Nibbles

Nibbles is a text mode implementation of the snake genre developed by Microsoft. Its visual presentation is composed entirely of ASCII characters, which form both the playable snake and the environmental walls.

Gameplay involves directing a snake to consume numbers that appear randomly. Each successful consumption causes the snake's length to increase, which directly raises the risk as the player must now avoid a longer tail. Collision with any wall or the snake's own growing body results in failure.

The challenge escalates across levels through the introduction of more walls, making navigation progressively challenging. Alongside a standard single player experience, the title also supports a two player competitive mode.
