Nessie

In Nessie you are part of an expedition into the dark waters of Loch Ness, searching for ancient treasures while trying to find the mysterious Nessie. But watch out! You'll have to know when to back off, because if you load your boat with too much treasure you may sink, losing everything and... scaring Nessie away! Whoever has better sighted Nessie, and collected the most treasure, will win the game. —description from the publisher
