one fresh graph puzzle each day for a steady planarity challenge
daily graph puzzle
planarity
a daily planarity puzzle game about untangling planar graphs until no edges cross
1 crossings
untangle the graph
graph
vertices and edges form the puzzle instead of tiles letters or numbers
planar
the goal is a planar graph drawing where connected edges do not cross

learn the idea
planarity comes from graph theory. if a graph can be drawn without edge crossings it is planar. the puzzle turns that mathematical property into a daily graph game.
daily planarity puzzle
planarity gives you a daily graph puzzle built around the same simple goal each time. untangle the graph until every crossing disappears.
graph puzzle game
instead of matching tiles or letters, the puzzle uses vertices and edges. each move changes the drawing while the graph itself stays the same.
planar graph puzzle
a solved board is a planar graph drawing. connected edges can meet at shared nodes, but no unrelated edges should cross.
