The Bedlam Cube, rebranded as the "Crazee Cube" in 2009, is a dissection puzzle invented by British puzzle expert Bruce Bedlam. The cube consists of 13 geometric pieces. Of the 13 pieces, seven can be rotated into 24 possible positions, five can be rotated into 12 possible positions, and one can be rotated into three possible positions. The objective of the Bedlam Cube is to assemble the pieces -- four red, five yellow and four blue -- into a 4x4x4 cube. There are a total of 19,186 combinations to solve the puzzle.

Place piece No. 7, "red tall-L-bump," in the bottom-right corner. Position piece No. 1, "red flat-X-plus," to the left of piece No. 7.

Place the "yellow twisted-Z," piece No. 8, in the upper-left corner. Place the "red bent-W-tip," piece No. 3, on top of No. 7 in the bottom-right corner. Place the "yellow folded-X," piece No. 4, in the top-right corner. Place the "red z-bump," piece No. 5, to the right of No. 4.

Select piece No. 12, called the "yellow squiggle," under piece No. 1, "red flat-X-plus." Select piece No. 0, labeled "blue flat-R," and snap into place in the top-right corner above the "yellow folded-X," piece No. 4.

Place the "yellow L-bump-end," piece No. 9, in the bottom-left corner above the "yellow twisted-Z, piece No. 8. Select the "blue bent-R-tip," piece No. 11, and place in the lower-left corner. Place "yellow bent-T," piece No. 6, in the top-right corner. Select the "blue flat-R, No. 0, and place it top left. Place the last remaining piece, No. 2, "yellow flat-W," on top and you have solved the Bedlam Cube.
