About the game

Geometry: Black Ball hands you a rolling ball and ten obstacle courses to clear. You choose a course from the selection screen, where each button carries a small face showing how tough that run is, and the action starts right away.

Mid-run, tapping Space or the right mouse button reverses the direction gravity pulls the ball, sending it to the opposite side of the track. Line up each flip so the ball slips past what blocks the way and crosses the finish. Later courses leave less room and ask for sharper timing. A shop sells skins that change the ball's appearance.

How to play

  • Pick any of the ten courses on the selection screen; the faces on the buttons hint at the difficulty.
  • Press Space or the right mouse button to reverse gravity and shift the ball to the other side.
  • Clear every obstacle and reach the finish line to complete the course.
  • Visit the shop to buy a skin for your ball.
