Tidele

Five short tests a day, the same for everyone, played one after another. Each scores 0 to 100 by how close you get, and your tests average into a grade. A new watch starts at midnight.

Comparing your score with everyone else's comes later.

Fog Find. A ship sails into a fog bank. When the bell rings, tap where she is.

Chart a Route. Watch the traffic, then draw your route from the dock to the gate. Everyone moves at once.

Bilge Rush. She's flooding. Trace the pipes from the flooding compartment to the pump and open the right valves before the clock runs out.

Gangway Count. People leave the ferry for a few seconds. How many got off?

Set & Drift. The current is running. Launch your boat so the water carries it into the dock. Three shots; your best counts.

Practice mode, after today's results, gives you fresh, random versions of each test. Practice scores aren't saved.

A game, not navigation training: the water, ships and lights here are simplified.
