There are a total of 240 challenges laid out by the Riddler for Batman to solve on Arkham Island. This includes finding Riddler trophies, solving riddles, destroying Joker Teeth, finding messages from the Spirit of Arkham, and actually finding Riddler maps.

Intensive Treatment[]

Riddler Trophies:[]

  • Riddler Trophy:
  • Riddler Trophy:
    You'll find it while crawling into the pipeline.

Arkham East[]

Secrets Map:[]

The Riddler's secrets map is in them closest to the Arkham Mansion stairs and statue of Warden Sharp. You can't get in, however, until you've received the security-hacking sequencer.

Riddler Trophies:[]

  • Riddler Trophy:
    This one's sitting out in plain sight, on a little jetty overlooking Gotham harbor. It's near the southern view of the water, though, not the northern... very close to the Arkham Mansion stairs.
  • Riddler Trophy:
    You’ll find this trophy at the very back of the graveyard, near the cliff shore.
  • Riddler Trophy:
    Left of the Arkham Mansion stairs is a locked-off courtyard. Grapple over the wall, run to the back and grapple onto the upper balcony. Behind the column here, facing the view of Gotham City, is a Riddler trophy.
  • Riddler Trophy:
    This one is above the previous trophy, on a flat section of Arkham Mansion's roof. If you look at your map, you can also see that it's the narrowest part of the roof, separating the northern and southern halves of the mansion.
  • Riddler Trophy:
    In the middle of the cemetery is a small wooden shack. The door is open and the trophy is right on the desk.
  • Riddler Trophy:
    Grapple and climb your way to the top of the mansion's tallest tower. On the side with the clock face is the trophy.
  • Riddler Trophy:
    If you're on the tallest mansion tower, and look down towards the circular tower, you should spot a rectangular recess between the slopes of the roof. A trophy is there - just glide down and grab it.
  • Riddler Trophy:
    Located on top of the northwestern guard tower, the one closest to the Arkham North door.
  • Riddler Trophy:
    Left of the Arkham Mansion stairs is a flat courtyard. Smack dab in the center of this courtyard is a destructible piece of flooring. Use your explosive gel and take the trophy underneath.
  • Riddler Trophy:
    This one's in the ground floor guard room closest to the Arkham Mansion stairs and statue of Warden Sharp... the same location as the map. You just need to wait until you have the sequencer to gain access.
  • Riddler Trophy:
    The two guard towers here are linked by catwalks. Where those two walks meet, there's an office. Once you can hack your way inside that office with the sequencer, you'll find both the trophy and an interview tape.

Riddles[]

  • Background Analysis:
    "The legacy of this island has been well and truly buried."

    Head to the cemetery and look for the open, sunken grave. It's well-lit and the headstone is shaped like an "A" for the asylum's founder, Amadeus Arkham. Zoom in and scan the face of the tomb to solve the riddle.
  • Background Analysis:
    "Gotham's greatest family towers over the city."

    This one's easy enough. Just find Wayne Tower on the horizon, zoom in and scan the giant "W".
  • Background Analysis:
    "My challenges appear to those with the correct position in life."

    This is a question mark alignment puzzle. Climb to the very top of Arkham Mansion's tallest tower and face south. The dot is on the floor at your feet, but the top half of the symbol is spread out upon the roofs below. Line them up and scan. (Perspective Riddle)

Chronicles of Arkham[]

  • Chronicle of Arkham #1:
    Left of the Arkham Mansion stairs is a locked-off courtyard. Grapple over the wall, drop down and check the righthand wall - behind the railway - for a tablet.
  • Chronicle of Arkham #2:
    Face the Botanical Garden staircase from the graveyard. You should notice a patch of destructible wall on the side of those stairs. Use your gel or your Ultra Batclaw to get inside and find the tablet.

​Patient Interview Tapes[]

  • Joker's Interview Tape #1:
    The tape is in the southern guard tower. On a desk. Impossible to miss once you're up there.
  • Joker's Interview Tape #2:
    The two guard towers here are linked by catwalks. Where those two walks meet, there's an office. Once you can hack your way inside that office with the sequencer, you'll find both an interview and a trophy.

Joker Teeth[]


  • 1 and 2
    These are halfway up the stairs to Arkham Mansion's main entrance. They don't appear until the story directs you to the mansion, however, and you'll definitely want to get rid of the two snipers on the overhang above first.

    3 and 4
    You'll find these two sets as you're making your way to the Botanical Gardens, looking for Harley's fingerprints. They're at the foot of the long stairs. Watch out for lunging lunatics!

    5 and 6
    These two sets are in the more southern guard tower of Arkham East.

    7 and 8
    These two are on the stairs to the Botanical Gardens. They didn't appear for us until Poison Ivy had turned Arkham's sky red and we were on our way to stop her with the antidote.

    9 and 10
    These two are near the door to Arkham West, close to a ground-level guard room. We didn't spot them until after finishing the game, so can't be sure when they first appear.
