Optional browser preferences
Game Experience Settings
Control optional audio, haptic feedback and motion. These preferences stay in this browser and can be changed at any time.
Feedback controls
The Performance Lab works without sound or vibration. Both are off by default so challenges remain quiet until you choose otherwise.
Choose any preference above.
What each setting does
Sound plays short browser-generated cues after selected successes, errors and personal-best moments. No sound files are downloaded for these cues.
Vibration uses the browser vibration API where supported, primarily on mobile devices. Unsupported devices simply ignore the setting.
Reduce motion suppresses most celebratory animation and also respects your operating system's reduced-motion preference.
Mobile play
Challenge controls are sized for touch input, and visual-memory/search grids scale to smaller screens instead of forcing horizontal scrolling.
