Bring Back the Sun Lava Temple Walkthrough – Math Puzzle

If you’ve made it to the Lava Temple, congratulations—you’ve reached the final map currently available in Bring Back the Sun. And honestly? The game definitely saves its hardest puzzles for last.

Unlike the previous chapters, this map doesn’t just ask you to find keys or solve simple riddles. You’ll be decoding symbols, recognizing color patterns, solving logic puzzles, and paying close attention to clues hidden inside books. It’s one of those maps where a tiny detail can make the difference between solving a puzzle in a minute or being stuck for half an hour.

To save you the frustration, here’s a complete walkthrough covering every puzzle from start to finish.

BRING BACK THE SUN Lava Temple Walkthrough – Puzzle

As soon as the level begins, pick up the Rock nearby.

Use it to smash the glass panel.

Behind the broken glass you’ll discover several strange symbols. At first they don’t seem very useful, but don’t leave just yet—you’ll need some of them for the first code.

Read the Symbol Book

Walk over to the nearby book and read the clue carefully.

One of the pages explains:

Yellow means follow.

Instead of looking at every symbol, only follow the yellow path.

Doing this highlights five important symbols in order:

  1. Circle
  2. Triangle
  3. Rectangle
  4. Triangle
  5. Cross

These are the only symbols you’ll need for the first puzzle.

Activate the Lever

Pull the nearby lever.

This reveals the numerical values assigned to several symbols:

  • π (Pi) = 2
  • Δ (Delta) = 9
  • 0 (Zero) = 1
  • T6 = 8

Now return to the book because it explains how each puzzle symbol relates to these values.

Solve the Symbol Math Puzzle

The book gives each shape a mathematical meaning.

Using the values from the lever:

Circle

Circle = Pi

2

Triangle

Triangle = Pi + Delta

2 + 9 = 11

Since Triangle appears twice, both values are 11.

Rectangle

Rectangle = T6

8

Cross

Cross = Zero

1

Putting everything together gives:

  • Circle = 2
  • Triangle = 11
  • Rectangle = 8
  • Triangle = 11
  • Cross = 1

First Door Code

2118111

Enter the code into the keypad to unlock the next room.

Solve the Missing Flame Colors

The next chamber contains several colored glass patterns and four adjustable flames.

The trick here isn’t guessing colors—it’s identifying which color is missing from each pattern.

After comparing the stained glass designs, set the flames to:

  • First Flame – Orange
  • Second Flame – Purple
  • Third Flame – Yellow
  • Fourth Flame – Yellow

Once every flame matches the missing color in its pattern, the nearby door opens.

Pick Up the Key

After solving the flame puzzle, collect the Key lying inside the newly opened room.

Use it immediately to unlock the next door.

Find the Pliers

Inside you’ll find a pair of Pliers.

These are needed to cut the rope inside the small locker.

Once the rope is cut, a bridge lowers elsewhere in the temple, allowing you to continue.

Without doing this, there’s no way across.

Complete the Parkour Section

Now comes the only real platforming challenge in the map.

Climb through the obstacle course until you reach the top.

Once you’ve made it across:

  • Jump down safely.
  • Cross the lowered bridge.
  • Press the button on the left side.

This unlocks the next puzzle room.

Recreate the Color Pattern

This room introduces another memory puzzle.

Look carefully at the completed color board nearby.

The colors appear in this order:

  1. Red
  2. Blue
  3. Green
  4. Yellow

More importantly, pay attention to where each color is positioned.

Now recreate the exact same positions on the blank board.

If the colors are placed correctly, the spider webs covering the statue disappear.

Turn Every Statue Toward the Center

Once the webs are gone, read the nearby poster.

It says:

All statues must face the center.

Walk around the room clicking each statue until every single one is looking toward the middle.

There are statues on both sides of the room, so don’t forget to rotate them all.

As soon as the final statue faces the center, the puzzle is complete.

Important Items to Collect

As you progress through the Lava Temple, make sure you don’t miss these essential items:

  • Rock
  • Key
  • Pliers

Each one is required to finish the level, so if progress suddenly stops, double-check that you picked them up.

The Lava Temple is easily the most puzzle-heavy map in Bring Back the Sun so far. Instead of relying on one mechanic, it combines math, symbol decoding, color recognition, environmental clues, and a little bit of parkour into one long escape sequence. It can definitely feel overwhelming the first time through, especially if you overlook one of the books, but every puzzle has a logical solution once you know where to look.

If you’ve made it through this temple, you’ve officially completed every currently available map in the game. The only thing left is the upcoming boss fight, so you’re in a great position to jump into the finale as soon as it’s released.
