How to complete the Lightning Round Riddler puzzle
This challenge is primarily about speed and target order. After activating the mechanism, you must quickly hit all three targets before the timer expires.
Activating the puzzle
Pull the lever beside the puzzle core to begin the challenge. This activates the timed sequence and reveals the targets.

Target 1
Hit the first target directly in front of the puzzle mechanism. The first target is positioned ahead of the starting point and is usually the easiest to spot immediately after activation.

Target 2
Turn around and strike the second target opposite the first one. You need to move quickly because the timer continues running during the transition between targets.

Target 3
Hit the final target located beside the satellite dish structure. The last target is positioned slightly to the side near the large satellite dish area.

Collecting the Riddler’s puzzle piece
Return to the main puzzle core and collect the Riddler puzzle piece.
After all three targets are successfully activated, the collectible reward becomes available.
