This variation is for both NTSC and PAL as there is no difference between the two on the Intellivision Video Game Console.

Excessive leeching is not permitted. 

The game-play is extremely slow on the first few levels so it may take some time to clear the first few screens. 

The player must be advancing through the screens in a reasonable manner. If a player stays at the first few screens for an unreasonable amount of time in order to accumulate treasures (and points), the player's score will be invalid. 

If a player hangs around on later screens after killing-off two enemies in order to accumulate points while there is only one enemy left on the screen, it is also considered leeching. Give the player the benefit of the doubt with respect to leeching.

This is the Quest for the Golden Knight. What started in Medieval Times, the search for the Golden Knight still exists and persists in modern day in the Twin Galaxies Kingdom. For this Quest, each of the first SIX screens provides a 10 Minute deadline for your Knight to clear the screen. Starting on screen SEVEN (the third Dragon screen) and all of the screens beyond, your Knight is provided with a 15 Minute deadline to clear each screen. To be clear to those from Yonder Lands: You have a 10 Minute deadline to clear each of the first SIX screens. From screen SEVEN and beyond, you have 15 Minutes to clear each screen. The timer starts on each screen as soon as the frozen graphic disappears and your game maze appears, allowing your Knight to move. To avoid controversy, you have ONE second of grace period to give the benefit of the doubt to the player if/when the Adjudicators from the Kingdom of Twin Galaxies must use fractions of seconds to determine whether you made it out of the screen. If a Knight is clearly a full second late (or more), that Knight's Quest ends on the spot. The competing Knight must immediately turn in his sword. The timer stops on each screen at the moment of the last kill when the Medieval Celebration Music starts playing. Collect as many Magical Items, Bags of Gold and Extra Knights as your heart desires but be cautious of the deadline; for the scent of greed for treasure has retired many a Knight in this Quest. Your points awarded for this scoreboard equals your point total on the screen when you lose your last Knight.... Unless your 10 Minute or 15 Minute deadline expires on ANY screen during your Quest. In that case, your points are equal to your point total at the exact moment of the deadline; be it 10 Minutes or 15 Minutes. Many will attempt this Quest but there are only three titles bestowed upon the most courageous of Knights in the Kingdom. Third place on this board is bestowed Bronze Knight. Second place on this board is bestowed Silver Knight. First place is crowned the Golden Knight.
