How to play

• Nodes are scattered across the board, connected by lines. When two lines cross, they glow red.

• Your goal: zero crossings.

• Tap any node to select it. Tap another to swap their positions. That's the whole mechanic!

• The question is how few swaps it takes you to find it. Good luck!
