Thanks to Backyard Games, we have a super-sized version of the classic game everyone knows and loves.

SCROLL DOWN TO BE IN THE DRAW TO WIN A GIANT TUMBLING TOWER, WORTH $149

Attempt to build the tower as high as possible without toppling it over. The player that removes a block and causes the tower to fall, loses. 
The game includes 54 pine wood blocks, and a carry case – handy for taking it over to a mates' place, or to your next picnic.
