The game is aimed at gradually scoring as many points as possible. The points are awarded for collection of various bonuses and diamonds as well as for destruction of monsters. Digger's joy of scoring is endangered by Monsters who lose no effort to eat Digger. Of primary importance are bonuses. When 'eaten' by Digger they can miraculously reshape the game by changing the parameters of playing in general or the parameters of some of the game's characters. Digger is on a truck that goes up and through many different levels. The only condition of passing on to the next level is to collect all the diamonds on the current level unless he collects a bonus that may sharply change the course of the game. To fight against the monsters, Digger can use a grenade-gun and, first of all, his own cunning and quick wits.
