Hidden Information — Military Deception Game

Stratego

A two-player military game where all pieces are hidden — you don't know the enemy's ranks until you attack. The game that teaches intelligence gathering through controlled engagement and the art of deception.

Published by Jumbo Games, 1946 (Netherlands) 2 players — 10×10 grid, 40 pieces each Based on earlier French game L'Attaque (1909)

"In Stratego, the pieces you don't move tell your opponent as much as the ones you do."

— On passive information leakage

Origins & significance

Background

Stratego was published in the Netherlands in 1946 by Jumbo Games, based on the earlier French game L'Attaque patented by Hermance Edan in 1909. The game gained worldwide popularity when licensed by Milton Bradley in 1961 for the American market. Each player deploys 40 pieces — ranked from Marshal (highest) to Scout (lowest), plus Bombs and a Flag — all placed face-down so the opponent cannot see their ranks. Pieces are revealed only during attacks. Stratego has sold tens of millions of copies and remains the most popular hidden-information military game, influencing digital games from Fire Emblem to Advance Wars.

The strategic thesis

What Stratego teaches about strategy

Stratego is the only mainstream strategy game built entirely around information asymmetry. In Chess, you see everything. In Poker, you see nothing. In Stratego, you see the positions but not the identities — and you must discover what you're facing through the act of engaging. This makes every attack a dual-purpose operation: it achieves a tactical objective (capturing or losing a piece) but it also generates intelligence (revealing a rank).

→The central strategic question is never simply "should I attack?" but "is the intelligence I gain from this engagement worth the piece I might lose?" This is the strategy of probing, reconnaissance, deception, and the management of what your opponent knows about you — applicable to every competitive environment where information is hidden and must be discovered through action.

Strategic principles

01Your deployment is your first strategic decision — and your most important one.

Where you place each piece before the game begins determines your defensive structure, your offensive options, and the deception you present. Strong players design their deployment to protect the Flag, create layered defenses around Bombs, and position offensive pieces for maximum flexibility. The strategic lesson:

how you arrange your resources before the competition begins often matters more than how you use them during it. Preparation architecture is strategy.

02Every engagement is an intelligence operation.

When two pieces clash, both players learn something — the attacker discovers the defender's rank, and the defender knows the attacker was willing to risk that piece in that location. The strategic lesson:

every competitive interaction generates information for both sides. Before you act, consider not just whether you'll win the exchange but what your action reveals about your broader position.

03Scouts are your most strategically valuable pieces.

The Scout (rank 2, lowest combat value) can move any number of squares in a straight line. This makes it the perfect probe — expendable enough to sacrifice for intelligence, mobile enough to test multiple positions. The strategic lesson:

small, expendable investments that generate disproportionate information are among the most valuable strategic tools available. The cheap experiment that reveals market reality beats the expensive launch that assumes it.

04Bluff with piece behavior, not just placement.

A Miner (the only piece that can defuse Bombs) moved aggressively toward the enemy's back row signals "I know where your Flag is." A low-ranked piece advanced confidently toward strong positions signals "I'm high-ranked." The strategic lesson:

deception is not just about hiding information — it's about the false information you actively project through behavior. How you move tells a story. Make sure it's the story you want your competitor to believe.

05Protect your Miners — they are your only path to the Flag.

The Flag is typically surrounded by Bombs that destroy any attacking piece — except Miners. Losing all your Miners means you cannot capture the Flag regardless of how many other pieces you have. The strategic lesson:

identify which of your capabilities are irreplaceable — the ones without which victory is structurally impossible — and protect them above all others. Not every asset is equally critical. Know which ones you cannot afford to lose.

06Track everything your opponent reveals.

Each engagement reveals information that compounds over the game. The player who mentally maps discovered pieces, deduces unidentified ones by elimination, and uses this cumulative intelligence to guide later moves holds a decisive advantage. The strategic lesson:

information compounds. The strategist who records, synthesizes, and acts on accumulated intelligence over time outperforms the one who treats each encounter as isolated.

07The pieces you don't move reveal as much as the ones you do.

