A few simple moves to get started.
Getting started
Tap the button in the center of the screen to ignite or turn off your blade. Swipe left or right along the bottom to change your hilt. Move your iPhone gently to feel the sound and haptics respond.
Connecting with a friend
Open the app on two nearby iPhones and allow local network access. The app automatically searches for an available opponent. The top lamp is red while searching and green when connected. You can also play solo before connecting.
Trouble connecting?
Keep the app open on both iPhones and make sure Wi-Fi and Bluetooth are enabled. Check Settings → Privacy & Security → Local Network for Saber Duel. On supported devices, also check Nearby Interaction permission. Bring the devices closer and try reopening the app.
Missing sound or haptics?
Check your media volume and connected Bluetooth audio devices. Check your device’s haptic settings too. Available feedback may vary by device and settings.
Requirements and safe play
For iPhone with iOS 26.4 or later. Use gentle movements with plenty of space around you. Never physically strike phones together or swing your phone toward people or objects.
