Classic Prince Of Persia mini-game:
After getting the second sword that can break walls (approximately one third of the way through the game after the "Above the Bath's" area), you will reach a large location where you must pass through a door with Farah and activate a lever to open another door to a hallway filled with scarabs. There are three positions to this switch (open door into room, open door to hallway with scarabs, and open secret door to the classic Prince Of Persia). The switch is located at the end of the room, near the save point and near a large piece of rubble. There is a wall opposite to that lever that appears to be unbreakable, and does not look like other wall areas that can be manipulated. When you hit this secret area on the wall, it will not spark as expected. After setting the switch to unlock the door to the mini-game, keep hitting the non-sparking section of wall until it breaks. A message will appear to state that the classic Prince Of Persia has now been unlocked.

Alternately, successfully complete the game.

Classic Prince Of Persia: Level passwords:

 

Hint: A Prisoner Seeking An Escape: Hangman:
When you reach the bottom of the chamber in the A Prisoner Seeking An Escape level, kill all the sand creatures and then enter the cell to the left when looking at the save point. In the left corner of the cell is a little joke on the wall. Take a closer look in first person view at the drawings you find there. Obviously the prisoners where playing hangman here.

Hint: Baths: Magic Fountain:
After earning yourself the second sword which can break the walls, gain access to the secret corridor. Stop halfway through the corridor and on the right wall should be a wall with a crack that someone has hastily concealed. Break the wall to find another Magic Fountain.

Hint: Courtyard: Magic Fountain:
After completing the trap corridor where you had to race to the slowly closing door, you will battle some Sand Monsters in the courtyard. After this has been successfully done, climb up the courtyard. When you are in the section where you have to climb up the ladder which appears above the spikes, continue until you find a Sand Cloud. Near the sand cloud is a hole in the wall. Climb up the rubble and run among the wall to grab on the ledge. Go through the hole to find yourself in a mystery area. Keep walking on the bridges until you reach a fountain. Drinking from this fountain will raise your life bar.

Hint: Daybreak: Avoid battles:
When the Prince and Farah attempt to cross the drawbridge you have lowered, many sand creatures will appear to battle you. Just run past them on the left and into the open doorway with the switch inside. They will not follow, and you wll not have to fight them.
 

Hint: Defense system puzzle:
When entering the room with the defense system in it, follow these steps to complete the puzzle.
 

Hint: Tomb doors puzzle:
Near the end of the game, you are in a tomb with infinite doors. You have to find the correct series of doors to progress. Go to the landscape view. Always start at the door with the face above it and go clockwise. The order is:

After you have successfully done this you will be taken to the second level of this room. It is almost the same, just with more doors. The order is:

An intermission sequence will then follow.

In the circular room you find in the tomb, there are doors that you must enter in the correct order, or be teleported back to the start. One way to make sure you go through the correct door is to listen carefully. When you are in front of the next door that you need to enter, you will hear the sound of trickling water. This indicates that you are standing in front of the correct door. Repeat this until you have solved the maze.
 

When you are almost at the end of the game, you will be trapped in a room with a lot of doors. Every time you go in one, you end up back where you started. An easy way to find the correct doors is to run by the doors until you hear a splash of water. As soon as you do, stop and go into the door. Repeat this three more times and you will be at the second set of doors. Do the same thing four times and you will pass the level.

Hint: Underground Reservoir: Swinging on ropes:
When you are swinging on the ropes (by holding R1) and you are at the end of a swing and close to the object that you want to swing to, press X, then release R. When you hit the rope, press X. Note: You should make it most of the time.

Hint: Easy fights:
Use the dagger to stab the enemy so that he becomes frozen. Then, hit him once with your sword so that he floats in the air. When he lands, he will be lying on the ground. Stab him with the dagger to take his sand.
 

When you encounter an enemy, press X to vault over him, and while in the air press Square then Triangle to kill him. Note: This works on most, but not all, enemies.

Hint: Repeatedly drink:
Hold R1 when drinking from a fountain or pond and you you will drink repeatedly.

Hint: Farah's attitude:
When near Princess Farah, switch to first person view and look at her for a long time. At the beginning of the game, she will soon tell you to stop staring at her. Later in the game, she will tell you that your eyes are green and you can look at her if you want.
