Stratego

All movable pieces, with the exception of the Scout, may move only one step to any adjacent space vertically or horizontally (but not diagonally).[4]^{: Movement:2} A piece may not move onto a space occupied by a like-color piece.[4]^{: Movement:4, 5} Bomb and Flag pieces are not moveable.[4]^{: Movement:7} The Scout may move any number of spaces in a straight line (such as the rook in chess).[4]^{: Movement:8} In the older versions of Stratego the Scout could not move and strike in the same turn;[4]^{: Movement:8}[7] in newer versions this was allowed.[8] Even before that, sanctioned play usually amended the original Scout movement to allow moving and striking in the same turn because it facilitates gameplay.

No piece can move back and forth between the same two spaces for more than three consecutive turns (two square rule), nor can a piece endlessly chase a piece it has no hope of capturing (more square rule).[4]^{: Movement:10}

When a player wants to attack, they "strike" by touching an opposing piece with their piece or by moving it onto the square the opposing piece occupies. Both players then reveal their piece's rank; the weaker piece (see exceptions below) is removed from the board.[4]^: Attack:5 If the engaging pieces are of equal rank, both are removed.[4]^: Attack:7 A piece may not move onto a square already occupied unless it attacks. The original rules also contained a provision that following a strike, the winning piece immediately occupies the space vacated by the losing piece.[lower-alpha 1][4]^: Attack:6

Two pieces have special attack powers. One special piece is the Bomb which only Miners can defuse. It immediately eliminates any other piece striking it without being destroyed itself.[4]^{: Attack:10} Each player also has one Spy, which succeeds only if it attacks the Marshal or the Flag. If the Spy attacks any other piece, or is attacked by any piece (including the Marshal), the Spy is defeated.[4]^: Attack:9

Competitive play does not include recording the game, unlike chess. The game is fast-paced, no standard notation exists, and players keep their initial setups secret, so recording over-the-board games is impractical.

However, digital interfaces such as web-based gaming interfaces may have a facility for recording, replaying and downloading the game. Those interfaces use an algebraic-style notation that numbers the rows ('ranks') 1 to 10 from bottom to top and the columns ('files') A to J from left to right. Alternately, a few interfaces designate the files as A to K, omitting 'I'. Moves are recorded as source square followed by destination square separated by a "-" (move) or "x" (strike). Revealed pieces on strikes precede the square designation, and may be by either rank name or rank number for brevity, for example "major B2xcaptain B3". The bottom half of the board is by default considered to be the 'red' side, and the top half the 'blue' side.

Unlike chess, Stratego is a game of incomplete information. In addition to calculated sequences of moves, this gives rise to aspects of battle psychology such as concealment, bluffing, lying in wait and guessing.

There are seven immobile pieces – six Bombs and one Flag – and 33 mobile pieces per player. They can move to the adjacent square in horizontal or vertical direction, with exception of the Scout, which moves any distance. From highest rank to lowest the pieces are:

US / EU Rank	"Classic" US Rank	Piece	Count per player	Special properties
B	B	Bomb	6	Immovable; any piece attacking a Bomb is removed from the game, unless the attacking piece was a Miner
10	1	Marshal	1	Most powerful piece, but vulnerable to capture by an attacking Spy
9	2	General	1
8	3	Colonel	2
7	4	Major	3
6	5	Captain	4
5	6	Lieutenant	4
4	7	Sergeant	4
3	8	Miner	5	Can defuse (i. e. capture) Bombs
2	9	Scout	8	Can move any distance in a horizontal or vertical straight line without leaping over pieces or lakes; originally unable to move and attack in the same turn,[7] later changed to allow movement and attack.[8]
1	S	Spy	1	Weakest piece, captured by any other attacking piece, but an attacking Spy can capture the Marshal
F	F	Flag	1	Immovable; capturing the opponent's Flag wins the game

The higher ranked piece always captures the lower, except when stated otherwise. When a piece attacks another piece with equal rank, both are removed.[7][8]

In the original versions published in the United States, the ranks were numbered with the most powerful Marshal piece ranked at 1, then numbers ascending as power fell until Scout was 9, and the Spy was not numbered but designated S.[7] In 2000, this was inverted, with the Marshal ranked as 10, descending to 2 for the Scout, and the Spy ranked with number 1.[8] "Classic" versions have been released since then with the lower number strongest, as in prior versions of the game.[7]

Variant versions of the game have a few different pieces with different rules of movement, such as the Cannon, Archer (possibly a different name for the Cannon), Spotter, Infiltrator, Corporal and Cavalry Captain. In one version, mobile pieces are allowed to "carry" the Flag. In some variants such as Stratego Waterloo and Fire and Ice Stratego, all or most of the pieces have substantially different moves.

