Nibbles is a worm game. The player controls a 2D worm while trying to get food. Getting food gives points, but hitting anything causes a loss of points. When all points are lost, the player loses.
The game's objective is to navigate a virtual snake through a walled space while consuming numbers (from 1 through 9) along the way. The player must avoid colliding with walls, other snakes or their own snake. Since the length of the snake increases with each number consumed, the game increases in difficulty over time. After the last number has been eaten, the player progresses to the next level, with more complex obstacles and increased speed.
