## Overview

The object of the game is to form groups of islands linked by bridges.

### Definitions

Island: 4 orthogonally adjacent tiles of the same colour.

Sandbank: Fewer than 4 orthogonally adjacent tiles of the same colour.

Bridge: Game piece that connects 2 tiles of the same colour.

Water: Empty space on the board.

## Game Start

1. The first player places 2 light tiles anywhere on the board.
2. The second player chooses to play as the light tile or the dark tile player.
3. Play resumes with the dark tile player.

## Game Turn

Each player takes turns to place either:

• 2 tiles of their own colour, or
• 1 bridge.

### Place 2 Tiles

Tiles can be placed anywhere on the board except:

• Under bridges, or
• Where a tile becomes adjacent to an island of the same colour, even diagonally.

### Place 1 Bridge

A bridge can be placed between 2 tiles of the player's colour that are 2 spaces from each other in any direction orthogonally or diagonally, or at a knight's move.

• The centre of a bridge must be over an empty (water) space (knight's bridge needs both water spaces), not a tile
• Each tile can have a maximum of one bridge connection.
• Bridges may not cross each other.

## Game End

Game end is triggered when either player:

1. Is unable to place 2 tiles, and
2. Chooses not to (or is unable to) place a bridge.

The dark tile player can always take an equal number of turns.

Note: unlike the printed rules, in the BGA implementation there is an infinite supply of tiles and bridges. Thus, the game will only end when a player has fewer than 2 valid squares available for tiles.

### Scoring

The players score each group of islands connected by bridges (including connections via sandbanks) according to a rule of triangular numbers:

 # connected islands Score 1 2 3 4 5 6 7 8 9 10 11 12 1 3 6 10 15 21 28 36 45 55 66 78

### Tiebreaks

1. Most islands.
2. Most bridges.
