This simple dexterity game has become quite popular with casual gamers. The whole game is stacking a tower of blocks removing one at a time, stacking that piece on top, making the tower even taller. Eventually someone will pull out a block that is supporting alot of weight and the tower will tumble down. This is one game that is entertaining for a while but if you have more than two players it has no definite winner, only a definite loser.
Like other games that become popular with casual gamers, Jenga has also spawned some spin-offs. Check out Jenga: Truth or Dare and Uno Jenga when this one gets old.
Jenga: Truth or Dare is a new variation of an old game. In this version the blocks are colored red, black and natural tan. Black blocks have a question written on them, while Red has Dares, and Tan blocks are blank allowing players to write there own "truth or dare" on the block. When a player pulls out a block they must tell a "Truth" or do the "Dare" that is on that block before stacking the block. If the player doesn't do it, he/she must pull another block after that and has no choice but to do that "Truth or Dare." If the block is Tan and has nothing on it the player can just stack the block like in regular Jenga.
Here's another variation to this game, which seems a little more twisted than Truth or Dare is - instead of writing on the Tan blocks, just make a drinking game out of it by taking a drink for each Tan block pulled. Of course the loser of this version would also take a drink - meaning that if the loosing block was Tan, that player would take one drink for the block and another for knocking down the tower.
