Solaris (Atari 2600)

Solaris was a game for the Atari 2600. The player pilots a space ship through a field of square dots. Every dot the ship reaches disappears and the player is awarded points. The objective is to clear the screen within a predetermined time limit and without getting shot by aliens. After ten levels, completing a bonus level yielded a letter. There were six bonus levels that spelled the word Helios.

At higher levels, the ship had to pass a dot twice to make it disappear. As the player completed more levels, the time available for completing a level decreased.
