Pendulum Swing

Goal of the game

In Pendulum Swing you play with the pitch of your voice (hum low or high). A cheeky monkey swings on a jungle vine. HUM or sing a LOW note to pull the vine SHORT and a HIGH note to let it out LONG. The monkey swings on its own — change the vine length so it flies through the golden RINGS to score and grab bananas for bonus points.

Angry bees buzz around the swing: touch one and you lose a life. Go quiet and the vine keeps its length. Power-ups: Shield, Slow-Mo and Double Points. Tune the 🎚️ sensitivity slider for your voice.

Device requirements and privacy

Pendulum Swing needs a microphone — the one built into your phone, laptop or headset is enough. Allow microphone access when asked; the sound is analysed live in your browser and never uploaded. It is free to play; free players may see a short ad between rounds (never during play), and Premium removes all ads.
