The 7 dwarfs' treasure

Your teamspirit will lead you to a hidden treasure

Once upon a time, 7 very canny dwarfs discovered a treasure deep inside a mine. They didn’t want to announce it to the world, but decided to keep it all to themselves. They promptly hid it again in a different spot, but fate prevented them from ever retrieving it, or revealing its whereabouts.

Some time ago, a group of novice history buffs discovered a mysterious map in the mine…
