Structural Risk — Dexterity & Nerve Game
Jenga
A game about pulling blocks from a tower without causing it to collapse — even as you build it higher. The only game where every player contributes to the same structure and the same destruction.
Created by Leslie Scott, 1983
2+ players — 54 wooden blocks
From Swahili: kujenga — 'to build'
"The tower doesn't care who built it or who weakened it. It only knows physics. And physics doesn't negotiate."
— On Jenga as a model of systemic risk
Origins & significance
Background
Jenga was created by Leslie Scott in the early 1970s, based on a stacking game she played with her family in Ghana using hand-cut wooden blocks. She first sold it commercially in 1983 at the London Toy Fair. The name derives from the Swahili word kujenga, meaning "to build." Over 100 million copies have been sold worldwide. Jenga is unique among strategy games in that all players share and modify a single structure — there are no separate territories, armies, or hidden information. Only the tower.

The strategic thesis
What Jenga teaches about strategy
Jenga encodes a truth that most strategy frameworks ignore: most systems are shared, and most collapses are collective. Unlike games where you build your own position and attack others, in Jenga every player contributes to the same increasingly fragile structure.
→You inherit the instability everyone before you created — and you leave a more precarious situation for everyone after. The strategic lesson is not about how to win a competition but about how to assess and manage risk in systems where every participant is simultaneously building and undermining the same foundation.
→This is the strategy of organizations, markets, ecosystems, and relationships — shared structures where individual actions create collective consequences.
Strategic principles
01Read the system before you commit.
The best Jenga players test multiple blocks with light touches before choosing. Each block tells you something — how much weight it bears, how the tower will shift. The strategic lesson:
never commit to a move until you've assessed the structural consequences. The first option you see is rarely the best one.
02The risk is individual but the system is shared.
Every player weakens the tower for the next. The question is not just "which move is safest for me?" but "which move leaves the worst situation for my opponents?" The strategic lesson:
in shared systems, your actions affect everyone. The person who understands second-order effects — what their move does to the next player's options — holds an invisible advantage.
03Small margins determine catastrophe.
The difference between a successful pull and a collapse is often millimeters. A trembling hand collapses more towers than a bad choice. The strategic lesson:
in high-stakes situations, execution precision matters as much as strategic selection. The right decision poorly executed produces the same result as the wrong decision.
04The game gets harder the longer it runs.
Early moves are relatively safe. Middle moves require judgment. Late moves require nerve. The strategic lesson:
every system has a lifecycle. The strategies that work early — when there's margin for error — are not the strategies that work late, when every action is existential.
05Sometimes the best move makes your opponent's move impossible.
Advanced players remove blocks that leave the tower standing but in a configuration where the next player faces only terrible options. The strategic lesson:
strategic advantage isn't only about improving your own position — it's about shaping the decision landscape your competitors face.
06The person who collapses the tower isn't necessarily the one who caused the collapse.
The fatal move is usually the last in a long chain of destabilizing decisions made by everyone. The strategic lesson:
systemic failures are rarely caused by a single actor. They are the accumulated result of many individually "safe" decisions that collectively exceeded the system's tolerance. The question is whether you're the one inheriting the impossible position or the one who created it three turns ago.
What this game teaches
In business
Every organization is a Jenga tower.
→Every cost cut, restructuring, departure of a key person, or deferred maintenance removes a block.
→The question is never whether the structure will become unstable — it always does.
→The question is whether you're the one removing the load-bearing block or the one who inherits the impossible position.
→Strategic leaders assess structural risk before making changes and understand that the most dangerous removals are the ones that look safe on the surface — the "small" cost cuts, the "minor" reorganizations, the "temporary" compromises that permanently weaken the foundation.
→The Jenga principle for business: before you remove anything from a system, understand what it's supporting.
In life
Life accumulates instability the way a Jenga tower does — small stresses, deferred decisions, ignored problems, minor compromises.
→Each one is survivable alone, but they compound.
→The person who regularly assesses their load-bearing structures — health, key relationships, financial foundations, mental wellbeing — and reinforces them before they become critical is playing Jenga well.
→The person who keeps pulling blocks without checking the tower is building toward a collapse they won't see coming.
→Jenga's deepest life lesson: the collapse never feels sudden to the tower.
→It feels sudden only to the person who wasn't paying attention to the accumulating instability.
About the game
Every player shares the same structure. There are no separate territories or opposing forces. One tower. Every move changes it for everyone. This is the rarest dynamic in strategy games — pure collective systemic risk.
The tower grows taller as it grows weaker. Each removed block makes the structure more precarious while simultaneously extending its height. Progress and fragility are linked — you cannot advance without increasing risk.
Information is physical, not hidden. You can see and touch the tower. The wobble of a block under your fingertip is real-time intelligence about structural load. Reading the system requires tactile observation, not abstract analysis.
Nerve determines as much as knowledge. A shaking hand collapses towers that would have survived a steady one. The ability to execute under pressure — while everyone watches — is the decisive skill.
There is no winning strategy — only a less-losing one. You cannot build toward victory in Jenga. You can only survive longer than your opponents by making better risk assessments and steadier moves.
The goal
Remove a block from the tower and place it on top without causing the tower to fall. The last player to successfully complete a move before the collapse wins. Players take turns removing one block at a time from any level below the highest completed layer and stacking it on top.
Rules of the game
01
Setup: Stack 54 blocks in alternating layers of 3, each layer perpendicular to the one below. This creates an 18-layer tower.
02
Turns: Players take turns removing one block from any level below the highest completed layer. Only one hand may be used at a time.
03
Placement: The removed block must be placed on top of the tower, completing or starting a new layer. Each new layer alternates direction.
04
Testing: Players may tap or push blocks to test them before committing. Once a block is pushed fully out, the player must use that block.
05
Collapse: The player who causes the tower to fall — or causes any block to fall from the tower other than the one being removed — loses.
06
Winning: The last player to successfully remove and place a block before the collapse wins.
Bottom line
Jenga teaches the strategy of shared systemic risk — that the structures we depend on are weakened by every participant, that small removals compound into catastrophic instability, and that the collapse always comes as a surprise only to those who weren't reading the tower. It is the game that asks the most uncomfortable strategic question: are you building, or are you just pulling blocks and hoping someone else is left holding the tower?
