Read the current and cast nets at three fishing grounds. Shallow fish earn 2 points and deep fish 4. With 12 rope and at most nine casts, reach targets of 30, 33, and 36 points.
A/D selects a location, W/S switches between FINE NET and WIDE NET, and RETURN casts. A fine net covers one column for 1 rope; a wide net covers two adjacent columns for 2 rope. Your selected net type remains selected for the next cast.
Directions work on the keyboard or pad; the pad button also acts as RETURN. SPACE opens confirmation to restart this stage. NO is selected initially. Choose with A/D, confirm with RETURN, or cancel with SPACE. Play pauses during confirmation. CTRL+C returns to BASIC.
Waves, sinking nets, the two drifting schools, and hauling in a catch are shown separately. Casting, catching, and missing have distinct sounds. Wait for the animation to finish before pressing again.
TIDE shows direction and strength. Before the catch is checked, shallow fish drift by that amount and deep fish by twice as much. FISH is your score; CASTS is casts remaining. Save rope for opportunities to catch both schools with a wide net.
