The rules
- Move the top bead from one tube to another until each tube holds only one letter.
- A bead can only go into an empty tube or onto the same letter, and only if there is room.
- All tubes hold the same number of beads, and each letter has just enough beads to fill 1 tube.
- You can also move beads out of a full tube.
- Any moves that finish the puzzle count; you do not need the fewest.
A worked example
Each tube holds 2 beads. Read these stacks from bottom to top: A B / B A / empty. Move B from tube 1 to tube 3. Next, move A from tube 2 to tube 1. Then move B from tube 2 to tube 3. You finish with A A / empty / B B.
You cannot start with tube 1 to tube 2: their top letters differ.
Playing it in Quirk
Tap a tube to pick up its top bead, then tap the tube where it should go. Tap the same tube again to put it back.
Notes are reminders and do not limit your moves.
Tip: Keep an empty tube for beads you need to move aside.
