How to Play

Wurmus was a snake-like game of tag once popular on playgrounds across the globe. Players link arms with the head of the worm as they chase and add players to their tail. But beware! They are also vying to decapitate the worm, and if a link is broken, all the detached players are free. The game ends when the head loses its tail.

In this faithful recreation, you control the head of the worm in an endless playground where new opponents regularly enter at increasing skill levels. Capture them and avoid decapitation to increase your score.

How long will your worm survive?


Occasionally opponents will carry special power-ups. These are indicated by particle effects and a unique sound. Capture them to apply powerful status effects with a point bonus.


Stability protects players from capture. Collecting this power-up grants five seconds of stability to all allies.

One second of stability is also granted to newly captured allies and newly freed opponents. If the next ally in the worm has stability, then their remaining duration is added as a bonus. This bonus stacks.


Fear sends opponents running away from the head. Collecting this power-up inflicts five seconds of fear upon all opponents.

Fear is also inflicted upon newly freed opponents. Its duration varies based on their difficulty level.


Taunt beckons opponents toward the head, ignorning all other players. Collecting this power-up taunts all opponents for five seconds.


Wurmus supports a variety of input devices. Its controls are comparable to standard first-person games with strafing and turning. Although remapping of controls is currently not available, alternate control schemes have been provided where appropriate.

Audio Description

Wurmus can be played entirely without graphics.

The game opens with calming music that plays on all of its interstitial screens. Once in-game there are a variety of synthesized sounds that give Wurmus a retro feel. A notification plays whenever a new opponent enters the game. Faint footsteps grow louder as they approach. Facing them emits sustained horns that form musical chords. Capturing them plays a delightful melody. Cues for each power-up, and a game over bass drop, pepper the experience.

A graphics toggle has been provided in a toolbar on most screens to experience Wurmus as an audio game.

Graphical Description

Wurmus can be played entirely without audio.

On the screen are minimalist vector graphics, with bright pastel colors against a black background. The game is presented top-down, with the screen rotating so the top is always the forward direction. Each player is represented by a circle colored based on their team. When they collide, particles explode like confetti in various directions.