Gunjin Shogi (23-piece)

Japanese Military Chess (Gunjin Shogi) has been sold and played since as early as 1895, although it is not known by whom and when it was invented.[9]^{: 129–130} Dr. Chiristian Junghans reported this game in Monatshefte magazine in Germany in 1905. It seems, only after reading his article, Julie Berg took out a patent on a war game in London and Paris in 1907.[10] Similarly, Hermance Edan took a patent for L'attaque game in 1909[11] and sold them in 1910.[9]^{: 154–158}

The main differences between Gunjin Shogi and Stratego are:

• Gunjin Shogi needs a referee to resolve the battles of the pieces, which are kept face-down throughout the game.[12]
• The Flag is placed only on the headquarters and a player who successfully occupied the headquarters of the opponent shall win the game.
• There are no Scout pieces. The Engineers and Spy have the same movement as the Scouts in Stratego.
• Only flag and senior officers can occupy the opponent's headquarters.
• Engineer (analog of miner) can remove mines and tanks.

There are at least three different versions of Gunjin Shogi, distinguished by the number of pieces controlled by each player as well as the size of the board. The 23- and 31-piece versions are similar, influenced by the technology of World War I, and the 25-piece version is a more recent development, incorporating technologies developed during World War II.[12]

In nearly its present form Stratego appeared in France from La Samaritaine in 1910, and then in Britain before World War I, as a game called L'Attaque.[13][14] Historian and game collector Thierry Depaulis writes:[15]

It was in fact designed by a lady, Mademoiselle Hermance Edan, who filed a patent for a "jeu de bataille avec pièces mobiles sur damier" (a battle game with mobile pieces on a gameboard) on 1908-11-26. The patent was released by the French Patent Office in 1909 (patent #396.795). Hermance Edan had given no name to her game but a French manufacturer named Au Jeu Retrouvé was selling the game as L'Attaque as early as 1910.

The French patent has 36 pieces for each player and also has a slightly different board layout, but it introduced the same hierarchical rules of attack and movement followed by modern versions of the game.[11] Depaulis further notes the 1910 version had two armies, divided into red and blue colors. The rules of L'attaque were basically the same as for the game we know as Stratego. It featured standing cardboard rectangular pieces, color printed with soldiers who wore contemporary (to 1900) uniforms, not Napoleonic uniforms. In papers of her estate, Ms. Edan states that she developed the game in the 1880s.[15]

The publishing rights for L'Attaque were acquired for the United Kingdom by game maker H.P. Gibson and Sons in 1925,[16] retaining the French name through at least the 1970s.[17][18] Gibsons also produced several modified forms of the game, at least one of which predates the acquisition of the rights:

• Dover Patrol – a naval warfare game on a board of 12×8 squares devised by Harry A. Gibson in 1911, but very similar to L'Attaque (and hence Stratego)
• Aviation (game) – an air battle variation designed by Harry Gibson in 1925, with a variant called Battle of Britain sold in the 1970s
• Tri-Tactics – a game combining land, sea and air warfare on a 12×12 board, with 56 pieces per person, dating from 1932, evolved from the above games.[19]

In 2019, Gibsons released a 100th anniversary edition of L'Attaque. This edition included both the original and modern rules.[20]

Stratego was created by Dutchman Jacques Johan Mogendorff sometime before 1942. The name was registered as a trademark in 1942 by the Dutch company Van Perlstein & Roeper Bosch N.V. (which also produced the first edition of Monopoly). After WW2, Mogendorff licensed Stratego to Smeets and Schippers, a Dutch company, in 1946. Hausemann and Hotte acquired a license in 1958 for European distribution, and in 1959 for global distribution. After Mogendorff's death in 1961, Hausemann and Hotte purchased the trademark from his heirs, and sublicensed it to Milton Bradley (which was acquired by Hasbro in 1984) in 1961 for United States distribution. It is introduced to the people of the United States as, "the American version of the game now popular on the Continent."[21] In 2009, Hausemann and Hotte was succeeded by Koninklijke Jumbo B.V. in the Netherlands.

