Inkbridge: Draw Physics Puzzle

A line-drawing physics puzzle: draw with limited ink, the lines turn solid, and the ball rolls along them to the ring. Keep drawing in slow motion while it rolls. 24 pages, stars for ink saved. Free, no ads, no tracking; mouse, touch or keyboard.

A notebook page, a red ball and a gold ring. Draw a line and it dries into something solid; press Go and the ball rolls along whatever you drew. The ink pot is small, so the shortest bridge that still works earns three stars.

You are not done when the ball starts rolling. Touch the page again and time slows to a third while you draw, so you can catch a ball in mid-air or finish a bridge just ahead of it. Blue ink drops refill the pot on the pages that are too wide for the ink you start with.

• 24 pages: every one checked solvable by a bot that draws the stored solution
• Live drawing with ink time: draw while the ball rolls, in slow motion
• Ink drops: refill the pot mid-roll
• Thorns, glass, springs and gates: new elements arrive one at a time
• Stars for ink saved: the ink bar marks the two- and three-star lines
• Mouse, touch or keyboard: the keyboard pen draws while Space is held
