Atom ChamberHidden matter. Visible clues.

Fire a beam. Follow the evidence. Find the atoms inside.

Read the invisible

Tap a numbered edge port to fire. Tap an interior square to mark an atom. Place the exact atom count, then check your theory.

Hit

An atom directly ahead absorbs the beam.

Return

The beam returns to its entry port. An edge-adjacent atom or two deflections can cause this.

Paired numbers

Matching numbers connect entry and exit. An atom diagonally ahead bends the beam 90° away.

First experiment

Try opposite ports. A straight passage rules out atoms along that line; an H narrows your search. Crossing clues are stronger than one clue alone.

Controls & scoring

Tab to any square or port; Enter or Space activates it. Arrow keys navigate the board. Z undoes a mark. Fewer unique probes make a better result. Hints mark one real atom and label your result assisted. Equivalent atom layouts with identical beam outcomes are accepted.
