Riddler Challenges are, as their name implies, a series of riddles, puzzles, and hidden extortion data, trophies, interview tapes, and destructible items that are placed throughout the four main games of the Arkham Series by staple villain, Edward Nigma, aka the Riddler. Below is breakdown of each challenge, respective of each of the four games, and the solution that is necessary to complete it.

Gotham Pioneers Bridge:
Arkham Asylum Challenges
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 mansguardtowerArkhamInterviews 01.jpg The Riddler challenges Batman to find these audio reels scattered throughout Arkham Asylum in doctors' offices, guard towers, and sometimes strewn around across the floor and in the unlikeliest of places. These tapes may require some serious searching to locate, but provide interesting psychological depth on Arkham Asylum's most infamous inmates. This reel (above) is on a wooden desk in the nest of the Arkham East guard tower.*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 Calendar Man sleeps).
- Joker Teeth: The Joker has scattered a lot of "chattering teeth" gag toys, often in groups of two or three. To fulfill 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 spiraling 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.

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. Its 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.
