## Introduction

Nibbles is a game where the user controls a worm. The worm moves around the board, eating diamonds while avoiding the walls placed around it.

To run Nibbles, select Games Nibbles from the Applications menu, or type `gnibbles` on the command line.

Nibbles is included in the `gnome-games` package, which is part of the GNOME desktop environment. This document describes version &VERSION; of Nibbles.

## Nibbles Objective

The objective of Nibbles is quite simple. You control the worm and if the worm runs into a wall or runs into itself, you die. You get ten lives before your game is over. You win by either beating your own high score (or a friend's) or by completing all the levels. It is also possible to play against worms with artificial intelligence.

&appname; also features multiplayer support with up to six competing human players in hotseat mode.

### Diamonds

Nibbles has numerous different diamonds to eat. They are each a different color and serve a different function. Only the pale purple diamond is guaranteed to be around long enough for you to eat it (in fact, you have to eat them to finish the level). The other diamonds are all bonuses, but they only stick around for a short time. We'll leave it up to you to discover just what the bonus each colour gives, but they all affect either the score, the length of the worm, or both. Be careful when going for these bonus diamonds, don't cut yourself off from the ordinary diamonds that you need to finish the level.

Keyboard controls

- This list let you change the keyboard controls for the given worm. To change a control, double click on the appropriate entry and then press the key you want to use for that control.

Use relative motion

- Rather than left sending your worm toward the left of the screen, right toward the right and so on, the left and right keys make the worm perform a left or right turn. For example, if the worm is moving to the left and you press the left control it turns to head toward the bottom of the screen.

Worm color

- Customize the color of your worm so you can tell it from your opponent's worm in multi-player mode.
