How to play Draw the Bridge
Draw the Bridge is a free physics drawing puzzle where your pen is the only tool you have. A little red car waits on the left, a green flag waves on the right, and somewhere in between there is a gap, a wall, a pit or a steep cliff. Your job is to draw a bridge that gets the car safely across. The twist: your drawing is not just a picture. As soon as you press Go, every line becomes a solid beam with real weight that drops, tilts and settles under gravity before the car drives onto it.
- Study the level. Find the gap, wall or pit standing between the car and the flag.
- Draw one or more lines with your mouse or finger. While you draw, lines stay frozen exactly where you put them.
- Watch the ink bar at the top. When it runs out you cannot draw any more, so plan before you scribble.
- Press Go! Your lines fall and come to rest, then the car starts driving to the right.
- Get the car past the flag to win. If it falls into the water or gets stuck, tap Fix my bridge to adjust your drawing, or restart the level.
Tips for building a bridge that holds
- Rest both ends on solid ground. A line floating in mid-air simply drops into the water. Start your bridge on top of one cliff and finish it on top of the next, overlapping each edge by about a car length.
- Draw just above the surface. If your line starts slightly above the ground, it only drops a tiny distance and the car rolls straight onto it. A bridge drawn high in the air falls and may land crooked.
- Keep slopes gentle. The car has a small engine. Long, gentle ramps work far better than short, steep ones, and a ramp that is too steep makes the wheels spin and the car slide backwards.
- Use pillars and platforms. A post in the middle of a huge gap or a floating platform is a free support: rest your lines on it and you can cross gaps far wider than your ink would otherwise allow.
- Glue lines together. Lines that touch are welded when you press Go, so two short strokes meeting on a pillar behave like one strong beam. Use this to build V-shaped valleys and staircases.
- Straight lines save ink. Wobbly lines are longer than they look. Draw smooth, confident strokes and you will earn three stars much more often.
- Walls need a ramp on both sides. To get over a wall, draw an upward ramp, go over the top and come back down again. A tent shape resting on the wall is very stable.
What you will find in the levels
The levels start gently with a short gap that needs only a few metres of ink. Soon the bridges have to go downhill and uphill to reach landings at different heights, then you meet levels with two separate gaps, a lonely pillar in the middle of a huge chasm and a floating platform you can use as a stepping stone. Later levels mix everything together: a deep pit with steep walls that traps the car, a brick wall in the middle of flat ground, a steep climb to a high cliff, a level with barely enough ink for a single beam, and a final long climb supported by two thin posts. Every level can be solved in more than one way, so if your first idea does not work, try a completely different shape.
Why bridge drawing games are so satisfying
Bridge building puzzles are a classic of physics gaming, and the drawing version strips them back to the most natural tool there is: a pen. There are no menus of girders or bolts. You see the problem, draw a solution and find out within seconds whether your idea works. A failed attempt is part of the fun, because watching a bridge tip into the water teaches you something about balance, support and slope that you can use straight away. The puzzles quietly train spatial reasoning and planning, and the ink limit rewards elegant, efficient solutions rather than brute force. That makes Draw the Bridge a good choice for a quick break, and a fun way for kids to explore how real bridges are held up by what is underneath them.

Draw the Bridge FAQ
How do you play Draw the Bridge?
Draw one or more lines with your mouse or finger to build a bridge or ramp, then press Go! Your lines drop under gravity and the car starts driving. Get the car past the green flag to win the level.
Why did my bridge fall down?
Every line you draw is a real, solid object. When you press Go it falls until it lands on something. A bridge only holds if both ends rest on cliffs, pillars or platforms, so always start and finish your line on solid ground.
How are stars awarded?
Stars depend on how much of the ink bar you use. Finish with half the ink or less for three stars, up to 80% for two stars, and any successful crossing earns one star.
Can I draw more than one line?
Yes. Draw as many lines as your ink allows. Lines that touch each other are glued together when you press Go, so you can build supports, trusses and ramps out of several strokes. Use the ↶ button to undo the last line.
Does Draw the Bridge work on phones and tablets?
Yes. Draw with your finger on any touch screen, or with a mouse or trackpad on a computer. It runs in the browser with nothing to download or install.
Is my progress saved?
Yes. Unlocked levels and your best stars are saved in your browser on this device, so you can come back and improve your score any time.
