Upon entering the tower, proceed forward toward the chair. Sit inside the chain and push the button to receive a message from Saavedro. After the message concludes, look up and pull the lever to raise the chair to the top of the tower.
 You must connect the tracks, as represented on the console, to complete the Amateria age. |
When the chair rises to the top of the tower, you'll spot four colored buttons. Each button corresponds to one of the Amateria puzzles (one you haven't completed just yet). To discover which color represents which puzzle, press the button and watch the ball "perform" the puzzle as it did when you completed the solution.
Yellow Button: Balance puzzle
Blue Button: Tracks-and-huts puzzle
Green Button: Tracks-and-wheels puzzle
Red Button: Mysterious structure (shown after you solved each puzzle)
Walk toward the console in front of you and examine it. You'll spot what appears to be a series of tracks. Along the side of the tracks are four colored icons and lines; these colored icons and lines represent the four puzzles in Amateria (including the fourth mysterious structure you have yet to visit).
To solve the puzzle, you must complete a continuous track that leads into the red icon and line--the mysterious structure you have yet to visit. You must send a ball through all of Amateria's puzzles then complete the trek at the mysterious structure (remember those track segments rising and lowering when you solved each puzzle) to complete the age and receive the symbol.
 Here's the completed Amateria tracks puzzle. |
You must connect the tracks from blue to yellow to green then finally to red to complete the puzzle. The easiest way to connect the tracks is to start at the red icon and work backward.
Number the nine segments from left to right and top to bottom 1 through 9. In its initial state, activate the following track pieces to complete the puzzle: track 2, track 3, track 5, track 5, track 7, track 8, track 9. The other tracks can remain in their starting position.
Press the blue button (to start the ball at the tracks-and-huts puzzle) to begin the age's final, amazing cutscene! After your ride, you'll end up inside the mysterious structure. You'll automatically copy down the age's symbol. After receiving the symbol, use the nearby J'nanin linking book to return to the lesson age.
You're inside the observatory. Walk to where you activated the message from Atrus and Saavedro. Take the symbol from your inventory and place it on the small table to the left of the hologram button. After placing the symbol, you receive another message from Saavedro. Further, the cage containing his linking book gets closer to your position. Both Saavedro's message and the cage position depend on whether you complete Amateria first, middle, or last.
