Build a dropper idea jar that fires random game ideas, then test its luck.

Stuck for ideas? Build a machine that picks your next game for you… and decide how much luck you'll trust.

What you’ll build

Build a giant glass idea jar around a dropper and load it with items that each stand for a game idea. Press it again and again, tally what comes out, then rig the odds for your favourite and let the machine choose your next game.

Finish line: Your idea jar works, you have a fair tally and a rigged one, and the machine has picked your next game.

Bonus challenge: Build a second jar for twists (backwards, underwater, in the dark…). With 9 games and 9 twists, how many combos can the machines make?

You’ll need

  • A dropper
  • A button
  • 9 different stackable items
  • Glass
  • Signs

You choose

  • My machine's name (The Oracle, Brain Blender…)
  • Its disguise: a giant jar, a wizard's cauldron or
  • The idea I secretly hope it picks

Stuck?

  • Nothing comes out? Make sure the dropper's front faces out of the jar and the button is stuck on the dropper itself.
  • Use full stacks of items that stack to 64, so a slot never runs empty and changes the odds.
  • Results look lopsided after a few presses? That's normal for small runs. Keep pressing and watch them even out.
