Paper Ball is a free online line-drawing puzzle game where you draw custom paths to roll a paper ball straight into a trash can. Using just your finger or mouse, you sketch out routes in real time, letting physics do the rest. Every line you draw matters, and getting the ball to drop perfectly into the bin is genuinely satisfying.

Each level throws new obstacles at you — walls, barriers, and tricky angles that force you to think before you draw. There's no single correct solution, which means your approach will be completely different from someone else's. Short, sharp lines work for tight spaces, while long sweeping curves help carry momentum across wider gaps. The physics feel responsive and natural, so when a run goes wrong, you can immediately see why and adjust your path. Levels ramp up gradually, keeping the challenge fair without ever feeling cheap.

Paper Ball is a great pick for fans of brain teasers, casual puzzle games, and physics-based challenges. If you enjoy games like line rider, ball drop puzzles, or drawing games that test spatial thinking, this one slots right in. It's also genuinely relaxing to play during a break — there's no timer pressure, just creative problem-solving at your own pace.
