DunkLine

About This Game

DunkLine reinvents basketball puzzles by putting a pen in your hand instead of a ball. Draw lines and ramps on the screen to guide a basketball into the hoop using gravity and momentum. Each level presents a unique arrangement of hoops, walls, and obstacles, and your drawn lines become the physical surfaces the ball rolls and bounces along. The creative freedom to design your own solution makes every level feel like a personal engineering challenge. Some solutions require elegant curves while others demand precise angular platforms — there is rarely just one right answer. With its blend of physics simulation and creative drawing, this free browser game appeals equally to puzzle lovers and aspiring engineers.

How to Play DunkLine

Each level shows a basketball and one or more hoops positioned around the screen. Your task is to draw lines on the screen that will guide the ball into the hoop when physics takes over. Before drawing, study the positions of the ball and hoop to plan your approach. Click or tap and drag to draw lines anywhere on the playing field. Your drawn lines become solid physical surfaces — the ball will roll along them, bounce off them, and slide down slopes you create. Once you finish drawing, tap the play button to release the ball and watch physics take effect. The ball responds to gravity immediately, so lines must be positioned to catch the ball and direct it toward the hoop. Angled lines create ramps that accelerate the ball in specific directions. Curved lines act as bowls or funnels that redirect momentum. Each level limits the total amount of ink you can use, shown by a meter at the top. This prevents brute-force solutions and forces creative efficiency. If the ball misses the hoop, hit retry to erase your lines and try a new approach. Some levels have multiple hoops that must be dunked in sequence — the ball needs enough momentum from your ramps to reach each one. Obstacles like spikes and barriers destroy the ball on contact, so route your lines carefully around them. Experiment freely — the beauty of DunkLine is that unconventional solutions often work best.

Tips & Tricks for DunkLine

• Angle your ramps steeper for more speed and gentler for more control over the ball's direction
• Draw funnel shapes near the hoop to catch the ball even if your aim is slightly off
• Use as little ink as possible on early sections to save more for tricky final stretches
• Create small bumper walls near hazards to prevent the ball from rolling into spikes
• Test your solution mentally before drawing — visualize how gravity will move the ball along each line
