Rubber Doodle: Finding a Ball’s Route with Elastic Lines

Rubber Doodle is a physics puzzle where drawn lines become elastic bands. The game description gives a direct objective: guide the ball into a cup. Along the way, the player can stretch a band, let it snap, wrap bands around pegs, and use them to launch or redirect the ball. The hand-drawn stages give those actions a playful surface, but the central question stays practical: what route will the next line create?

Highlights to notice

• Drawn bands can stretch and release like a slingshot.
• Pegs provide points around which bands can be arranged.
• The ball’s destination is a cup.
• The listed game includes 75 stages and three tutorials.
• Later obstacles named by the source include saws, lasers, TNT, portals, keys, boost arrows, and upside-down gravity.

Those details come from the game’s own description. They establish the puzzle’s vocabulary without implying that every stage contains every obstacle.

Build a route rather than a picture

Drawing is the way to set up movement, so each line has a functional role. A band can hold, stretch, or release; its placement changes the space available to the ball. The player can compare the ball, the pegs, and the cup before deciding where a line might help. Exact physics outcomes are best learned from the game’s feedback, since a small change in placement may produce a different path.

The cup offers a clear endpoint, while the pegs help organize the middle of the route. That relationship gives each board a visual beginning, a set of possible supports, and a destination. The hand-drawn style fits the idea of sketching a solution, but the task is still about testing a physical arrangement rather than merely making a decorative drawing.

Obstacles change the question

The source lists a varied set of later elements: saws, lasers, TNT, portals, keys, boost arrows, gravity changes, and long-shot baskets. Their presence suggests that a route may need to account for more than distance. An obstacle can make a direct line unsuitable, while a portal or a change in gravity can alter how the board should be read. The exact behavior of each element should be confirmed in its stage rather than assumed from its name.

The listed 75 stages and three tutorials offer a structured way into that vocabulary. A tutorial can introduce the basic interaction, while later boards add conditions. I do not claim a specific order or difficulty curve beyond those stated counts.

A useful pause before release

Before letting a band go, inspect whether it is holding the ball or preparing to launch it. The game instructions identify drawing, stretching, releasing, undoing, restarting, and using a hint. Those actions provide a practical cycle: make a setup, observe the result, then try again if needed. The live interface shows the exact input for mouse or touch.

Rubber Doodle makes the drawn line part of the solution. The ball, pegs, elastic bands, and cup form a small physical system that invites experimentation. Its strongest puzzle moments begin when the player stops drawing for a second, reads the available route, and chooses a line with a clear purpose.
