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. Your gameplay data stays on your device and your friend's device; nothing is stored on remote servers or tracked. It's designed as a pure, lightweight toy for quick bursts of interactive entertainment, free from complexity, ads, costs, or unnecessary barriers to play.

Frequently asked questions

How does Pass the Spark work?
Open the game on two phones that are within the same room, then share a connection code. Tap and drag on your screen to flick the spark toward your friend's phone. The spark travels across with momentum based on how hard you flicked it, and your friend can flick it back. The game uses real-time connection to sync the spark's position between devices.
Do I need to download an app or sign up?
No. Pass the Spark is entirely browser-based — just visit the website on your phone and you're ready to play. There's no signup, login, or app installation. Two players simply need to be on the same connection, and you can start a new game instantly.
Can I play Pass the Spark with someone far away?
The game is designed for two phones in the same room or nearby. While the browser connection is online, the core experience centers on the satisfying tactile feedback of flicking and watching the spark move between nearby devices in real time. Playing across longer distances works technically but loses the intimate, spontaneous feel of the toy.
Is Pass the Spark free and private?
Yes, it's completely free with no ads or hidden costs. Your gameplay stays on your device and your friend's phone — no data is sent to a server or tracked. It's a minimal tool that respects your privacy while giving you a lightweight way to pass the time together.
Is Pass the Spark free to use?
Pass the Spark is 100% free — no signup, no watermarks and no usage limits. It’s one of 200+ free tools we build and give away.
Where do my files or messages go?
Straight from one device to the other over a peer-to-peer connection — nothing is uploaded to or stored on any server.
