Reconstructing Ancient Roman Board Games: Ludus Latrunculorum Rules

The Lost Board Games of Rome

When we picture daily life in ancient Rome, we often think of gladiators, aqueducts, and political intrigue. But for the average Roman citizen, evenings were spent much like ours: gathered around a board game. Among the most popular was Ludus Latrunculorum, or the Game of Little Soldiers. Unlike dice games like alea, which were often associated with gambling and frowned upon by moralists, latrunculi was a game of pure strategy, akin to chess. Its exact rules were lost to time, but through archaeological finds and literary references, historians have pieced together a plausible reconstruction. This article offers a practical guide to playing a historically grounded version of the game, so you can enjoy a genuine piece of ancient leisure.

What We Know from the Archaeological Record

The earliest known reference to latrunculi appears in the works of the Roman author Varro (116–27 BCE), who mentions it alongside other games. The most famous physical evidence is the board carved into the floor of the Basilica Julia in the Roman Forum, dating from the 2nd century CE. This board has a grid of 8×12 squares, though other boards found across the empire vary from 7×7 to 9×10. Pieces, called latrones (mercenaries) or calculi (stones), were typically made of glass, bone, or terracotta. In 2014, a cache of 600 glass gaming pieces was unearthed in Hadrian's Villa, suggesting the game's popularity among the elite. The poet Ovid even mentions the game in his Ars Amatoria, advising young men to play it to impress their beloveds.

Core Rules: A Scholarly Consensus

While no rulebook survives, scholars like R.C. Bell and H.J.R. Murray have proposed reconstructions based on a passage from the late Roman author Macrobius, who describes a game called latrunculorum played with pieces that move like a rook in chess. The most widely accepted rules are:

• Board: typically 8×8 or 8×12, but any rectangular grid works.
• Pieces: each player has an equal number, often 30 on a 12×8 board.
• Movement: pieces move orthogonally any number of unoccupied squares, like a rook.
• Capture: a piece is captured if it is sandwiched between two enemy pieces along a row or column, with the capture being made by the player who completes the trap.
• Objective: to immobilize or capture all enemy pieces, or to reduce them to a point where they cannot move, akin to checkmate.

This simple yet deep system creates a game of tactical positioning, similar to a cross between chess and checkers.

Setting Up Your Game

To play a historically plausible version, you'll need a board and pieces. You can buy a reproduction or make your own: draw a 12×8 grid on a piece of leather or wood, and use coins or pebbles as pieces. Each player starts with their pieces placed on the first two rows on their side. Some reconstructions place pieces on every square of the first row and alternating squares on the second. For our recommended rules, use 24 pieces per player on a 12×8 board, arranged in three rows of eight. This gives a full board with room for maneuver, as described by the poet Ausonius in his poem about the game.

Step-by-Step Gameplay

Here is a step-by-step guide to a standard game, based on the most common reconstruction:

1. Place the board between you and your opponent, with each player having a full row of pieces on their side.
2. Decide who moves first by lot, as was common in antiquity.
3. On your turn, move one of your pieces orthogonally any number of empty squares. You may not jump over any piece, friend or foe.
4. Capture an enemy piece by trapping it between two of your own pieces in a straight line. The capture is made by the player who moves to complete the trap, and the trapped piece is removed immediately.
5. You may also capture multiple pieces in one move if you trap more than one at the same time (a rare but possible occurrence).
6. The game ends when one player has lost all pieces or cannot make a legal move. That player loses; the opponent wins.
7. Alternatively, some players play to a fixed number of captures (e.g., first to capture 10 pieces wins).

This simple set of rules yields a surprising strategic depth, with players constantly setting up traps and blocking enemy moves.

Strategy: Lessons from Ancient Tactics

While we have no ancient strategy guides, we can infer tactics from the game's nature. Because pieces move like rooks, controlling the center of the board is crucial. A common opening is to advance your central pieces to dominate the four central columns. Capturing requires cooperation between two pieces, so keeping your pieces connected is vital. Avoid creating isolated pieces that can be easily trapped. Also, beware of the 'duo' formation: two of your pieces adjacent to each other can form a barrier that is hard to break. In a 2018 analysis by game historian Ulrich Schädler, he noted that the game likely involved a 'dux' or leader piece, similar to a king, but this is speculative. For our practical version, we omit it, but you can add a 'dux' for a variant: if your dux is captured, you lose.

Comparing Reconstructions: Bell vs. Murray

Two major reconstructions exist, and they differ in a few key details. The following table summarizes the differences for the serious player:

Bell's version is quicker and more aggressive, while Murray's is more positional and longer. For beginners, we recommend Bell's 8×8 version, as it is easier to grasp and fits on a standard chessboard. For a more authentic feel, use Murray's larger board, which matches the Basilica Julia find.

Where to Play Today

You can find digital versions of latrunculi on platforms like Board Game Arena or as mobile apps, but playing with physical pieces adds a tactile connection to history. Many museums, such as the Roman-Germanic Museum in Cologne, sell reproduction sets. Alternatively, you can join online communities of historical game enthusiasts, such as the Ludus Latrunculorum Forum, where players discuss strategies and share variant rules. If you are a teacher, this game is an excellent way to introduce students to Roman daily life, as it requires no language skills and can be played in minutes.

The Enduring Appeal of Latrunculi

Ludus Latrunculorum is more than a historical curiosity; it is a genuinely fun and challenging game that deserves a place in your game night rotation. Its rules are simple enough to learn in a few minutes, yet it offers strategic depth that can take years to master. By playing it, you are participating in a tradition that spans two millennia, connecting you to the Romans who enjoyed the same mental battles. So gather some tokens, draw a grid, and see if you can outwit your opponent like a cunning Roman general. The past is not so far away after all.
