32 x pawn ray markers;
- 8 black, 8 white
- 2 red, 2 purple, 2 green, 2 yellow, 2 brown, 2 blue, 2 pink, 2 orange
5 x steel ball bearing atoms
1 x rectangular dry-wipe, plastic score board
1 x scoring board built into the box base
1 x black crayon
1 x rules leaflet

Players take turns to secretly set up a molecule of 4 atoms by drawing 4 circles on the small rectangular board/score board.

Other player(s) are experimenter(s) who try to deduce the exact positions of the 4 atoms by sending ‘rays’ into the black box and observing how they are deflected.


The experimenter discloses the input of their ray and is then told where the ray emerges. Ray input and output positions are identified by the numbers 1 to 32.

The information about each ray is recorded on the black grid in the black box using colour pawn ray markers. Experimenters may position steel balls in their grid to help visualise how the atoms might be placed.

Deduce a molecular structure using the least ray markers to win. Illustrations are included in the rules leaflet to explain deflection patterns. A compact, classic game.
