Brain On Line
Solve challenging physics puzzles by drawing shapes and lines. Each level has multiple solutions, encouraging creativity and a deep understanding of gravity and motion to achieve the goal and earn stars.
About This Game
Brain On Line is a physics-based puzzle that emphasizes "Free-Form Solution Logic." The core is "Entity Materialization"—lines or shapes drawn on the screen instantly become physical objects subject to gravity, collision, and friction. It highlights "Torque Balance" and "Leverage Principles," where players must create physical structures to move a ball to a target, acting as a "Logic Sandbox."
How to Play
Draw any line with your finger. Once completed, the line falls or remains as a fixed structure depending on the level rules. The gameplay is "Goal-Oriented": guide the ball to a designated zone. Interaction involves "Static-Dynamic Switching"—drawing a ramp for sliding or a heavy weight to drop and provide kinetic impact to the ball.
Tips & Tricks
High scores (3-star ratings) depend on "Line Length" and "Execution Time." The shorter the line (less "Brain Power" consumed), the higher the score. The pro secret is "Minimalism"—using a single dot or arc to trigger a chain of momentum rather than building complex bridges. Mastering "Fulcrum Logic" to flip heavy objects is the key to top-tier play.
Frequently Asked Questions
Q: Why do my lines disappear?
A: Some levels feature "No-Draw Zones" or line-life limits. You must complete the physical conduction within the available space and time.
Q: Can I undo a mistake?
A: Yes, the reset or undo button allows you to quickly refine your physical model and test different mechanical theories for the solution.
