About Pass the Spark
Pass the Spark is a free browser-based two phone game where you flick a glowing spark back and forth with a friend. Open it on two devices sitting nearby, then tap and drag to flick the spark from your screen into your friend's phone. The spark carries momentum as it travels across the room, creating a satisfying real-time interaction that rewards quick reflexes and timing.
This cross device toy uses simple physics to simulate momentum relay — the harder you flick, the faster the spark travels to your friend's phone. No app installation is needed; just open it in your phone's browser and share a connection code with your friend. Start playing instantly with no signup or account required, making it perfect for spontaneous, immediate fun between two nearby phones.
Pass the Spark is completely free and runs entirely in your browser — no signups, no logins, no accounts needed.

It's designed as a pure, lightweight toy for quick bursts of interactive entertainment, free from complexity, ads, costs, or unnecessary barriers to play.
