Things You'll Need
Instructions
Construct the raised platform for the ring. Use standard thickness bricks, and build your ring two to three LEGOs tall. You can use any combination of brick sizes to achieve a square, ideally about 14 circles long on each side. Try to use a single color of bricks, if possible, at least for the pieces visible on the sides of the ring.
Place the mat on the platform. If possible, use a single flat base piece the size and color of your platform -- 14 circles long on each side.
Mount the raised platform, if possible. If you have a single flat base piece larger than your ring -- ideally at least 16 circles long on each side -- mount your platform on this piece.
Construct the edges of the ring. Build posts at each of the four corners of the ring. Each post should be about two-by-two, and about three standard bricks tall. If you would like to use specialty pieces with hook extensions to mount LEGO rods for the ropes, you can. Otherwise, you can string twine, string, yarn or anything similar around the posts to create the ropes. Place at least two ropes around the ring.
Add your ladder. If you have a specialty LEGO fold-out ladder piece, use that. Otherwise, you can use two single-panel ladder pieces from any number of construction sets, fastened together at the top using a brick with hook extensions to snap onto the ladders' top beams.
Suspend the money case. You can simply tie the case to a string, and tie the string to any object above the ring. Or, for true authenticity, you can construct a post or posts from standard LEGOs outside the ring with an arm extending from it over the ring, and suspend the case from that.
Place your mini-figures in the ring. Make sure you have at least three or four mini-figures to contend for the money.
Brawl.
