WELCOME TO THE FREE DEMO

A route for every letter.

Rotate the movable canals to connect source 1 to every matching dock. Click Release the tide whenever you want to check. A failed check costs nothing.

  1. Seal the wet route. Every opening reached by water needs a connecting canal. Dry spares may stay unused.
  2. Feed every branch. A junction sends water down each arm.
  3. Follow the arrows. One-way locks only accept water at the tail and release it at the arrowhead.

Undo and restart are unlimited. Hint aligns one canal toward an authored solution; your demo atlas still counts a guided delivery. All three demo charts can be played from the start. The full game contains 24 charts.

Three letters, safely home.

A turn around the headland. Two docks sharing a current. An arrow pointing the way. Thank you for visiting the Canal Post.

This completes the free demo. The full game has 24 authored charts, with longer routes, more branches, one-way locks, and separate crossing tides.

You can keep exploring these three charts. There is no timer or purchase requirement, and your demo progress stays separate.
