Lego Batman Legacy of the Dark Knight: Gloomy Tunes Riddler Puzzle – Location, Puzzle Solution, and Rewards Guide

Gloomy Tunes in LEGO Batman: Legacy of the Dark Knight is the Old Gotham South Riddler radio puzzle where you must manipulate nearby devices until the wall radio pointer lands on the Riddler symbol. The puzzle sits west of Old Gotham South near the Action News building at map coordinates 285, 338, and completing it rewards 1 Riddler Puzzle Box and 500 Silver Studs.

Step 1: Find the puzzle

Travel to Old Gotham South and head to the open overlook above the train path near the Action News building. The puzzle marker is positioned on the west side of the district at 285, 338, so use the map to line up the correct rooftop area first.

Step 2: Read the gauge

Walk up to the wall radio and study how the pointer reacts when each nearby device is moved. The goal is not to force the pointer straight to the symbol in one move, but to balance the motion so the indicator settles on the Riddler mark.

Step 3: Test one device at a time

Interact with a single device and watch the pointer move before touching anything else.

One device pushes the pointer upward, while another can send it too far or even reverse progress, so make small changes and observe the result.

Step 4: Set the middle device position

Use the second device to raise the pointer partway, then leave it in a stable position instead of overcorrecting. 

Step 5: Cancel the bad move

If the pointer drops too low or overshoots, pull the earlier device back to undo the mistake. 

Step 6: Lock the final alignment

Finish by placing the remaining device in the same stable position as the other adjusted piece so the pointer lands on the Riddler symbol.

Once the gauge opens, the puzzle is complete and the reward chest or box becomes available.

What the puzzle is doing

Gloomy Tunes is a simple mechanical balancing puzzle disguised as a radio tune challenge. Instead of solving a hidden code, you are controlling pointer movement with environmental devices until the radio gauge matches the Riddler emblem. The key idea is that one move can push the pointer too high, so the safe play is to find the middle state and only then make the final alignment.

Rewards and value

The direct completion reward is 1 Riddler Puzzle Box and 500 Silver Studs.

The bigger value is progression, since this puzzle contributes to your broader Riddler puzzle collection and 100% completion tracking in the game. If you are chasing every puzzle in Gotham, this one is a quick win once you understand the pointer behavior.

Common mistakes

• Moving every device at once, which makes the pointer hard to read and wastes time.
• Overcorrecting after the pointer moves up, then losing the stable position you already had.
• Looking for a hidden code when the puzzle is actually a movement-and-balance solution.
• Missing the location tag and searching the wrong Old Gotham district, especially if you are not already in Old Gotham South.

This is a short, low-friction puzzle that pays out fast, so the real value is efficient progress toward full Riddler completion rather than a rare reward. If you are cleaning up collectibles, Gloomy Tunes is worth grabbing immediately because it costs little time once you know the pointer-balancing trick.
