Pencilogic

Draw a line and it falls, rolls and pushes things like the real thing. Build bridges, chutes, walls and counterweights across 24 levels on squared paper.

Every level is a short puzzle on squared paper: make the balls touch, get the ball into the basket, knock the box off the page or keep it from falling. You draw the solution with your finger.

When you lift your finger, the line becomes a real object: it falls, rolls, tips over and pushes others. A dot turns into a small ball. A bridge across a gap, a chute into the basket, a roof against falling crates, a weight on a seesaw — every level has more than one solution.

Three stars for solving with the fewest shapes, and a hint shows one solution when you are stuck. Progress is saved in the browser, and the game runs on phones and computers with nothing to install.

How to play

  • Draw with your finger or the mouse — once you lift your finger, the line obeys physics.
  • The world starts moving after your first line; you can keep drawing afterwards. Lines cannot pass through objects or red hatched areas.
  • At the bottom: undo the last line, hint, restart and menu.
