About This Game

Welcome to the Wobbliest Lab Ever

Melon Lab is an open-ended physics sandbox where you invent silly machines and watch what happens. The lab is stocked with original melon characters and squishy test dummies who volunteer for every experiment — and who always pop back with dizzy cartoon stars, ready for the next test.

There is no single way to play. Build a towering stack of blocks, hook a dummy to a spring, line up a row of launchers, or create a chain reaction that topples the whole scene like dominoes. It is a digital junk-drawer of parts, and you are the inventor in charge.

Your Toy Box of Parts

The spawn catalog is packed with things to try, and every part follows real-feeling physics: gravity, weight, bounciness, friction, and breakable joints.

  • Blocks, ramps, wheels, ropes, joints, and springs
  • Vehicles, launchers, and harmless popper props
  • Melon characters, test dummies, and decorations
  • Tools to drag, rotate, duplicate, freeze, delete, or clear everything
  • An undo button that steps back through your last 10 moves

What You Do

  1. 1Open the spawn catalog and pick parts: blocks, wheels, ropes, launchers, and more
  2. 2Drag parts into the scene, then rotate, duplicate, or freeze them
  3. 3Press play and watch gravity, springs, and collisions bring your build to life
  4. 4Tweak and rebuild toward a bigger, sillier chain reaction
  5. 5Take on an experiment contract or save your scene for next time

Controls

  • Tap the catalog to choose a part, then tap or drag to place it
  • Drag parts with one finger; twist the round handle to rotate
  • Tap the toolbar buttons to duplicate, freeze, delete, or clear
  • Tap the undo arrow to step back through your last 10 actions

Tips for Players

Freeze the heavy base blocks before pressing play so your tower does not slide away.

Test small first: a two-part launcher teaches you more than a fifty-part machine.

Ropes and loose joints wobble; locked joints stay stiff. Mix them to control the chaos.

Stuck on a contract? Move the target closer while you test, then slide it back.

Save a working scene before you experiment wildly — you get three save slots.

Accessibility note

Melon Lab plays entirely with mouse or touch — every tool has an on-screen button and the keyboard is never required. Pause freezes the action at any time. Physics scenes can become busy and fast-moving, which some players find hard to follow; if free-form building feels too open, try Bridge Doodle Rally, a creative game that gives one clear building goal per level.

Questions & Answers

No. Dummies and melons show silly cartoon reactions — dizzy stars and wobbles — and always reset completely intact. There is no gore and nothing realistic.
