Jenga is a Parker Brothers board game played with 54 wooden blocks. The blocks are stacked in a particular way and players take turns removing them from below the top level. The game ends when the tower falls; the last player to have successfully removed a block is the winner.
A similar game is being played in the video below with giant blocks and assorted Caterpillar equipment—though I’m sure it could also be done with other brands of machines. Is the video intended to promote the Cat brand? Of course it is, but that doesn’t make it any less fun to watch.
