The Riddler is a supporting character in the 2009 video game, Batman: Arkham Asylum. The Riddler contacts Batman via radio and gives him the task of completing 240 "Riddler Challenges" spread across Arkham Island.


With an obsessive need for attention, Edward Nigma is determined to be the most outlandish of Gotham City's criminals, concocting elaborate series of clues and riddles around his crimes. Batman has proven a worthy opponent, capable of deducing the Riddler's plans, but Nigma is dedicated to creating a mystery the Dark Knight will not be able to solve in time.


  • Genius intellect
  • Driven by a need to test his wits against law enforcement by leaving clues to his planned crimes
  • Compulsive need for attention

Batman: Arkham AsylumEdit

The Riddler was one of the many inmates who escaped Arkham Asylum after the Joker took control of the island. The Riddler made his way to a hidden location in Gotham City and contacted Batman by hacking into the communication signal the Dark Knight used to contact Oracle. In order to boast his superior intellect, the Riddler had organized a series of riddles around the island, ranging from a number of small trophies hidden in out-of-the-way spots to elaborate perspective puzzles. After escaping, he challenged Batman to find these, along with the additional challenge of solving riddles that described specific objects in various rooms.

Batman steadily solved every riddle, with the Riddler boasting his superiority to begin with but slowly becoming more enraged with Batman. Before solving the last few riddles, Batman located the Riddler's signal and notified the police of his whereabouts. After solving his final riddle, the Riddler began to implement Gotham's "greatest riddle." But before he could do so, the GCPD broke into his hideout on 229 O'Neil Avenue in Old Gotham. The police arrive there and arrest Riddler as he quotes to Batman that he cheated on his riddles.


Each unique set of locations in the game (e.g. one building or one of the island sections) has a number of associated Riddler Challenges, which can be solved to earn XP and unlock bonuses, such as character profiles, character trophies, and challenge mini-games. There are several distinct types of challenges:

File:Ark mansintensive-teeth-4--article image.jpg
  • Riddler trophies: These green question-mark statues are scattered all over, sometimes out in the open, sometimes hidden in difficult-to-access areas.
  • Riddles: More or less cryptic clues describing specific locations or objects. To solve the riddle, the described object or scene must be visible on-screen and must be "scanned". These range from obvious (One riddle simply name-drops Prometheus and requires Batman to scan a wanted poster for the villain) to the cryptic (one riddle mentions the "end of days" for a murderer, referring to the cell where the Calender Man sleeps).
  • Joker Teeth: The Joker has scattered a lot of "chattering teeth" gag toys, often in groups of two or three. To fulfil the challenge, a certain number of teeth (5, 10, 20) must be destroyed.
  • Perspective riddles Two halves of a question mark have been painted on the scenery (only visible in Detective Mode). When viewed from the right perspective, they line up to form a whole question mark, which can be scanned to solve the riddle.
  • Interview tapes: Audio tape reels containing patient interviews and doctor's notes can be found in many locations, giving insight into some of the major characters in the game.
  • Chronicles of Arkham: All over the Island there are scribbled messages on decorative stones, in the same spiralling style that Amadeus Arkham once used. Batman must scan these messages to decode them.
  • Riddler maps: Each location set contains one map which reveals the approximate placement of all the other challenge items, by placing floating question marks on the in-game map.

Some of the items are initially inaccessible and can only be accessed after Batman has collected a specific gadget. Since this requires revisiting locations when the actual plot of the game does not require it, the game allows the player to continue exploring the island, even after the reaching the end, in order to achieve 100% completion.


The many riddles and puzzles the Riddler has scattered through Arkham include cryptic clues describing specific locations or objects. To solve the riddle, the described object must be visible on-screen and must be "scanned". The Riddler will pose actual riddles for Batman to solve in specific areas throughout Arkham, who will be notified as soon as he enters a room. These riddles are generally solved by one of two ways but the means in which you solve them remains the same. Batman will either need to find a specific object the Riddler is talking about or find a disjointed question mark symbol and line it up from a certain perspective.

  • Riddle 1: "Don't cut yourself on this sharply observed portrait."

After receiving the first message from the Riddler in the Intensive Treatment Lobby, Batman must turn around and look to the left of the ladder for a portrait of Warden Sharp, scanning it to solve the riddle.

Before leaving the Intensive Treatment Lobby, Batman must look around the windows of the offices in the middle of the room to solve this puzzle. He's looking to put together a hidden question mark. It's body will be separated from the period. Batman must use Detective Mode to find the body of the question mark on a window of the office, then turn around until he has lined up the dot on the wall just underneath the body. When it looks like a "?", Batman must scan it to complete this riddle.

  • Riddle 3: "You don't know Jack about Gotham. Tune in to find out."

To solve this riddle, Batman must enter the Utility Corridor of the Intensive Treatment Center. When he enters the guards' locker room, Batman must listen for the sound of a radio and find it.

In the security guards' control office, on the upper level of the Main Cell Block, is The Ventriloquist's tommy gun mounted on the wall. Batman must scan the machine gun to solve this riddle.

