"Stack" pits five Cat® machines, including Excavators and Telehandlers, against a mountain of massive JENGA® blocks. The object of the game is for heavy equipment operators to remove and then reposition a stack of 27 JENGA® blocks one at a time, without toppling the structure — using only their Cat machines and attachments. #BuiltForIt
