Light mode
Shift the tone from dark to light.
Larger text
Increase the text size across the whole site for easier reading.
High contrast
Push the text and lines to full strength for maximum legibility.
Reduce animations
Calm the motion: the aurora, the wordmark sheen and the cursor glow stop moving, but the look is unchanged.
Performance mode
Strip the heavy visual effects (background blur, ambient glow and grain) for the smoothest rendering on older phones and laptops. Best if you mainly want the games in Play and Labs to run fast.
Mute sounds
Silence the arcade sound effects in Play and Labs. Stays in sync with the mute button inside each game.
Install as an app
