Necklace

Squares & primes · 30 levels

Thread the beads so every touching pair makes magic.

How to play

1. Tap a bead in the tray, then an empty spot on the string. Tap a threaded bead to take it back.
2. Two touching beads make a link: their sum. A link glows gold when its sum is one of the magic numbers shown.
3. Thread every bead so the whole ring glows. The gold-ringed clasp bead is fixed.

Start with the pickiest bead: the one that has only two possible partners. Its neighbours are decided for you.
