Jenga is a game of physical skill created by Leslie Scott. Players take turns removing one block at a time from a tower constructed of 54 blocks. Each block removed is then placed on top of the tower, creating a progressively taller and more unstable structure.

The name jenga is derived from kujenga, a Swahili word which means "to build".The game uses 54 wooden blocks. The length of each block is three times its width, and the height is approximately half its width. To start the game you need to build a tower with a height of 18 floors. Each floor consists of three blocks, laid close and parallel to each other. Blocks of each next floor are laid perpendicular to the blocks of the previous floor.

After the tower is built, players begin to walk. The first to walk is the one who built the tower. The move in jenge consists of pulling one block from any level (except the one directly under the unfinished upper) of the tower and its subsequent placement at the top of the tower so that it can be completed (you can not finish the floors under the incomplete upper level). Only one arm is allowed to extract the block;
