How to play

• Oily beads don't like water. Fold the chain so they touch each other.
• Water-loving beads are happy on the outside.
• Tap a bead to swing the rest of the chain around it, like a hinge. The small ↻ arrow on each bead shows which way it will swing. The chain can't cross itself.
• ➜ Yellow arrows show the pull between oily beads that aren't touching yet.
• Press Lock In when you're happy. The best possible fold earns ⭐⭐⭐. Stuck? 💡 Hint shows the next tap, but costs 50 points.

Every level's best fold was checked by a computer that tried every possible shape.