As Batman continues to solve all 50 riddles and collect the items, Riddler initially taunts him with the "slowness" of his progress, but becomes increasingly agitated, as the amount of solved riddles rises. He accuses Batman of cheating, possibly by looking up the riddles on the internet. Once enough riddles have been solved, Batman manages to deduce Riddler's current location and transmits it to the Gotham Police.

Final Audio RecordingEdit

After Batman has solved the final riddle, the Riddler will panic. The following recording is released as the Riddler is thwarted.

The Riddler: "What?"

(The Riddler realizes that Batman has just solved his final riddle.)

The Riddler: "You did it?? You must have cheated. There is no way you could have beaten me."

The Riddler: "Well, you asked for it, Batman. My final challenge for the whole of Gotham is just seconds away....Wha?"

(Sirens begin to sound in the distance.)

The Riddler: "Sirens! The police! You cheated, Batman. You couldn't have outsmarted me!"

(Several policemen pound on the door)

Police Officer: "Police! open up."

The Riddler: "No!"

Police Officer: "I said open the door, now!"

Police Officer: "Now!!"

(There is a splintering of bolts as the police knock down the door.)

Police Officer: "Down on the ground! Down on the ground!"

(Several more policemen burst into the Riddler's hideout.)

The Riddler: "No!!"

The Riddler: "Tell me! how did you work out where I was?? Do you hear me? I, Edward Nigma, will....argghhh."

(The Riddler struggles against the police officers and one strikes him with a nightstick.)

Patient InterviewsEdit

File:Batman: Arkham Asylum - Patient Interview Tapes - The Riddler

Patient Interview #21, May 27th
In the first patient interview, Dr. Penelope Young confronts the Riddler on the matter of writing threatening riddles on his cell walls. The Riddler, on the other hand, states that one should have to be severely paranoid to derive threats from harmless riddles. He asks Dr. Young if he can test one on her, to which she agrees. The Riddler asks the well known riddle: What walks on four legs, then two legs and finally three? Dr. Young answers with the correct answer of a human being: crawling on all fours as a baby, walking on two as an adult and finally uses a cane in old age. The Riddler commends her on her answer yet states that correct one is a baby for all three. He claims that it's true a baby crawls on all fours but if you cut off its legs it can only move with two, give it a crutch and it can hobble along on three. Dr. Young, obviously disturbed, asks how the Riddler can joke about such things, to which the Riddler replies "Easily doctor. It's not my baby..."

Patient Interview #39, July 29th
The second interview begins with Dr. Young still undecided of whether to use the Riddler for the Titan process. Dr. Young begins by wanting to ask about the Riddler's childhood which she believes his fascination of riddles began and would also explain his compulsive behavior. Reluctantly, the Riddler agrees, stating the his father hated him and always called him a moron, causing the Riddler to try and prove him wrong. As a result he entered a contest at school, a $20 prize for the child who solved an almost impossible logic problem. The Riddler claimed that "I won of course" yet his father kept yelling "You must have cheated! Admit it you moron, you cheated!". He swore he didn't and his father beat him for lying. Dr. Young, feeling pity for the Riddler, is sorry to hear about the incident to which the Riddler replies "Don't be. He was right"

Patient Interview #44, August 21st
In the third interview, Dr. Young attempts to discuss the Riddler's large variety of riddle-based schemes in his career which resulted in numerous deaths. The Riddler claims that society should be thanking him, for ridding the city of the stupid and the ignorant. He goes on to claim that if the citizens of Gotham was smarter, his riddles would be mere distractions for amusement, to which he tells Dr. Young that he'd be sure she would be able to solve them. He then turns his attention to a family photo on Dr. Young's desk causing Young to panic and call for security.

Patient Interview #55, October 4th
The fourth interview has Dr. Young trying to delve into the Riddler's obsession with Batman. The Riddler on the other hand claims they're merely observations. Observations that Batman is himself a criminal and no different from criminals such as Two-Face, the Joker or even himself. He states that Batman must be stealing from the criminals he defeats in order to pay for his high-tech equipment and vehicles and that he must also be bribing Commissioner Gordon so as to keep the GCPD off his back. When Dr. Young states that most see him as a hero, the Riddler becomes enraged with her, causing Dr. Young to call in the guards.

Patient Interview #76, January 16th
The final interview with the Riddler has Dr. Young state that she can no longer put up with his mood swings and will be transferring him to Dr. Gretchen Westler. The Riddler appears incredibly cheerful, much to Dr. Young's surprise. After asking why he feels this way, the Riddler states that he's "always in high spirits when he's about to be released". Young becomes confused as the Riddler can't go for parole for another three years. The Riddler seems to ignore this statement, going on that the first thing he'll do is go to a particular Italian restaurant, hoping that the Joker hasn't destroyed Gotham by then. Dr. Young becomes particularly worried that the Riddler may have had contact with the Joker, who had escaped a few weeks earlier. The Riddler states that he heard something about Joker's future plans for a "surprise party" involving Batman, saying "you know Joker, yak yak yak". Dr. Young demands that the Riddler tell her what he heard, as lives are stake. The Riddler finally replies, "You forget doctor, I'm the one that asks the riddles..."
