The reactor puzzle in DERELIKT can be a little confusing when you first encounter it. The objective is to manipulate the hexagonal grid and generate enough heat to trigger a reactor meltdown.
The terminal in the room explains the basic mechanic, but figuring out the correct order of selections can take some trial and error. If you’re stuck, this guide covers the rules and a working sequence you can follow.
Before starting, make sure you reset the grid. The solution below assumes you’re working with the puzzle in its original starting state.

The puzzle uses three heat states represented by different hexagon colors:
- Cold (Off): The hexagon is inactive.
- Warm (Red): The hexagon has gained heat.
- Hot (Yellow): The hexagon has reached its highest heat state.
You can select Cold and Warm hexagons, but you cannot directly select Hot ones.
Selecting a hexagon changes the heat propagation of the surrounding hexagons. Their states cycle through the following order:
Cold → Warm → Hot → Cold
Your goal is to select the hexagons in the correct order to generate as much heat as possible and trigger the reactor meltdown.

Reset the puzzle before following these steps. The sequence below uses the field names from the solution, along with their positions, to help you identify the correct hexagons.
Some fields share the same name, so pay attention to the position descriptions rather than relying on the names alone.
| Step | Field | Position |
|---|---|---|
| 1 | 10B1 | Upper left, inside |
| 2 | 10B3 | Lower left, inside |
| 3 | 10B2 | Middle left, inside |
| 4 | 10B4 | Bottom left, outwards |
| 5 | 10C1 | Topmost |
| 6 | 10C2 | Middle top |
| 7 | 10C1 | Topmost |
| 8 | 10C2 | Middle top |
| 9 | 10B4 | Top right, inside |
| 10 | 10B3 | Top right, inside |
| 11 | 10B1 | Lower right, inside |
| 12 | 10C1 | Topmost |
| 13 | 10C1 | Topmost |
| 14 | 10A1 | Lower right |
| 15 | 10C3 | Middle |
| 16 | 10C2 | Middle top |
| 17 | 10C1 | Middle top |
Follow the sequence from Step 1 through Step 17 without changing the order.
Final Tips
- Reset the grid before attempting the sequence.
- Follow the field positions carefully because several hexagons share the same names.
- Do not select yellow (Hot) hexagons.
- If your grid does not match the expected result, reset it and start again.
Once you complete the correct sequence, you should be able to trigger the reactor meltdown and finish the puzzle.
