Abstract: A method of playing a multiplayer game comprises steps of providing a plurality of blocks and providing a plurality of viewable images. Each of the images represents a configuration of at least two of the plurality of blocks oriented in a particular manner with respect to each other. The method also comprises designating at least one game player of a first team to serve as an instructor of the first team. The instructor of the first team views the configuration of a first one of the images and then provides instructions regarding how to assemble the configuration shown in the first one of the images while at least one other of the game players of the first team attempts to construct at least part of the configuration out of the blocks using the instructions.
