A black hole turns at the edge of the screen, and everything is falling toward it. Rings rise from the dark. Tap them before the black hole swallows them, and miss too many and your run is over. At the center of Ringularity is a real-time ray-traced black hole that bends the stars around it, reacts to your streaks, and draws closer as your score climbs. Go far enough and the view swings to the far side, where a small crew is trying to fly out of the same pull. You steer their ship through the asteroid field while their story unfolds, though they have no idea you’re there. • A living, ray-traced black hole rendered in real time • Fast one-tap gameplay built around chasing high scores • Story chapters where you pilot the crew’s ship • Streaks and multipliers that reward timing and nerve • A global leaderboard with no account or sign-in • Three free runs every day, or unlimited play weekly or for life, with Family Sharing Quiet, weightless and relentless. This is Ringularity. --- Toggle music and sound effects by tapping the points counter at the top right. Unlimited: $0.99/week, auto-renewing until cancelled in your App Store settings, or $4.99 once for Lifetime.
