Red brick 01/20: Studs x2 (Studs: 250 000)
Area: Bricksburg
In the area with the fountain, nearby is a crane up a building. Use a character with Flight (Superman, level 14) to fly up there. Alternatively, go to the Police Station, break the rainbow blocks using Kitty, and rebuild it into a catapult to get up there. At the back of the crane is an repair point. Switch to a construction worker and fix to cause the crane to spin and launch a chunk of fountain to the area below. Back down, push the chunk along the push area to the front of the fountain and put it on the green tile.
Once there, the red brick will appear.
Red brick 02/20: Studs x4 (Studs: 500 000)
Area: Old West
In the main area there is a man in front of the bank wanting some help with some bank robbers. Near the building to the left, is a master build spot. Use it to create a staircase up the building. Once up, push the crate to the edge so it falls down. Once broken, rebuild it into a fire panel. Use any explosives character to ignite the panel to set the building on fire. Protect and serve. Once on fire, the bank robber will come out and drop the gold bar. Pick it up and take it back to the safe (in front of the bank).
At the top of the Saloon, use a character with a staff to open the door and find the bank robber. Return the gold bar to the safe.
To the right of the Sheriff Office on the roof is a toilet which can be broken with a grapple point. The bank robber is inside. Return the gold bar.
Once all three gold bars are back, they turn into a red brick in the bank.
Red brick 03/20: Studs x6 (Studs: 1 000 000)

With the area change portal behind you, look out and to the right. From the main area, use a heat ray character and jump over the multiple spinning platforms, or fly to access this area. There are three sets of pictures and buttons here. For each picture with buttons in front of it, there is another complete picture nearby. Each button, when stepped on, will rotate a panel. Match the three panels to the picture nearby. When each panel is complete, it will lock. You will need to get this spot on for it to do so.
Once all three panels in each of the three pictures has locked, the red brick will appear.
Red brick 04/20: Studs x8 (Studs: 2 500 000)

From the portal go straight through the jaw doors and follow the red path to the right, then left, follow round to the left. Then in the next room, turn left off the path. Fly up to the upper area above the tv studio (or use an agility character on the wall to the right and jump across) to a bank of three computers with switches in front of them. One of these computers opens the door to the tv studio. Walk through the entrance to level 12 (don't activate it) to get into the studio. Once inside, spin the wheel in the middle of the room to activate random events. Destroy or collect whatever spawns to allow you to make another spin.
After enough spins, it will land on the red brick symbol and spawn the red brick.
Red brick 05/20: Studs x10 (Studs: 5 000 000) – Don't attempt this until you have completed the game.
Area: Bricksburg
In the lower part of Bricksburg, there is a lady (Mrs Scratchenpost) who wants you to find her cats. To the left of Mrs Scratchenpost is a red bench. Destroy it and rebuild into a grapple point on a balcony. Grapple the balcony down and and cat will follow you back to Mrs Scratchenpost. Alternatively, you can fly up to the balcony to get it to follow you. Cats are good at landing.
Climb the nearby train station and use a hacking character to hack the terminal. The nearby doors will open and the cat will come out and follow you. Take it back to Mrs Scratchenpost. The cat has good speed and will always land on its paws, so feel free to take gravity shortcuts and run back to Mrs Scratchenpost.
In the fountain area, on the top of a nearby building is a crane. To the right of the crane is a port-a-loo with a target on it. Fly up there, or alternately go to the Police Station, break the rainbow blocks using Kitty, and rebuild it into a catapult to get up there. Switch to any projectile character to let the cat out of the box. Again, the cat is resilient to the effects of death, so jump off the building to get back faster. Take it back to Mrs Scratchenpost.
In the fountain area, near the construction site, is a panel that only Lord Business (level 15) can use. Switch to him and use the panel to gain super legs. Head to the other side of the fountain to the tree to the right of the station. Use the high switch to open the station doors. Swap to your other character to enter the station, as this cat will not automatically follow you until you get close to it. Take it back to Mrs Scratchenpost.
From Mrs Scratchenpost, on the other side of the lower area, in a corner is a red building with a fence on top. In the smaller area is the cat, so use a flight character to get the cat and come back down. Take it back to Mrs Scratchenpost.
Once all the cats are back, the red brick will appear.
