Lego Batman Legacy of the Dark Knight: Riddler Puzzle Locations & Interactive Tracking Guide
Matching wits with Gotham’s criminal mastermind and bypassing his complex green-glowing traps is a requirement for matching the analytical mind of the world's greatest detective.
Finding and solving all Riddler Puzzle locations is the best way to access closed-off regions, uncover highly guarded secrets, and complete advanced open-world challenges in Lego Batman: Legacy of the Dark Knight.
These environmental brain-teasers are scattered throughout high-altitude rooftops, abandoned subway tunnels, and city landmarks.
Solving them grants access to the rarest collectibles hidden behind question-mark barriers.
All Riddler Puzzles in Lego Batman: Legacy of the Dark Knight
Unlike basic switch puzzles, these specific locations are color-coded in vibrant green neon and require specialized mental or visual skills to properly deactivate.
To crack these locations efficiently, you must build a team that can manipulate objects from a distance.
Furthermore, many of these challenges incorporate timed sequence blocks that require rapid reflexes.
Spotting a series of glowing question-mark buttons high on a wall means utilizing Batman’s Batarang to target and strike every icon in rapid succession.
Always scan the immediate perimeter for hidden green wiring trails along the floors and walls, as following these lines will lead you directly to the hidden power sources needed to shut down the trap permanently.
