You are an adventurous archaeologist, digging into the earth for artifacts, treasure, and other goodies. Every day requires a new plan to be efficient, so you and the other archaeologists on the site will be competing to see whose is the most efficient!
Each turn in Big Dig, you draft a card from the center that shows you the shape in which you must dig (by crossing out squares on your personal dry-erase board). You must touch either the top of the digging area or a previously dug area, and you can't go through certain areas (though you may forgo regular digs to blow up stones that are in your way). When the cards in the center run out, everyone returns their cards to the center and flips them over so that different digging shapes are now available.
Every game, three random goals are dealt out, and the first person to accomplish all of them wins!
There are a variety of goals that can be in play, the player boards are double-sided (everyone plays with the same side in any given game), and which side of the digging cards is face-up to start is different, so every play is different!
