The game is one of the earliest adventure games to have a demo mode that shows you a demonstration of game play. The game has no "continues", and only the "Adam" version of the game supports saving. If the player incurs too much damage, they lose a life, and losing all lives ends the game, though extra lives may also be obtained as well. There are also many traps or enemies present for the player to either fight or evade. You also have a map in the bottom left corner, that can help prevent you from being lost in the castle dungeons. Various items may also be obtained in the game, such as a pistol used for attacking or a "hook" that can be used to cross gaps.

The game has four difficulty levels: beginner, intermediate, advanced, and expert. The map and routes change every time a new game is started. Each castle has multiple rooms, traps and floors. The player's main goal is to move the character through the various castles to ultimately arrive at the main castle fortress on the right side of the map. The game starts on a world map, which contains 22 castles. The plot of Alcazar is to get to the main castle "Alcazar", by going through multiple enemy castles, to retrieve the stolen Crown.
