## Introduction

&ksnakeduel; is a simple snake duel game. You can play against the computer or a friend. The aim of the game is to live longer than your opponent. To do that, avoid running into a wall, your own tail and that of your opponent.

&ksnakeduel; is a simple Snake-like game. The aim is to survive as long as possible and eat as many fruits as you can.

You can switch between these games using the game type selector in the configuration dialog.

## Playing &ksnakeduel;

### Rules

Once a round is started, the players do not stop moving forward (unless the game is paused). All you have to do is avoid crashing by changing your players direction. Additionally you can try to hinder your opponent. For this it is possible to increase the velocity by pressing your accelerator key.

A round starts when all human players press a direction key. The initial moving direction is then in this direction.

If you want to interrupt playing, select the P Game Pause menu item. Additionally the game is paused when the game loses the keyboard focus, ⪚ when switching to an other window.

To continue the game, select again this menu item or hit the keyboard shortcut. The game will also continue if you press one of the direction keys. But be careful, your player switches to this direction immediately.

A game consists of several rounds, and ends if a player has at least nine points, and additionally two more points than the opponent. The current score is always displayed in the status bar.

You can change the difficulty level of the game using the Settings Difficulty submenu or the drop-down box on the status bar. The difficulty influences the speed of the game and the computer player.

### The Computer Player

You can play against a computer. The difficulty level of the game influences the intelligence of the computer player.

At low levels the computer doesn't care about the opponent and just moves around. At higher skill levels the computer tries to hinder the opponent when he comes near.

### Using the Keyboard

Each player has five keys. Four keys for changing the direction and one to accelerate.

The direction keys do not have to be held down. Simply press them once to change the direction of your player.

Acceleration only occurs while the acceleration key remains depressed. When you release the acceleration key, velocity returns to normal.

You can alter the keys using the Settings Configure Shortcuts… menu item.
