Draw the RailBall Physics

Draw the RailBall Physics is about building a track for a rolling ball. The goal sits somewhere in the scene, the ball starts elsewhere, and you assemble the route between them out of rails, pipes and a set of props: planks, springs, accelerators and bumpers.

The developer's description talks about drawing rails and pipes, while the instructions describe dragging props from a panel into the scene, so expect construction by placing pieces. The ball stays put until you tap start. Any placed prop can be dragged to a new position or deleted, so a track can be adjusted rather than rebuilt from nothing. According to the developer there is no time limit, and the game is pitched as a calm one for short breaks, with the advice to think like an engineer while you build.

Drag props from the panel and drop them into the scene to build a track. Tap the start button to launch the ball and find out whether your track carries it to the goal. To change the layout, drag any placed prop to a new spot, or tap delete to remove it from the scene.

Since placed props can be moved or deleted, it costs nothing to build roughly first and refine afterwards. Think about what each prop is for: planks and rails give the ball a surface, while springs, accelerators and bumpers change how it moves. With no time limit, there is no hurry to press start.

A physics track-building puzzle with a rolling ball. Landscape frame (1920 by 1080). Props are placed by dragging, and the ball is launched with a start button. The developer states that there is no time limit.

Line to Goal : Draw The Path also steers a ball to a goal, this time along a line you draw, and Scribble World: Drawing Puzzle uses pencil lines alongside seesaws, trampolines and bubbles.
