An evil magician has stolen the Enchanted Chalice and has hidden it somewhere in the Kingdom. The object of the game is to rescue the Enchanted Chalice and place it inside the Golden Castle where it belongs.

This is no easy task, as the Evil Magician has created three Dragons to hinder you in your quest for the Golden Chalice. There is Yorgle, the Yellow Dragon, who is just plain mean; there is Grundle, the Green Dragon, who is mean and ferocious; and there is Rhindle, the Red Dragon, who is the most ferocious of all. Rhindle is also the fastest Dragon and is the most difficult to outmaneuver.

There are three castles in the Kingdom: the White Castle, the Black Castle, and the Golden Castle. Each castle has a Gate over the entrance. The Gate can be opened with the corresponding colored Key. Inside each Castle are rooms (or dungeons), depending at which Skill Level you are playing).

The Castles are separated by rooms, pathways and labyrinths. Common to all the Skill Levels is the Blue Labyrinth through which you must find your way to the Black Castle.

You can move in any of eight directions with the joystick. To move from one area to an adjacent area, move "off" the screen through one of the openings, the adjacent area will be shown on your screen.

Scattered throughout the Kingdom are certain objects to help you in your search for the Enchanted Chalice. To pick up an object, all that is necessary is to touch it. You will hear a sound that will notify you that you have the object in tow. To drop the object, press the red controller button. You will hear a different sound that will tell you that the object has been released.

To open any Castle, touch the Gate with the corresponding colored key. The Gate will slide open and you can enter the Castle by moving upward through the Gate. If you are leaving the Castle, it is advisable to push the Key out first or you may inadvertently close the Castle Gate behind you.

While the Evil Magician has created many hazards to slow you in your quest to rescue the Enchanted Chalice, there is some Good Magic on your side:

SWORD: You can use this to slay the Dragons. To do this, you must touch him with it.

BRIDGE: This can be used to pass over the walls of any portion of the Kingdom. The Bridge CANNOT be used to pass through any barrier into the next portion, nor can it be used to move from right to left or left to right over a barrier or wall. It also CANNOT be used to get past a locked Castle Gate.

GOLD KEY: Yorgle, the Yellow Dragon, is afraid of the Gold Key and will run from it. He will also stay away from whatever room or area of the Kingdom in which it may be.

MAGNET: To remove objects that are stuck in a wall and out of reach, there is a Magnet that affects all inanimate objects, including the Bridge. The Magnet can also be used to move objects in an adjacent part of the kingdom by putting it in front of you before entering that part of the Kingdom.

The Evil Magician has cast a spell to make it difficult for you to succeed in rescuing the Enchanted Chalice. Not only do the Dragons rally around and try to stop you from getting the Enchanted Chalice, they guard other objects in the Kingdom:

GRUNDLE, the Green Dragon, guards the Magnet, the Bridge, and the Black Key.

RHINDLE, the Red Dragon, guards the White Key.

When not guarding the Enchanted Chalice, YORKLE, the Yellow Dragon, roams freely about the Kingdom. Sometimes he will assist Grundle or Rhindle in guarding whatever it may be that they are guarding.

Some Magic can be good or bad, depending on the situation:

You can catch the BLACK BAT and carry it and whatever the Black Bat may be carrying. However, sometimes the Black Bat will escape (usually at the most inopportune times).

If there are four or more objects (including the Castle Gates) in your area of the Kingdom, your magic may or may not work. Sometimes you can slay a Dragon, sometimes you can't. However, it is easier to avoid being swallowed by a Dragon.

Adventure contains one of the earliest examples of a gaming 'Easter Egg', a term coined for this game. Can you find it?
