Node Untangle

Node Untangle is a portrait graph puzzle set inside a handcrafted midnight observatory. Drag connected glass nodes around each star chart while every signal line updates live. Coral dashed lines and crossing sparks reveal the knots; settle the graph into a clean cyan constellation before the authored move budget runs out.

Fifteen original charts grow from a four-node crossing to dense planar lattices with loops, bridges, and tempting local arrangements. Level entry, retry, and replay are always free. Record your best move count, unlock the next observatory deck, and spend optional coins on a ghost destination hint that never moves a node for you. Clearly labeled rewarded AD controls can grant a small coin pack or one bounded three-move revive only after a successful reward callback.
