Here are the difficulties in Dark Castle Series.
Main Article Novice
In Color Dark Castle, the novice difficulty plays differently then the other difficulties, it skips all the in between levels, from the Great Hall, and has the doors take you to the final levels, Shield 4, Fireball 4, Trouble 3, and Black Knight 3. Other changes include less Enemies, longer time between Gargoyle appearances, longest time between Boulder throws from the Rock Henchman, and worse aim for the Black Knight.
It is currently unknown how this will work in Return to Dark Castle.
Main Article Beginner
In Dark Castle it contains the least amount of enemies, the longest time between Boulder tosses from the Rock Henchman, and the longest wait between Gargoyle appearances. In addition, the Black Knight's mugs don't bounce.
Main Article Intermediate
This is the medium difficulty in the Dark Castle Series.
In Dark Castle, and Color Dark Castle, it has more enemies, and shorter times between Gargoyle appearances. (In Color Dark Castle, there is no Guard in Fireball 1 on Intermediate, where as, in the original, there was.) In addition, the Black Knight's mugs bounce once.
Main Article Advanced
This is the hardest difficulty in the Dark Castle Series.
In Dark Castle, and Color Dark Castle, it includes the shortest time between Boulder tosses from the Rock Henchman, the shortest time between Gargoyle visits, and the most enemies. In addition, the Black Knight's mugs bounce twice.
In addition, when beating the game on Advanced, there are different outcomes for each game:
- In Dark Castle, if you beat the game on Advanced, it will start you over on Advanced, except that the Black Knight's mugs will bounce an extra time and the bonus ticker will count down from a higher number to allow for increased scoring. Beating the game once more will start the game over again, except the Black Knight's mugs now bounce a fourth time and it becomes impossible to gain any more points (and thus, earn any further extra lives). Further victories against the Black Knight simply drop the player into Trouble 3 without changing anything. The number of times the Black Knight's mugs will bounce is indicated by the single-digit number in the bonus ticker in the Great Hall.
- In Color Dark Castle, if you beat the game on Advanced, the backgrounds fades out, while Prince Duncan does a dance.
