Line on Hole

Line on Hole is a physics-based "Draw-to-Solve" puzzle. The technical core involves "Gravity-Vector Manipulation." You do not control the ball directly; you modify the environment by sketching static hitboxes (lines). It tests "Newtonian Prediction," requiring players to visualize how a rolling object will interact with friction, slopes, and drawn barriers to bypass obstacles and fall into the target zone.

You see a ball and a hole separated by obstacles (walls, spinners, gaps). Your goal is to guide the ball into the hole. Interaction is "Freehand Drawing." Draw a line to create a bridge, a ramp, or a shield. Once drawn, gravity activates. The ball rolls based on the slope of your line. You have a limited "Ink Meter." You must create stable structures that won't collapse under the ball's weight.

Solving complex stages depends on "Anchor-Physics." Lines drawn in mid-air will fall unless connected to a static environment block. Use "Hook Shapes" to latch your lines onto ledges. A pro strategy is "Velocity Dampening"—if the ball is moving too fast to enter the hole safely, draw a "Jagged" or "Rough" surface to increase friction and slow it down before the drop.
