Build a casino with one huge circular central hall and exactly four huge, straight hallways attached at the north, south, east, and west sides. Align every hallway to the Minecraft world grid. The hallways must extend outward from the circular room; none should cross through it or run diagonally. Add one entrance on the side of the central hall. Floor: Use one solid, uniform black floor throughout the central hall and all four hallways. Use black concrete for every floor block. Do not add borders, patterns, stripes, tiles, spots, gradients, or any other floor color. Walls and details: Use deep red for large wall sections, sandstone for the pillars, and gold blocks only for a few large, simple decorative accents. Keep each color in clean, solid areas. Do not scatter blocks or create speckle
