Tide Clock Harbour
A mobile puzzle where you drag to scrub through a real lunar-driven tide curve and schedule boat movements around a harbour with a drying entrance. Twelve tasks — get boats in and out, cross the bar, dry out for repairs and refloat — must be completed while the harbour scene itself rises and falls with the water. A moon-phase dial ties the tidal range to the lunar cycle, landing the connection between spring/neap tides and the moon. Finish with a shareable result card of your tide chart and completed tasks.
