Batman: Arkham Knight Riddler guide - how to solve every Riddler challenge

Batman: Arkham Knight Riddler guide

Having a Batman: Arkham Knight Riddler guide to hand is essential if you want to 100% complete the game, because there's a whopping 243 Riddler puzzles to solve and that's a massive challenge to take on solo. While being part of the PS Plus Collection games means that PS5 owners can easily check out the finale to Rocksteady's Arkham trilogy, there will players on all formats who still have these puzzles outstanding as the Riddler challenges really are tough!

Edward Nigma has been busy once again setting up puzzles all over the city, and if you're a completionist then you'll naturally want to complete them all, so we're here to help you out with a complete Batman: Arkham Knight Riddler guide. Remember that some trophies will be unavailable until later in the story, and many of them will require Batman's more advanced gadgets to retrieve, so it's recommended that you complete a decent amount of the story before you start chasing them down in earnest. We start with Bleake Island below, before moving on to the other areas around Gotham.

Bleake Island Riddles

"Joining your mission can come with a cost, this empty reminder shows just what she lost."

Head to the Clock Tower and activate Barbara's computer. Look for a console along the wall and use the Remote Hacking Device on it to reveal her Batgirl suit. Scan this to solve the riddle.

"A souvenir from a previous life, why hold with a hand when a hook will suffice?"

Solved within the GCPD Lockup. Scan the Arkham mug at the main desk by Cash.

"Bones stripped bare beneath a warning light, pay heed, seafarers and feel his bite."

To solve this, you'll have to head to the lone tower east of Ace Chemical. Look inside and scan the abandoned cage.

"An open house for bed and dinner, is this sanctuary run by saint or sinner?"

In the northernmost corner of the island, check the storefronts until you find The Deacon's Mission. Scan the sign to solve.

"Always looking for names to besmirch, where does this newsman conduct his research?"

Another one inside the GCPD Lockup. Jack Ryder sits in the Interview Room; scan him to solve this.

"Overgrown, abandoned, the inmates set free, madness could never be held in me."

To solve this, you'll need to scan Arkham Asylum, but finding it is tricky. Head to the western edge of the Falcone Shipping Antenna and zoom in while looking across the water to spot it.

"Hope shines brightly in a city this dark, find the source of that signal and you'll soon hit your mark."

Go to the roof of the GCPD Lockup, then find the corner tower with the Bat-Signal spotlight on it and scan to solve.

"A bat uses these to see at night, the doc's didn't work and his cure caused a fright."

Solved in Dr. Langstrom's lab. Once you start the Man-Bat mission, you'll be sent here. Scan the drawing on his whiteboard.

"I bet you weren't invited to this lavish do, I wonder how many went dress up as you?"

This is found inside the Clock Tower. Bust through the east-facing windows and head to the top floor. Check by the elevator shaft for this masquerade ball advertisement and scan it.

"She stands at our center that we may not weaken, a symbol of hope, a towering beacon."

This is an easy one. Glide to the tiny island in the center of the three main ones. Scan the large statue to solve.

Bleake Island Trophies

GCPD Lockup

Check by the main desk in the Evidence Room to find this inside a case.

Urbarail bridge near GCPD Lockup

Northeast of the GCPD Lockup, find this bridge with a video advertising board on it, then grapple up to the bridge platform and look in the nearby control room to find this.

Under Urbarail bridge near GCPD Lockup

Just under the very same control room is a Riddler puzzle. Hit the Riddler switch with your Batarang to step inside, then use the Batmobile's remote function and winch to move the walls out of your way.

Kord Industries

This is found in the central part of the Kord Industries plaza. Look up to find a destructible wall, and blast it away with the Batmobile's cannon. Use the Batclaw to grab the trophy hanging on the other side.

Kord Industries

On the eastern tower of the Kord plaza is another trophy, but you'll have to travel to Miagani Island to free it from its cage. Drive to the bridge on the southern end to find a panel you can charge up with the Batmobile's winch. This will start a timer on the trophy's cage. Floor it back to Bleake Island, then launch yourself and grapple up to the trophy before time expires.

