Bring Back The Sun: Lava Temple Walkthrough (Roblox)

The Lava Temple is the fifth map in Bring Back The Sun on Roblox, sitting between the Restaurant and the wizard castle finale. It stacks four separate puzzles in one run — a shapes-based keypad, a flame color match, a positional canvas, and a statue rotation — and clearing all of them awards the Burning Heart of the Earth, the fourth and final legendary relic. Expect roughly 45 to 60 minutes on a first attempt.

Quick answer: The Lava Temple shapes lock is 2118111. Enter it as 211 on the first keypad and 8111 on the second.

Before you start: three relics required

Lava Temple is the last relic map, so the finale will only accept you once you already hold the three earlier legendary items. Grab them from Sinister Forest, Ancient Ruins, and the Restaurant before you commit to this stage.

Map	Lock	Relic
Sinister Forest	9898	Tear of the Forest
Ancient Ruins	882	Shard of the Fallen Sun
Restaurant	1573	Gift of the Ancient Grain
Lava Temple	2118111 (shapes)	Burning Heart of the Earth

Note: the earlier four-digit codes do not work here. Entering 882 or 1573 on the Lava Temple keypad will fail, because this map derives its code from symbol math instead of a fixed password.

How to solve the shapes code (2118111)

The code is built in three parts. You collect five shapes from a broken glass panel, pull a lever to reveal number values, then plug those values into short formulas to get each digit.

Pick up the rock lying near the entrance and use it to smash the marked stained-glass panel in the corridor. This exposes a plaque of symbols behind the glass.

Read the nearby book. It says yellow means okay, so follow the yellow line through the symbol chart and ignore the purple line. The yellow route gives three symbols on the top row and two on the bottom, in this order: circle, triangle, rectangle, triangle, cross.

Pull the lever on the wall. It spawns a scroll on a pedestal that assigns the number values you need. Note them down before decoding.

Symbol	Value
Pi (π)	2
Delta (Δ)	9
Zero (0)	1
T6	8

Apply the formulas from the book to your five shapes. Each shape maps to a value or a small sum.

Order	Shape	Formula	Digit(s)
1	Circle	Pi	2
2	Triangle	Pi + Delta (2 + 9)	11
3	Rectangle	T6	8
4	Triangle	Pi + Delta again	11
5	Cross	Zero	1

Run the digits together in order — 2, 11, 8, 11, 1 becomes 2118111. The map uses two keypads, so type 211 on the first and 8111 on the second. A correct entry prints “A correct code has been entered” and the red door opens.

If the lock rejects your input, confirm you traced only the yellow line and pulled the lever before reading the formulas. The math almost never changes between patches, but the lever values are worth re-checking first.

Flame color puzzle: set all four torches

The next room has four torches and stained-glass reference panels on the walls. Each panel shows a color pattern with a missing pane, and you cycle the matching torch flame to whatever color belongs in that blank slot. The door only opens when every torch matches at once.

Torch position	Missing pane	Flame color
Right side, near entry	Below yellow	Orange
Right side, opposite entry	Bottom left	Purple
Left side, opposite entry	Next to yellow	Yellow
Right side, near entry	Top left	Yellow

Read the flames against the glass chart, not against real fire — mixing up yellow and orange is the most common mistake. On mobile, cycle each flame slowly and wait for the confirm click. When all four are correct, the stone teeth blocking the path retract.

Key, pliers, and the lava bridge

A key drops in the same chamber once the torches are solved. Pick it up and use it on the small locker on the wall.

Take the pliers from inside, then cut the rope in the compartment. This lowers a wooden bridge over the lava chasm. Without the pliers, you cannot cross, so backtrack if the bridge stays raised.

Clear the short obby across the floating stone blocks and walk over the lowered bridge. Falling usually resets the platform hops but keeps your inventory.

After landing, press the button on the left wall to open the door ahead. It sits off the bridge, so sweep the left side rather than sprinting straight toward the next room.

Canvas color puzzle: red, blue, green, yellow

The next chamber holds a wall clue with a color sequence and a separate clue showing where each color sits on a grid. A blank six-button canvas nearby is where you enter the answer. Both the order and the positions matter.

Order	Color	Position
1	Red	Top left
2	Blue	Bottom middle
3	Green	Top right
4	Yellow	Bottom right

Press the canvas buttons at those exact positions in that sequence — top-left, bottom-middle, top-right, then bottom-right. Do not tap left to right blindly. A correct entry removes the spider webs covering the statues in the main room. A wrong order leaves the webs in place with no error message, so re-check positions if nothing changes.

Turn every statue to face the center

A poster on the wall reads “all statues must face the center.” Click each statue to rotate it one step until it points inward toward the central plinth, not toward you or the exit. Statues sit on both sides of the courtyard, so work through one side and then the other.

There is no reset button, so check each statue’s facing direction before moving on. When every one points to the middle, the puzzle completes.

Claiming the Burning Heart of the Earth

Once all statues face inward, the Burning Heart of the Earth rises on the central pedestal — in game it appears as a giant tomato — and the dialogue confirms it as the last item the wizard needs. A purple portal opens and the MAP COMPLETED screen shows, with LOBBY and RETRY options plus a note that the next map is coming soon.

If the relic does not spawn, one statue is still facing outward. Sweep both sides of the courtyard again and correct it. With this pickup, you now hold all four legendary relics, which is everything required for the wizard castle boss fight.
