Big Dig is a small box Roll and Write. Well, it is technically not a roll and write since there are no dice to roll. I've been trying to come up with a witty reworking of the genre and the best I can think of is “Reveal and Write” since you are selecting Tetris shapes from a tableau of cards to use on your map on your turn. All the shapes are four and five cube configurations that you use to “Dig” out that shape. The objectives vary from game to game, with a set of cards determining which three objectives you are required to do to win each game. Essentially, they all break down to Connect X to Y or dig up/dig out all of type Z.
