MathCraft: Path Puzzle
The world shattered into floating islands and the old transport network stopped working. You are the engineer rebuilding it: laying directed rails between stations A, B and C and making sure the train reaches its goal.
How to play
Tap a source station, then a target station — a rail appears between them. The mouse works the same way, and a finger drag builds a route in one motion. Tap the same station twice to create an identity path: from A to A, without moving. Once the network is ready, Launch the flow sends the train along the valid composed path.
What bites
Two rails join only when the end of the first matches the start of the second. If a path ends in B and the next starts in D, the game plainly explains the incompatible joint and never punishes curiosity. You act first, then learn the name: composition. Later come the empty path, branching, and a functor gate that carries the whole network into a new world while preserving its links.
Eight levels
From First Light to the finale The Network Awakens. A single rail A→B, then the B→C bridge, the composed A→B→C path, the search for an incompatible joint, the identity path, a fork into two branches, the gate of worlds, and a final network that uses every rule at once.
Who it's for
For anyone who likes figuring out why two things will not connect and enjoys the moment a diagram finally comes alive. Terms arrive after the action; no formulas are needed before you start. Playable with mouse and touch, on a phone or a computer.