The modern game of Stratego, with its Napoleonic imagery, was originally manufactured in the Netherlands. Pieces were originally made of printed cardboard and inserted in metal clip stands. After World War II, painted wood pieces became standard.[22] Starting in the early 1960s all versions switched to plastic pieces. The change from wood to plastic was made for economical reasons, as was the case with many products during that period, but with Stratego the change also served a structural function: Unlike the wooden pieces, the plastic pieces were designed with a small base. The wooden pieces had none, often resulting in pieces tipping over. This was disastrous for that player, since it often immediately revealed the piece's rank, as well as unleashing a literal domino effect by having a falling piece knock over other pieces. European versions introduced cylindrical castle-shaped pieces that proved to be popular. American editions later introduced new rectangular pieces with a more stable base and colorful stickers, not images directly imprinted on the plastic.

European versions of the game give the Marshal the highest number (10), while the initial American versions give the Marshal the lowest number (1) to show the highest value (i.e. it is the #1 or most powerful tile). More recent American versions of the game, which adopted the European system, caused considerable complaint among American players who grew up in the 1960s and 1970s. This may have been a factor in the release of a Nostalgic edition, in a wooden box, reproducing the Classic edition of the early 1970s.

Electronic Stratego was introduced by Milton Bradley in 1982. To promote the release, the company hired two actors to play Ronald Reagan and Leonid Brezhnev, who played a match at the New York Public Library Main Branch.[23]

It has features that make many aspects of the game strikingly different from those of classic Stratego. The board is 8 wide by 10 squares deep, instead of 10×10. The blocked "lake" areas are therefore 1×2 instead of 2×2. Each side has 24 pieces, instead of 40, deployed in the three rows closest to the player; instead of six bomb pieces, Electronic Stratego uses hidden bomb pegs.[24]

Each type of playing piece in Electronic Stratego has a unique series of bumps on its bottom that are read by the game's battery-operated touch-sensitive "board".[24]^: 7 When attacking another piece, the attacking player hits their Strike button, presses their piece and then the targeted piece: the game either rewards a successful attack or punishes a failed strike with an appropriate bit of music.[24]^: 22–25 In this way the players never know for certain the rank of the piece that wins the attack, only whether the attack wins, fails, or ties (similar to the role of the referee in the Chinese game of Luzhanqi).[25] Instead of choosing to move a piece, a player can opt to "probe" an opposing piece by hitting the Probe button and pressing down on the enemy piece: the game then beeps out a rough approximation of the strength of that piece.[24]^: 26–27

There are no Bomb pieces: Bombs are set using pegs placed on a touch-sensitive "peg board" that is closed from view prior to the start of the game.[24]^: 16–19 Hence, it is possible for a player to have their piece occupying a square with a bomb on it.[25] If an opposing piece lands on the seemingly empty square, the game plays the sound of an explosion and that piece is removed from play. As in classic Stratego, only a Miner can remove a Bomb from play.

The Scout is allowed to move diagonally, in addition to its usual horizontal and vertical moves. Again, as with the non-electronic Stratego, scouts are not allowed to jump over pieces.[24]^: 28–33

A player who successfully captures the opposing Flag is rewarded with a triumphant bit of music from the 1812 Overture.[24]^: 36[25]

In the late 1990s, the Jumbo Company released several European variants, including a three- and four-player version, and a new Cannon piece (which jumps two squares to capture any piece, but loses to any attack against it). It also included some alternate rules such as Barrage (a quicker two-player game with fewer pieces) and Reserves (reinforcements in the three- and four-player games). The four-player version appeared in America in 1997.

Starting in the 2000s, Hasbro, under its Milton Bradley label, released a series of popular media-themed Stratego editions.

Besides themed variants with substantially different rules, current production includes three slightly different editions: sets with classic (1961) piece numbering (highest rank=1), sets with European piece numbering (highest rank=10), and sets that allow substitution of one or two variant pieces such as Cannons, usually in place of scouts. Sets produced since 1970 or so have uniformly adopted the rule that scouts can move and strike in the same turn.

