Front Runner, 1984
The objective of Boulder Dash is to search throughout each CAVE and collect as many Jewels in as short a time as possible. Once the indicated amount of Jewels have been collected, the door to the mysterious escape tunnel is revealed and you go to the next level. Strategy and planning will help you master the "physics" of Boulder Dash. Boulders drop predictably enough, but you and Rockford also have to block growing Amoebas, transform Butterflies, outmanoeuvre Fireflies, and overcome other numerous obstacles.
