Tideglass Dispatch is a small canal-routing puzzle: turn the canals so water reaches every matching dock without leaking. Its 24 fixed charts introduce branching routes, one-way locks, and two currents that cross in separate bridge lanes.
You can try a free three-chart demo from the game page. It includes a simple route, a branching route and a lock puzzle. The complete 24-chart download costs US$3 minimum. Both are desktop-browser downloads: extract the ZIP and open index.html. Compatibility details are on the page.
All charts are open from the start. There is no timer, and undo, restart and hints are free. The game has no ads, accounts, subscriptions or in-game purchases. Demo progress is separate from the full game.
