown with a matching number to its partner port.

Is Black Box free?
