Tractor Spheres

A physics puzzle: a small black ball sits in a maze and you have a few tractor spheres to place. Press and hold to grow a sphere (bigger means stronger pull), then start the level and watch the ball get dragged through the gaps and bounce off the walls into the spinning goal before the timer runs out. 25 levels with a score summary for time, unused spheres and extra tries.

How to play

Mouse or touch: press and hold on a free spot to place a sphere and keep holding to make it bigger (it stops growing at walls, other spheres and the goal), then press Start Level. The round button at the top right removes your spheres, Retry restarts the attempt. Keys: M music on/off, S sounds on/off.

Click the game first so it gets the keyboard. P or Esc pauses; the speaker button in the corner mutes the sound.
