ABSTRACT:
A cubic puzzle includes eight identical elementary pieces. Each elementary piece is composed of eight identical blocks. The lower layer has a first, a second, and a third block linearly connected to a side face of each other and a fourth block transversely and securely connected to a side of the third block. The upper layer has a fifth block securely connected to a side of a sixth block, wherein the fifth block is formed on top of the first block, and a seventh block securely connected to a side of an eighth block, wherein the seventh block is formed on top of the fourth block. A position relationship between the sixth block and the fifth block and the seventh block to the eighth block corresponds to a position relationship between the fourth block and the third block.
