Teeter Tubes

Available now

Sort paper marbles by colour on cardboard balance scales. Every move shifts the weight, and a beam that leans too far will tip.

Teeter Tubes is a colour-sorting puzzle made of paper and cardboard, where every tube hangs from a balance scale. Move a marble and the beam swings. Let one side get too heavy and it tips, so you have to keep the weight even while you sort.

The pencilled dial above each scale shows how much room you have. Stitched double discs count as two, grey marbles with a folded corner hide their colour until they reach the top, and levers make one side pull twice as hard.

There are 200 levels in eight worlds, a new daily puzzle every day, and a par for every level: the fewest moves it can be solved in. Undo is unlimited, there's a hint when you're stuck, and every marble carries a shape mark for colour-blind players. It plays on phones, tablets and computers, and saves your progress in your browser.

How to play

  1. Tap or click a tube to pick up its top marble, then tap another tube to drop it there.
  2. A marble can go into an empty tube or onto a marble of the same colour.
  3. Keep each beam inside the notches on its dial, or it tips and the move springs back.
  4. Keyboard: Z or U to undo, R to restart, H for a hint, Esc for settings.

  • A red marble lifted out of its tube while the scale beside it leans under the shifted weight.
  • A solved level: confetti, three stars and a Spot on card showing 9 moves against a par of 9.
