Digit Delivery Service:
Each complete row can be interpreted as a digit delivery instruction.
The difference between the 1st and the 2nd digit indicates a row.
The difference between the 3rd and the 4th digit indicates a column.
The difference between the 5th and the 6th digit indicates a digit.
Place the digit in the tile with the indicated row and column number.
Example: if a row reads “521634” you have to insert a 1 into r3c5.

Some self-reflection: when you read all the rows backwards, you get another valid set of instructions. Following these instructions would deliver the same digits to the same locations. The grey line is a palindrome line. Digits on this line must read the same from both directions.
