Games that try to simulate real-world activities (like driving vehicles or living the life of someone else) with as much realism as possible. Simulators generally require more study and orientation than arcade games, and the best simulators are also educational.
Inspired by the Japanese puzzle game game where you drop round objects into a box. Adjacent balls of the same size will combine into the next larger ball. The goal is to drop and merge as many balls as possible before running out of space.
