Material
- Game board with 7 × 7 spaces
- 7 white and 7 orange pieces
- a sufficient number of sticks (about 50 “fences”)
Terminology
“Closed area”
A “closed area” is an enclosed area of spaces with exactly one piece inside representing the owner. There are no empty closed areas.
“Open area”
The “open area” is the area of spaces with more than one piece inside. There is almost always only one open area. At the beginning of the game the entire game board represents the open area, at the very end the open area is cleared away as only closed areas exist.
Objective
Players try to enclose the largest total area on the board.
Preparation
Players choose their color and take the corresponding 7 pieces. At the beginning players place one of their pieces on the center space on their side.
Both players can use the fences.
Play
Players take turns. White begins.
In each turn there are two possible actions, one of which a player must choose:
- Select a piece and build a fence
- Add a piece
A player who has no action available must pass their turn.
a) Select a piece …
A player selects one of their own pieces in the open area. This piece may now be moved.
Pieces move in a straight horizontal or vertical line (not diagonally) arbitrarily far, not on or over other pieces and not across sticks. During the movement the piece may change the direction once at a right angle.
… and build a fence
After an optional movement a fence must be built on one of the empty sides of the piece’s space. The outer edges of the board already represent a solid boundary, in the inside borders are formed with the fences.
When building a fence the following must always be considered: If an area is enclosed, there must be exactly one piece (of any color) inside. Creating an empty area is disallowed as well as enclosing another open area (with multiple pieces inside).
Note that a selection and/or move is not possible, if no fence can be built legally at the target space.
b) Add a piece
A player places a piece from their stock on an empty space which is exactly one move away from a friendly piece in the open area.
No fence is built in this action.
End of the game
The game ends as soon as the open area is cleared away by placement of a fence, i.e., only closed regions with single pieces inside exist. Players may still have pieces in their stocks.
Finally, players add the number of spaces of all areas they own.
The player with the highest total score wins.
Handicap
In the case where players of different strengths compete against each other, it may be agreed that the stronger player uses only 6 or even 5 pieces.

Larger Fendo boards (9 × 9 / 11 × 11)
Variants that step up from the standard game without changing its shape. The rules are identical to Fendo, with these changes:
- Board: 9 × 9 or 11 × 11 spaces
- Pieces: still 7 white and 7 orange pieces per player
- Objective: the first player to hold a majority of the board (41 / 61 spaces) wins; otherwise the end-of-game scoring is unchanged
Each player still places one starting piece on the centre space of their side.
Fendo moves combine piece movement with fence building. There are three types of moves:
Spawn a piece
Format: coordinate
Description: Place a new piece on an empty square.
Examples:
d4- Spawn a piece at the centera1- Spawn a piece in the bottom-left cornerg7- Spawn a piece in the top-right corner
Build a fence in place
Format: coordinate + direction
Description: Build a fence from the specified square in the given direction without moving the piece.
Directions:
n- North (up)e- East (right)s- South (down)w- West (left)
Examples:
d4n- Build a fence north from d4a1e- Build a fence east from a1g7w- Build a fence west from g7
Move piece and build a fence
Format: from_coordinate + - + to_coordinate + direction
Description: Move a piece from one square to another and build a fence from the destination square.
Examples:
- d4-d5n - Move from d4 to d5, then build fence north from d5
- a1-b2e - Move from a1 to b2, then build fence east from b2
- g7-f6s - Move from g7 to f6, then build fence south from f6
