The Resident Evil 4 remake features several intricate environmental brainteasers that challenge players as they progress through major story chapters. Among the most notable challenges in the castle section is the lithographic stone puzzle located inside the Bindery. Mastering this puzzle requires collecting scattered stone plates and placing them in their proper slots based on specific visual criteria.

Finding the Required Lithographic Stones

Before you can begin placing pieces into the wall slot, you must gather all four lithographic stones scattered throughout the Bindery room. Lithographic Stone A is already placed inside the door frame, serving as your initial reference point.

You can locate Lithographic Stone B on a nearby bookshelf immediately adjacent to the puzzle door. Lithographic Stone C rests on top of a stack of old books situated on a shelf nearby. Lithographic Stone D is safely contained within a glass display case that must be smashed to retrieve the final piece.

Understanding the Puzzle Mechanics and Rules

Solving the lithographic door puzzle requires matching three distinct visual details for each slot. You must pay attention to the item symbol, the color of the icon, and whether the border forms a square or a hexagon.

A key mechanic to remember is that each stone plate can be flipped around to reveal a secondary symbol on its back. If a piece does not seem to fit any visible prompt, flipping the stone will display the matching icon and background color required.

Step-by-Step Lithographic Stone Solution

To successfully unlock the Bindery door, place Lithographic Stone D into the top slot so the red square with the shield icon faces outward. Next, insert Lithographic Stone A into the left slot showing the red hexagon with the helmet icon.

For the remaining positions, insert Lithographic Stone C on the right side to display the blue square with the sword icon. Finally, place Lithographic Stone B in the bottom slot with the blue hexagon armor symbol visible. Once all four pieces align correctly, the mechanism will trigger and open the path forward.

Rewards and Next Steps in the Castle
