Portal

Portal navigates a mesmerizing world where reflexes and precision are vital: you guide a ball to safety, dodging a relentless black hole through physics-based puzzles that demand skillful maneuvers and quick thinking. Each level presents a new, exhilarating challenge to escape its cosmic grasp.

Controls handle guiding your ball through each level, avoiding the relentless pull of the black hole while navigating physics-based obstacles. Because the black hole is relentless rather than a static hazard, maintaining continuous awareness of its position tends to matter as much as solving the puzzle itself.

It's worth treating the black hole as a constant threat to route around, rather than something to deal with only when it's close, since staying ahead of its pull tends to be easier than escaping it once caught. Studying a new level's physics-based layout before committing to a full route also tends to reveal the safest path rather than improvising blind.

Portal is a good fit for players who enjoy physics-based puzzle games with a genuinely tense, ever-present hazard driving the pace — free to play instantly in the browser, no download required.
