How to Play Siga

By Jaques of London · Est. 1795 · Updated 2026-08-17

Siga is a traditional 2-player abstract strategy game played on a chequered or grid board using opposing sets of pieces. Each player moves pieces forward according to fixed rules, capturing enemy pieces by landing on or displacing them. The game rewards careful planning: every move either creates an opportunity or opens a weakness.

Players value Siga for its short play time and the genuine tension it produces even in a compact game. It is most commonly found in North Africa and parts of the Middle East, where it is played informally on hand-drawn boards as often as on manufactured sets.

A little history

The precise origins of Siga are unclear. It is documented as a traditional game of North Africa, with recorded play in Egypt, Libya, and surrounding regions. Scholars of traditional games group it among a wider family of displacement and capture games found across the African and Arab worlds, but the exact lineage and date of origin are not established in the historical record. The game has been passed down through informal play rather than written rulebooks, which means regional rule variations exist alongside the core form described here.

Setting up

1. Place the board between both players so that the longer axis runs between you.
2. Each player takes 12 pieces of their chosen colour.
3. Player 1 places all 12 pieces on the two rows nearest to them, filling every square in those rows.
4. Player 2 mirrors this, filling the two rows nearest to them.
5. The two central rows are left empty at the start.
6. Decide who moves first, traditionally by mutual agreement or by lot.

How to play

1. Players alternate turns throughout the game; you may not pass your turn.
2. On your turn, move one of your pieces exactly one square in any direction: forward, backward, left, or right. Diagonal moves are not permitted.
3. A square occupied by one of your own pieces cannot be entered.
4. To capture an opponent's piece, move your piece into the square it occupies. Remove the captured piece from the board immediately.
5. Capturing is not compulsory: you may make a non-capturing move even when a capture is available.
6. There is no chain or multiple capture in a single turn; only one piece may be captured per move.
7. A piece that reaches the far edge of the board (the opponent's back row) has no promotion or special status: it continues to move by the same rules.
8. Play continues until one player has captured all of the opponent's pieces, or until one player has no legal move available on their turn.

Winning and scoring

The game is won when you capture all of your opponent's pieces, leaving them with none remaining on the board. Alternatively, if it is your opponent's turn and every one of their pieces is completely surrounded with no legal square to move into, you win immediately. There is no points-based scoring in standard Siga: the result is simply a win or a loss. In a match format, players typically agree a number of games in advance and the player who wins the majority takes the match.

The fine points

The most common dispute concerns whether capturing is compulsory. In standard Siga it is not: you are free to move anywhere legal regardless of available captures. If your group plays the compulsory-capture variant, agree this before the game begins so there is no ambiguity mid-play. When a piece could capture in more than one direction, the moving player chooses freely which capture to make.

Stalemate, where a player has pieces on the board but no square any of them can legally enter, is relatively rare but does occur on a crowded board. The standard ruling is that the stalemated player loses immediately, since they cannot fulfil their obligation to move. If pieces are reduced to a small number on each side and neither player can make progress, the game is declared a draw by mutual agreement; there is no automatic draw rule in the traditional form.

How to win more often

• Control the centre early: pieces in the middle rows have the greatest number of directions available and are harder to trap.
• Keep your pieces connected so that a neighbour can retake if one is captured; isolated pieces are easy targets.
• Count your opponent's escape squares before committing to an attack: a piece that looks trapped may have a route you have missed.
• Do not rush to advance all your pieces at once. A solid rear line prevents your opponent from wrapping around and cutting off your forward pieces.
• When ahead in material, simplify by trading pieces wherever the exchange is equal: the fewer pieces on the board, the harder it is for your opponent to recover.

Variations

Compulsory Capture

In this widely played variant, if any legal capture is available on your turn you must make one; you cannot choose a non-capturing move instead. When multiple captures are possible, you choose which to take. This single rule change makes the game considerably more tactical, as both players must constantly scan for forced captures that their opponent can exploit.

Smaller Board (4x5)

Played on a reduced 4x5 grid with 8 pieces per player placed across the two nearest rows, this version produces a faster, sharper game. The compressed space means confrontation is almost immediate and the game rarely lasts more than ten minutes. It works well as a quick introduction for younger players or for a tiebreaker game.

Diagonal Movement Allowed

Some regional traditions permit pieces to move diagonally as well as orthogonally, giving each piece up to eight possible directions rather than four. This makes mass captures less likely and shifts the game toward positional manoeuvring. Capturing still occurs by entering the opponent's square, and all other rules remain unchanged.

Three-Row Setup

Each player begins with pieces filling their three nearest rows rather than two, using an 18-piece set on an enlarged board. This extends the game significantly and allows for more complex formations. The additional pieces mean the opening phase lasts longer and mid-game tactics become richer, suiting players who find the standard game resolves too quickly.
