Transball

Transball is a freeware gravity-based arcade game for DOS, standing in the long tradition of "thrust" titles that trace back to games like Gravitar and Thrust. You pilot a small ship through enclosed caverns where inertia and gravity fight your every movement, so simply holding position over a spot demands constant, careful correction of thrust rather than a casual tap of the controls.

The core loop revolves around threading your craft through tight tunnels, dodging or destroying hazards, and manoeuvring a ball or payload to its goal without crashing into the walls. That combination of precise physics and unforgiving level geometry gives it the same tense, one-more-try appeal that made the gravity subgenre a cult favourite among players who like their arcade games to demand a delicate touch.

As a small independent effort it never chased mainstream attention, but it holds up well for what it is: a tightly focused physics challenge that rewards patience and a steady hand. If you enjoy the momentum-driven flying of the Thrust lineage, it remains an accessible and satisfying example of the form.
