Common questions
Is my progress saved?
Yes, on your device. There are no accounts, so progress stays on the phone or browser where you play. Deleting the app, or clearing your browser's site data, resets it.
Can I move my progress to a new phone?
Not yet. Because there are no accounts, progress can't follow you between devices.
I can't hear any sound.
Check that sound is on in the game's Settings, that your volume is up, and on iPhone that the ring/silent switch isn't set to silent. The games are designed to play quietly alongside your own music or audiobook.
Why don't I feel vibration in the browser on iPhone?
Safari on iPhone doesn't let websites use vibration. The iPhone apps support it.
Do the games cost anything or show ads?
No ads, ever. The games are currently free to play.
What's this "share play data" setting?
It sends anonymous information about how levels went (for example, how long a level took), which helps us tune the difficulty. It contains nothing about who you are, and you can switch it off at any time. See the privacy policy for details.
