The puzzle shows nine 4×4 grids, each with a hexadecimal label. Following the rules of the Art Pricing module (hinted by “art” in the flavor text and “Price” in the title), we should XOR each grid with the hex code in its label (where each hex digit represents a row of pixels).
The resulting new 4×4 grids can each be found as sub-grids in the Grid Matching manual (hinted by “grids” in the flavor text and “Matching” in the title). Each 6×6 grid in that manual is associated with a letter from A to P.
| Given grid | Hex label | Grid after XOR | Grid Matching grid and letter | |
|---|---|---|---|---|
| 8D12 | D | |||
| 7777 | E | |||
| F630 | M | |||
| AB03 | A | |||
| 1248 | N | |||
| 58CE | D | |||
| EEFB | I | |||
| BD29 | N | |||
| B701 | G | |||
Concatenating the letters gives the answer.
