Giant Jenga rules

1. Find hard, level ground and clear the area around it.
2. Lay three blocks side by side to make a row. Lay the next three across them at 90 degrees. Repeat.
3. Build until you run out — Yard Games publishes 19 rows for its 56-block Giant and Large sets, and 18 rows for the 54-block 21-inch junior set.
4. Straighten the tower by running a flat hand down each face before you start.

That last step matters more than it sounds. Blocks that sit even slightly proud on one side put every subsequent pull off balance, and the game ends early for a reason nobody enjoys.

1. Players take turns. Order is however you like; alternate around the tower.
2. On your turn, remove one block from any complete row below the top row.
3. One hand only. This is the rule that makes the game hard and the one casual games abandon first.
4. Place the block on top, across the row below, to keep building.
5. Your turn ends when the block is placed and you have taken your hand off it.
6. Whoever makes the tower fall loses.

You may touch and test blocks to find a loose one, but once you have moved a block enough that it is clearly out of line, you have committed to it.

This is the dispute that ends giant Jenga games badly, and it is worth agreeing in advance. The standard convention:

• The tower has fallen when any block other than the one being placed comes off the tower. You do not wait for a full collapse.
• A block you knock and catch still counts as having come off.
• The block in your hand does not count — dropping the one you are placing is not a loss until it disturbs the tower.

The base game is a two-player game that a crowd watches. These variants make it a crowd game, which is what you bought a giant version for:

• Write on the blocks. Instructions, questions or forfeits on each block, revealed when it is pulled. It is the single most common modification and it turns the tower into an icebreaker — genuinely why these turn up at weddings. Note that writing on blocks is permanent.
• Two-tower race. Two teams, two towers, first to collapse loses. Doubles the number of people playing at once.
• Time limit. Ten seconds per turn. Removes the deliberation and makes a long game short, which is useful at a party.
• Non-dominant hand only. The best handicap we know of for a mixed group, because it costs an experienced player far more than a beginner.

The reach column is the one that decides whether a child actually plays. A tower's interesting phase is the endgame, and the endgame happens above the starting height. On the 2.5-foot set that means placing blocks at four or five feet — a game a child watches. On the 21-inch set, the same endgame is at their eye level.