A piece that never moves is almost certainly a Bomb or a Flag. A piece that avoids engagement is probably weak. An immobile piece in the back row is either a trap or the objective. The strategic lesson:

inaction is itself a signal. In any competitive environment, what people don't do — the market they don't enter, the meeting they skip, the question they don't ask — tells you as much about their position as their visible actions.

What this game teaches

In business

Stratego teaches that in competitive environments where information is hidden — which describes virtually every business situation — the ability to gather, synthesize, and act on intelligence is the decisive advantage.

→Every customer interaction, every competitive encounter, every hiring interview reveals information — if you're paying attention.

→Use small, expendable probes (market tests, pilot programs, prototype launches) to discover reality before committing major resources.

→Track what you learn cumulatively — isolated data points are noise; accumulated intelligence is insight.

→Protect your irreplaceable capabilities above all others.

→And understand that your own actions are generating intelligence for competitors: everything you do in the market tells a story about your strategy.

→Make sure it's the story you intend to tell.

In life

Stratego teaches that people, like Stratego pieces, don't reveal who they are until you engage with them — and even then, you only learn what that specific engagement reveals.

→You cannot know someone's character from their appearance or their position.

→You learn it through interaction — through small tests, through shared experiences, through the accumulated evidence of how they behave across many situations.

→Don't bet everything on your first impression.

→Probe.

→Observe.

→Accumulate information.

→And remember: just as your opponent in Stratego watches how you move your pieces, the people in your life are drawing conclusions from your behavior too.

→Every action reveals something about you.

→Be intentional about what you show.

About the game

All pieces are hidden. Each player's 40 pieces are placed face-down, showing only the player's color. You cannot see your opponent's ranks until a piece engages in combat. This is the defining mechanic — everything flows from not knowing what you're facing.

Higher rank wins combat. When two pieces clash, the higher-ranked piece survives and the lower-ranked one is removed. Equal ranks destroy each other. The single exception: the Spy (lowest rank) defeats the Marshal (highest rank) if the Spy attacks first.

Bombs destroy everything except Miners. Bombs don't move but destroy any piece that attacks them — except the Miner, who defuses them. This creates the primary defensive structure of the game: Flags protected by Bombs, accessible only to Miners.

The board has two impassable lakes. The center of the 10×10 board features two 2×2 lakes that cannot be crossed. These natural chokepoints force movement into defined corridors, creating ambush opportunities and limiting the Scout's long-range movement.

Memory and deduction compound over the game. As pieces are revealed through combat, the information landscape shifts. Advanced players mentally track every revealed piece and use elimination logic to deduce the identity of pieces that haven't yet been encountered.

The goal

Capture your opponent's Flag. Each player deploys 40 pieces face-down on their half of the board. Pieces are revealed only when they attack or are attacked. The first player to capture the enemy Flag — or to eliminate all the opponent's movable pieces — wins.

Rules of the game

01

Setup: Each player arranges 40 pieces face-down on their half of the 10×10 board (first 4 rows). Pieces: 1 Marshal, 1 General, 2 Colonels, 3 Majors, 4 Captains, 4 Lieutenants, 4 Sergeants, 5 Miners, 8 Scouts, 1 Spy, 6 Bombs, 1 Flag.

02

Movement: Players alternate moving one piece per turn. Most pieces move one square in any cardinal direction (no diagonals). Scouts can move any number of squares in a straight line. Bombs and Flags cannot move.

03

Combat: Move your piece into a square occupied by an opponent's piece. Both pieces are revealed. Higher rank wins; loser is removed. Equal ranks: both removed. Spy beats Marshal only if Spy initiates the attack.

04

Bombs: Any piece that attacks a Bomb is destroyed (both are removed). Exception: Miners defuse Bombs — the Bomb is removed, the Miner survives and occupies the square.

05

Lakes: Two 2×2 zones in the center of the board are impassable. No piece may enter or cross these squares.

06

Victory: Capture the opponent's Flag to win. If a player cannot move any piece on their turn (all movable pieces eliminated), they also lose.

Bottom line

Stratego teaches the strategy of intelligence and deception — that in environments where you cannot see what you're facing, the ability to probe, gather, synthesize, and act on information is worth more than raw strength. It is the game that proves: what you know about your opponent — and what they don't know about you — determines the outcome more than the forces either of you actually possess.
