Draw ramps across a drafting board to guide a rolling marble into a catch ring. Play 24 levels in each of three difficulties. The 3D playfield supports touch and mouse, with keyboard controls and optional sound.
How to Play Chalkline Drop
Set the height of each chalk support by tapping a grid point or using the arrow buttons. Keep the ramp descending to the catch ring, leave room for the marble under bridges, and ease sharp drops on harder levels. Press Roll to test the path. Choose Easy, Medium or Hard, then pick a level. Clear a stage to move on, or use the restart button to replay it.
