According to Jenga rules, only one hand is supposed to be used by the players. The hand used to remove the block can only be used to replace it. At no point of time during this replacement can the hands be switched for any reason. Once a block has been successfully replaced, the player may use the other hand for the next round. Jenga rules allow the players to check for loosely placed blocks. This is helpful as it lets the players the comfort and luxury of confidently plucking out the block from the tower.
Sometimes, while removing a block, an adjacent block might get moved out of its position. In keeping with Jenga rules and instructions, this can be either replaced in the original position or left as such. The latter is considered only if it is determined that moving it any further will send the tower tumbling down. The turn of the first player ends with the successful replacement of the block or if the subsequent player touches the tower. If a move is not made within ten seconds of a round, the chance moves on to the next player.
This game needs loads of concentration. The player has to bear many things in mind before committing to remove a certain block from its place. Even a minor error can shift the balance of the blocks, and the tower might start shaking. To maintain the delicate balance is paramount. Jenga rules state that the game ends if the tower collapses or even if a piece or block falls out of its place. The winner is the player who is the last one to successfully complete a full stack of three blocks at the top. However, if all the concerned players decide so, the tower can be rebuilt and the game continued. This is very subjective though!
