Is the arcade puzzle game game created for the Commodore 64 home micro back in the mid 80's and was released by FirstStar sofware. The central character Rockford had to collect a certain amount of diamonds to escape each cave and proceed onto the next level - it even made it into the Arcades using the Amiga hardware if I remember correctly.

It IS NOT to be confused with Balderdash to mean "nonsense; something stupid or untrue".. you stupid mofo.
Boulderdash remains a classic examples great gameplay and of the Commodore 64s supremacy.

Boulder Dash is actually bird shit, like when a bird hops onto some rocks and drops a shit on them- shit that is splashed onto a boulder of rock,especially if dropped from a height.
