Marble Machine

How to play

1. Tap the pink marble at the start. Follow it down the track and see what happens at the end.
2. Tap one of the three pieces to change it: a left or right ramp, a bell, wheel, tunnel or seesaw, then a flower, bear or duck.
3. Roll again to try your new machine. Hold the moving marble to stop it, guide it along the track, then let go to keep rolling. A simple tap at the start works too.

Playing with a keyboard? Press Space or 1 to roll. Press 2 to change the ramp, 3 for the middle piece and 4 for the finish. Arrow keys move between the four objects; Enter or Space activates the focused object. Tab works too.

A little chain reaction

The ramp changes the route. The marble rings the bell at contact, turns the wheel as it travels around it, hides briefly in the tunnel, or tips the seesaw before rolling on. At the end, the flower opens, Bear’s hat pops up or the duck sings a little note. You can enjoy each surprise with sound off.

There are twenty-four combinations to explore. The pieces connect automatically, so there is no missing link or wrong place to drop a part. Guiding the marble is optional: it stays on its track, even if a little hand wanders. Changing a piece while the marble is moving brings it back to the start, ready to try the new route.

A little help for parents

This is free building, with a working machine from the start. There are no difficulty levels, scores, countdowns or rounds to finish.

Hold “End” for two seconds to see your machine, save its picture, or share a link to these exact three pieces. A shared link opens this page; the recipient chooses when to play. Choose “Continue building” to return to it. The pieces and the marble’s journey stay when you pause or turn the screen.

Saving a picture is also available in Parents: hold “Parents” for two seconds, or type parent. Reset the three pieces, or change the sound, background and motion. Reduce motion shows the marble at clear steps along the circuit, without spinning. When held, the marble still follows the hand directly.

The live journey stays only in this open game. A shared link restores its three pieces at the start; it does not save the journey. Saving an image downloads a PNG picture to your device; nothing is uploaded or saved to an account. Ages are a guide. Explore together and take a break whenever you like.