Panessa Studios

Get on to the roof of Panessa Studios proper, then either drop through the broken skylights or head down the stairs from the helipad to enter an interior corridor, before crouching through the open vent to enter a backstage area where this trophy waits.

Panessa Studios

Check near the northwestern wall of the main building to find a large pressure pad. Drive the Batmobile onto this to activate some Riddler switches on the wall nearby. Shoot each one as it appears to open the lock in the center, then grab the trophy using your Batclaw.

Panessa Studios

This is smack dab in the middle of the parking lot, atop a tower lined with Riddler switches. To get at them, you'll need to latch onto the tower base with the Batmobile's winch and rotate the glass until the windows give you access. Hit all three switches to lower the tower and free the trophy.

Panessa Studios

Follow the path to the studio rooftop - the same one you used when you first got the Batmobile's winch. Once up here, activate the Forensic Scanner near the green panel. This will make Riddler symbols appear on the ground. Follow them as they appear to be led through a sewer to the canal at Dixon Dock West. Look up to spot another panel under an overpass. Blast this open and use the Batclaw to fetch the trophy inside.

Panessa Studios

Check the studio rooftop for a Riddler bot standing near two switches. Use the Voice Synthesizer to order him onto one switch, then step on the other to free the trophy up for the Batclaw.

Panessa Studios

Check the back wall of the northernmost building on the lot to find a weak spot. Blow through it then grapple into the alcove to find this.

Panessa Studios

Check the roof of the same building for another weak spot. You'll have to navigate the Batmobile up here to blow up this one, though: use the same course as when you first receive the winch during the story.

Panessa Studios

Now check the rooftop nearest Merchant Bridge. There's a spot to jack in the Batmobile's winch and charge up via the engine. Do this to create a new waypoint a good distance away. A timer starts, so gun it to this new location in Chinatown and quickly grapple to the marked rooftop to grab the trophy before it gets locked away again.

Panessa Studios

Check by the ledge at the northern end of the lighthouse hill to find this in a little shed.

Panessa Studios

Just south of the lighthouse is one of Riddler's puzzles. This one is a bit tricky. First, use the Batmobile winch to pull out a concrete slat. Hop out, apply some Explosive Gel, hop back in, and return the slat to its original position. Detonate the gel to destroy a pump inside, clearing out the harmful steam at the end of tunnel. Now pull the slat back out of the way, and do a running slide through the small opening, past the shut-off valves, and into the container. The trophy is all yours!

Panessa Studios

Just south of the previous trophy is another puzzle, down in a ditch. This one works a bit like pinball. Use the winch to pull back and release the block to launch the trophy ball. A few launches will get it into the prize slot, where you can pick it up.

Merchant Bridge

There's a small building below Merchant Bridge. Drop down to find a trophy by a beach chair on the roof.

Falcone Shipping Antenna

Check the southern edge of the facility to find another puzzle. Use the Batmobile winch to pull the train forward, taking it off a grate. Head back there and slip into the grate to find a trophy underneath.

Warehouse near Mercy Bridge

Check just on the east side of the Bleake Island side to find a Riddler puzzle inside a warehouse. This is one is kinda tough. First use the Batmobile winch to pull down the wall of questions marks. Next, you need to shoot each one as it passes under the rings along the wall. It may take a few tries - make sure you hit the center mark last - but doing so will net you another trophy.

Near Ace Chemical Bridge

There's a weak wall just a bit higher up from the warehouse you just entered. Bust through with the Batmobile's cannon to find this on the other side.

Near Ace Chemical Bridge

There's a Riddler puzzle just east of the Chinatown side of the bridge. Grapple up there to find a Riddler bot, a cage, and an electrified floor. Use the Voice Synthesizer to command the bot across the floor, bringing the trophy to you.

Ace Chemical Bridge

If you actually head out on the broken bridge, you can find a small structure underneath towards the end. Grapple to the ledge down here to find another trophy.

Ace Chemical Tower

There's a lone tower east of Ace Chemicals. Grapple to the top ledge to find this.

Chinatown Hotel

In the northernmost corner of the island is a rundown hotel. Head around back to find a wood panel you can bust through. Do so, then grapple up to the hole to find a trophy inside.

