The game, "Underwater Time Machine," is about estimating time accurately on a submarine journey to avoid being crushed at sea level due to torpedo attacks from below and explosions. Two routes are chosen with stopwatch accuracy measurement after hiding numbers in the map display for safety reasons against potential kidnappings by villains seeking underwater treasure under fake identities or other criminal activities, but they also provide an alternative approach if you want a less adventurous experience of measuring time accurately on short trips to keep children focused during longer wait times.