These have 10×10 boards, 40 pieces per side with classic pieces and rules of movement.

Official Modern Version: Also known as Stratego Original. Redesigned pieces and game art. The pieces now use stickers attached to new "castle-like" plastic pieces. The stickers must be applied by the player after purchase. Rank numbering is reversed in European style (higher numbers equals higher rank). Comes with an optional alternate piece, the Infiltrator.

Nostalgia Game Series Edition: Released 2002. Traditional stamped plastic pieces, although the metallic paint is dull and less reflective than some older versions, and the pieces are not engraved as some previous editions were. Wooden box, traditional board and piece numbering.

Stratego 50th Anniversary (2011) by Spin Master comes in both a book-style box and a cookie-tin-like metal box, with original new artwork, pieces and gameplay. It includes optional Cannons (2 per player) playing pieces.

Library Edition: Hasbro's Library Series puts what appears to be the classic Stratego of the Nostalgia Edition into a compact, book-like design. The wooden box approximates the size of a book and is made to fit in a bookcase in one's library. In this version, the scout may not move and strike in the same turn.

Michael Graves Design Stratego by Milton Bradley introduced in 2002 and sold exclusively through Target Stores. It features a finished wood box, wooden pedestal board, and closed black and white roughly wedge-shaped plastic pieces. Limited production, no longer available.

Stratego Onyx: Introduced in 2008, Stratego Onyx was sold exclusively by Barnes & Noble. It includes foil-stamped wooden game pieces and a raised gameboard with a decorative wooden frame. One-time production, no longer available.

Franklin Mint Civil War Collector's Edition: In the mid-1990s, Franklin Mint created a luxury version of Stratego with a Civil War theme and gold- and silver-plated pieces. Due to a last-minute licensing problem, the set was never officially released and offered for sale. The only remaining copies are those sent to the company's retail stores for display.

These have substantially different configurations and rules.

Ultimate Stratego: No longer in production, this version can still be found at some online stores and specialty gaming stores. This version is a variant of traditional Stratego and can accommodate up to 4 players simultaneously. The Ultimate Stratego board game contained four different Stratego versions: "Ultimate Lightning", "Alliance Campaign", "Alliance Lightning" and "Ultimate Campaign".

Science Fiction Version: Jumbo B.V. / Spin Master version of Stratego, common in North American department stores. The game has a futuristic science fiction theme. Played on a smaller 8×10 board, with 30 pieces per player. Features unique Spotter playing pieces.

Stratego Waterloo: For the bicentenary of the Battle of Waterloo in June 2015, the Dutch publishing group Jumbo published Stratego Waterloo. Instead of using ranks, the different historical units that had actually fought at the battle were added as Pawns (Old Guard, 95th Rifles...) – each with their own strengths and weaknesses.[29] The Pawns are divided into light infantry, line infantry, light cavalry, heavy cavalry, artillery, commanders and commanders-in-chief (Wellington and Napoleon). Instead of capturing the Flag, the players must get two of their pawns on the lines of communication of their opponent.

From highest rank to lowest the pieces are:

The higher ranked piece always captures the lower

Stratego Conquest: 1996, two- to four-handed game played on world map; alternate pieces cannons and cavalry

Stratego Fortress: A 3D version of Stratego featuring a 3-level fortress and mystical themed pieces and maneuvers

Fire and Ice Stratego: The Hasbro version called Fire and Ice Stratego has different pieces and rules of movement. The game features a smaller 8×10 board and each player has 30 magical and mythological themed pieces with special powers.

Hertog Jan, a Dutch brand of beer, released Stratego Tournament, a promotional version of Stratego with variant rules. It includes substantially fewer pieces, including only one Bomb and no Miners. Since each side has only about 18 pieces, the pieces are far more mobile. The scout in this version is allowed to move three squares in any combination of directions (including L-shapes) and there is a new piece called the Archer, which is defeated by anything, but can defeat any piece other than the Bomb by shooting it from a two-square distance, in direct orthogonal, or straight, directions only. If one player is unable to move any more of his or her pieces, the game results in a tie because neither player's Flag was captured.

These variants are produced by the company with pop-culture-themed pieces licensed from their respective owners:
