Atoms

Atoms is a Black Box-style game with multiple difficulty levels and time-based scoring. Easy has six atoms hidden in a 10 x 10 grid, intermediate has eight atoms hidden in a 10 x 10 grid, hard has 10 atoms hidden in a 16 x 16 grid, and impossible has 14 atoms hidden in a 16 x 16 grid.

Gameplay consists of shooting rays into the grid to determine where the atoms are, judging based purely on where the ray emerges. Unusually, scoring is based on the time taken, not the number of rays used. The game ends once all atoms have been correctly marked, but there is no penalty for incorrectly marking a space; the game will simply continue until all spaces have been correctly marked.

The game was distributed as shareware, but without missing features.