Dixon Dock West

There's a warehouse across from the docks proper. Drive through the splintered door with the Batmobile, then grapple up to the catwalks to grab this.

Dixon Dock West

On the northern end of the dockyard is a suspended shipping container. Grapple up there, then drop into the open end to find a trophy inside.

Clock Tower

Across the street from the Clock Tower is a Riddler puzzle. First, use the Batmobile's winch to pull the wheel inside the cage forward. Next, shoot an electrical charge into the generator on top to power the other cogs, temporarily opening the door. Quickly grab the trophy from inside.

Clock Tower

Grapple up the balcony above the Riddler puzzle. Head inside the abandoned building to find another trophy.

Clock Tower

The building north of the Clock Tower has another Riddler puzzle for you. You can't collect the trophy yourself thanks to the electrified floor, so use the Voice Synthesizer to send the Riddler bot inside. Have him dismantle the first sentry gun, then use the Remote Hacking Device to temporarily disable the other. Command the bot to grab the trophy and bring it you. Score!

Coast Guard Station

The station is directly south from the Clock Tower. Check underneath the boardwalk to find a trophy, and use your Batclaw to fetch it.

Earl Cooper Auto Repair

This auto shop is across the street from the Bank of Gotham in Chinatown. Use the Batmobile's Forensics scanner on the green symbol to make Riddler marks appear on the ground. Follow these - you'll have to double back and get onto the bridge - to find a spot you can blast open with the car's cannon. Grapple up to get the trophy inside.

Earl Cooper Auto Repair

There's a storage unit atop the shop. Use your Batarang on the switch to raise the containers inside, then head over the pressure pad. Step on it and use the Batclaw to yank the trophy your way, causing a bunch of Riddler bots to appear. Save yourself the fight: use the Remote Controlled Batarang to hit the other switch on the containers and drop them on the minions.

Near Ace Chemical Bridge

On the Chinatown side of the bridge is a green handle in a column. Use the Batmobile's winch to pull the trophy out from inside the building.

Near Ace Chemical Bridge

On the opposite side of the Chinatown bridge end is a large warehouse; you can get inside via the waterfront. There's a trophy inside.

Rooftop near Osamu Tower

Osamu Tower stands in the heart of Chinatown, and this rooftop to the southeast is home to three Riddler bots. For each one you defeat, a light next to the locked trophy will glow. You can hit the switch to revive the three downed bots. Defeat each one three times to unlock the trophy.

Bleake Island Riddler Victims

Chinatown

Head northeast from Perdition Bridge into Chinatown, and grapple to the next overpass directly after the "Welcome to Chinatown" sign. Step on the switch here to activate a Riddler video. When it's over, use the Remote Batarang to scan the rioters and find the bomb victim. Throw another Batarang through the nearby electrical field to charge up, then nail him to deactivate the bomb.

Chinatown

This one is at the northeast edge of Chinatown, near the hotel. Step on the switch, use your Batarang to find the victim, and use another Batarang to pass through the current near the hotel sign to take him out.

Clock Tower

The last victim is found just east of the Clock Tower, and the Riddler switch is on a rooftop overlooking the parade float nearby. Use the Remote Batarang to find the victim, then guide a second one through the electricity on the Urbarail track above and knock him out.

Bleake Island Militia Shields

GCPD Lockup

Attached to the building, facing the highway to the east.

Kord Industries

Found in the center of The Cauldron, hanging on the southernmost wall of the building.

McKie's Gems

In Central Bleake Island, look up a wall in an alleyway by McKie's Gems store.

Dixon Dock West

Found in the dry canal next to the dock.

Dixon Dock West

A little further north along the same wall, over the water.

Clock Tower

Just east of the Clock Tower, look high on a tower across the road from the hotel.

Clock Tower/Chinatown

Head north from the Clock Tower to find this just on the Chinatown border, high up on a building.

In the north end of the parking lot. Look up at the overpass to spot it.

Panessa Studios

Found on a scaffolding on the road to Merchant Bridge.

Panessa Studios

Also near Merchant Bridge. Check the eastern side by the lighthouse.
