#Puzzle 1

This room opens after you finish all the Tricorner Riddler Puzzles. Walk inside the room to find a mirror puzzle. Use your Pulse Scan to see what you need. Put the Candle in the center of the table. You get this from the room on the left after you press the Red Button. Put the Boombox on the left Plinth.

Take the Handle from the main room to the broken Crank in the left room. Use it to pull the box down, then break the lock with a Batarang. Move the Lamp from the table to the spot near the door. Last, move the Teddy from the bookshelf on the right to the Piano Chair.

#Puzzle 2

Go to the front of Ace Chemicals at ground level to find this challenge. You will see a small crane. Go into the shed across from it and push the Crate as far as it goes.

Use Nightwing to link the Crate to the Crane. Go above the Crane to charge it so it hits the wall. Finish this by using Batman’s Explosive Spray in LEGO Batman: Legacy of the Dark Knight.

#Puzzle 3

Head to the south part of the area to find this setup. Turn the Lever to move the electricity to the middle row by the Trophy. Quickly switch to your other character and jump to the safe floor next to the Trophy. Switch back to the character at the Lever and pull it again.

Switch back to your other character fast. Move to the middle to stay safe from the power. Now, grab the Trophy.

#Puzzle 4

Use Catwoman for this puzzle found inside the Ace Chemicals gate. You need to find three Keys to open the lock. First, face the water and use Catwoman’s Whip on the screw of the crate on your left to drop it.

Second, stand on the button on the right Shipping Crate with Batman and the one on the left Shipping Crate with Catwoman. Call Kitty, have her stand on the button in front of the Riddler Crate, and grab the Key.

Third, face the water, go down the stairs, and pull the Lever to move the pipe. Use Catwoman’s Whip to spray water and put out the fire. Send Kitty through the small door to get the Key in LEGO Batman: Legacy of the Dark Knight.

#Puzzle 5

Use Jim Gordon to solve this on the mid-west side. Hit the rattling Wheel left of the Trophy with a Batarang. Use Jim Gordon’s Foam Gun to block the water. Follow the big blue pipe to the roof. Break the Crate, drop down, build the pipe section, and pull the Lever.

Go right of the Trophy, find the blue pipe, and use a Batarang to pull it into place. Go left and use the Foam Gun to clog the gears when the blue pipe is at its lowest point. Finally, move left and push the pipe on the trolley into its spot to get the Trophy.

#Puzzle 6

Use Robin or Nightwing at the water on the north edge. Put your back to the Trophy Cage and look left. Use the Batclaw on the panel and hit the Target with a Batarang. Put your back to the Trophy Cage again and look right.

Use your Cable Tether to bridge the gap at the water. Jump on the line, look down, and hit the Target. Face the Trophy Cage and follow the top wire to the roof. Pry the box open with Robin or Nightwing and hit the last Target.

#Puzzle 7

Use Nightwing for this one located to the north. Move the Battery Box under the Trophy Cage as far forward as you can. Put the Battery from the ledge into it in LEGO Batman: Legacy of the Dark Knight.

Go to the area across from the cage. Have Batman stand on the Red Button to raise the middle Target. As Nightwing, shoot all three targets in a row. Start with the green one connected to the Battery Box and move to the left.
