Identical in appearance to the Cluster Buster, the Improved Cluster Buster uses three dissimilar pairs of pieces making it a more difficult puzzle to both disassemble and assemble. There is only one solution with a minor variation. Making it from a single species of wood compounds the difficulty. Stewart made 10 in 1973. Number 49 in his numbering system.
