Teeter Tubes

How to play

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

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