Bring the fun of a backyard party, tailgate, or family gathering to new heights with this giant‐sized stacking game. Giant Tumbling Timbers includes 56 smooth, sanded pine blocks (each approximately 1.5″ × 2.5″ × 7.5″) that are stacked in 19 levels – with two extra blocks to give the tower a little extra height. fungameselect.com
The game starts with a tower about 2.5 feet tall and for skilled players it can grow well over 4 feet tall during play. 
Here’s how to play:
Two or more players take turns. Best Buy
On your turn you must remove one block from anywhere below the highest completed level of the tower using only one hand, and then place that block on top to extend the tower’s height. 1800baskets.com
The goal is to be the last player to successfully place a block without causing the tower to tumble. 
The set is built for indoor or outdoor use — perfect for lawn games, camping, BBQs or even receptions. The blocks are made of sustainably-sourced pine wood, hand-cut and sanded for a smooth finish. A nylon carrying case is included for storage and transport.
