## Overview

Four wins is a game for two players.

Each player is represented by a color (yellow and red). The goal of the game is to get four connected pieces of your color into a row, column or any diagonal. This is done by placing one of your pieces into any of the seven columns.

A piece will begin to fill a column from the bottom, &ie; it will fall down until it reaches the ground level or another stone. After a move is done it is the turn of the other player.

This is repeated until the game is over, which is when one of the players has four pieces in a row, column or diagonal or no more moves are possible because the board is filled.

## Rules

The board is separated into three regions.

The game board is constructed out of 7x6 fields which will be filled from bottom to top. The fields are marked in the color of the player who made the current move. On top of each column a colored arrow shows were the last piece had been put.

The status display shows which player color starts and which color is played by whom (player, computer, remote connection). It further shows the level of the computer opponent, the number of moves done as well as the computer calculated chance of winning. This chance is calculated only if the computer opponent makes a move. A positive number means that the player has an advantage, a negative number means that the computer thinks he is better.

The table display shows the number of won, lost and drawn games is noted for both player. Also the number of aborted games (Brk) and the sum of games is shown.

## Remote connections

It is possible to play the game over a network connection with another computer. One of the computers will act as game server. This one can determine who should play which color. You can configure the network options in the game menu, network dialog. There you also find a chat dialog box which allows you to speak with your friend.

When a network connection is build you are asked to enter a remote host and a port. The port can usually just be left untouched, but if you know what you are doing replace it by another number, which has to be the same in both player games of course. The hostname should be the name of the remote host to which you are connecting. Only the client in the connection has to supply a hostname. It is often wise that the player behind a firewall chooses to be client as the firewall might not allow incoming connections.
