==Notation==

===Board===
Each square is denoted using [[Algebraic notation (chess)|algebraic notation]].
:From ''player 1''{{'}}s perspective, columns are '''a''' to '''i''' from left to right and rows are '''1''' to '''9''' from bottom to top.
:From ''player 1''{{'}}s perspective, the near-left square is '''a1''', and the far-right square is '''i9'''.

===Pawns===

====Starting positions====
Two players:
:''Player 1''{{'}}s pawn starts on '''e1'''
:''Player 2''{{'}}s pawn starts on '''e9'''
Four players:
:''Player 1''{{'}}s pawn starts on '''e1'''
:''Player 2''{{'}}s pawn starts on '''a5'''
:''Player 3''{{'}}s pawn starts on '''e9'''
:''Player 4''{{'}}s pawn starts on '''i5'''

====Moves====
Each pawn move is defined by the new square occupied by the pawn.
:For example, if ''player 1'' moves their pawn from '''e1''' to '''e2''', ''player 1''{{'}}s move is denoted as '''e2'''.

===Walls===
Every wall touches four squares.
A wall move is denoted by the closest square to '''a1''', with a horizontal '''h''' or vertical '''v''' orientation.
:For example, a vertical wall between columns '''e''' and '''f''' and spanning rows '''3''' and '''4''' is denoted '''e3v'''.

===Formatting===
A game or series of moves is generally written in one of two ways.

#In columns, as player groups, preceded by the move number and a period:
#* Two player game:
#*:'''1. e2 e8'''
#*:'''2. e3 e7'''
#* Four player game:
#*:'''1. e2 b5 e8 h5'''
#*:'''2. e3 c5 e7 g5'''
#Horizontally:
#* Two player game:
#*:'''1. e2 e8 2. e3 e7'''
#* Four player game:
#*:'''1. e2 b5 e8 h5 2. e3 c5 e7 g5'''
Moves may be interspersed with commentary (annotations). When the game score resumes with ''player 2'', ''player 3'' or ''player 4''{{'}}s move, an ellipsis (...) fills the position of ''player 1''{{'}}s move, for example:

:'''3. e6h'''
::''Player 1'' places a wall to lengthen ''player 2''{{'}}s path.
:'''3... e3h'''
::''Player 2'' responds by placing a wall to lengthen ''player 1''{{'}}s path.

===Defined game positions===
A [[Forsyth–Edwards Notation]]-like record can define a particular game position:

<code>
[1] / [2] / [3.1] [3.2] [3.3*] [3.4*] / [4.1] [4.2] [4.3*] [4.4*] / [5]
</code>

# Vertical wall positions
# Pawn positions:
## Player 1 pawn position
## Player 2 pawn position
## Player 3 pawn position*
## Player 4 pawn position*
# Walls available:
## player 1 walls available
## player 2 walls available
## player 3 walls available*
## player 4 walls available*
