How to Fix the Elevator in Arknights Endfield Deep Management Post

What to know

• The elevator repair is a logic puzzle, not a combat challenge
• Row and column numbers define exact green tile requirements
• Overlapping shapes is allowed and essential
• Only the final grid state matters, not how many pieces you use

After completing the Deep Management Post Rescue sequence, progression in Arknights: Endfield briefly comes to a halt when the facility’s elevator fails. Instead of a fight or resource check, the game presents a logic puzzle built around grid completion. If you understand the rules, the puzzle is quick. If you don’t, it can feel unintuitive—especially because overlapping pieces is not only permitted but required.

This guide walks you through the elevator puzzle in detail, explains the logic behind it, and shows you how to solve it consistently without guesswork.

Location of Elevator Puzzle in Arknights Endfield

The elevator puzzle becomes available immediately after completing the Deep Management Post Rescue objective. Once the rescue concludes, interacting with the disabled elevator opens the puzzle interface. There are no enemies, timers, or penalties—this is a pure logic checkpoint designed to test pattern recognition rather than combat readiness.

Understanding how the elevator grid works

At first glance, the puzzle looks similar to a block-placement mini-game, but its logic is closer to number-grid puzzles.

The grid

You’re given a rectangular grid made up of empty squares. Your goal is to turn specific squares green by placing predefined shapes.

Row and column numbers

• Numbers at the top of the grid represent how many green tiles must appear in each column
• Numbers on the left represent how many green tiles must appear in each row

These numbers are absolute requirements, not minimums or maximums. A row labeled “5” must end with exactly five green squares.

Puzzle pieces

You’re given several shapes made of connected squares. These can be:

• Rotated freely
• Placed anywhere on the grid
• Overlapped with other shapes

Overlapping does not double-count tiles. A square is either green or not.

The win condition

The puzzle completes automatically once every row and every column matches its required green tile count exactly.

Why overlapping pieces are mandatory

Many players get stuck because they assume overlapping is optional or inefficient. In reality, the puzzle is designed so that at least one overlap is required.

Overlapping allows you to:

• Increase tile density in one row without increasing a column count
• Satisfy high-number rows while respecting low-number columns
• Fine-tune totals when you’re “one tile off”

Think of overlaps as a way to cancel out excess coverage, not waste it.

How to fix the elevator in Deep Management Post

Step 1: Scan the grid before placing anything

Start by reading all row and column numbers. Identify:

• Rows with very low numbers (they restrict placement the most)
• Columns with very high numbers (they need dense coverage)

This mental map helps avoid early mistakes.

Step 2: Anchor the largest shapes first

Large pieces have the fewest valid placements. Try rotating and positioning them so they contribute to:

• High-count rows
• High-count columns

At this stage, ignore overlaps—just focus on broad coverage.

Step 3: Check totals after every placement

After placing a piece, quickly re-count affected rows and columns. If any line already exceeds its number, undo immediately. The puzzle is forgiving, so constant adjustment is expected.

Step 4: Introduce overlaps to correct overflows

When a row needs more tiles but a column is already full (or vice versa), overlapping becomes the solution. Place a shape so that:

• New tiles add coverage where needed
• Overlapping tiles avoid increasing completed lines

This is usually where the puzzle “clicks.”

Step 5: Resolve low-number rows last

Rows or columns with small numbers (like 2 or 3) should be finalized near the end. They act as constraints that confirm whether your overlaps are correct.

Step 6: Final puzzle solution

Before confirming, manually verify:

• Every row matches its number exactly
• Every column matches its number exactly

Once all values align, the elevator powers on automatically.

Common mistakes and how to avoid them

Mistake	Why it causes failure
Avoiding overlap	Some layouts are mathematically impossible without it
Filling rows only	Columns overflow easily
Ignoring low-number rows	They restrict valid placements
Resetting too often	Small adjustments are faster than full resets

Why this puzzle exists in Arknights Endfield

From a design standpoint, the elevator puzzle serves two purposes:

1. It introduces players to overlap-based grid logic, which appears in later facility and systems-related mechanics
2. It breaks up combat pacing after a story-heavy rescue sequence

The game deliberately allows unlimited retries to encourage experimentation rather than punishment.

What happens after fixing the elevator

Once solved:

• The elevator becomes fully operational
• You gain access to deeper facility sections
• No additional enemies or puzzles trigger immediately

This makes the puzzle a clean progression gate rather than a branching challenge.

Tips to solve it faster on repeat playthroughs

The Deep Management Post elevator puzzle looks intimidating at first, but it’s one of the most forgiving logic challenges in Arknights Endfield. Once you understand that overlapping is not a trick but a core mechanic, the solution becomes straightforward. Focus on exact counts, adjust incrementally, and let overlaps do the heavy lifting.

• Start with highest-number rows and columns
• Use overlaps early instead of “fixing later”
• Treat pieces as coverage tools, not fixed solutions
• Remember that visual neatness doesn’t matter—only numbers do
