Yes. Every level is generated so that it can always be solved without boosters. Boosters just make it easier.
Everyone gets the same puzzle each day. A timer runs until you solve it — tap Challenge Friends to send your time and see who is fastest.
The app is free and supported by ads. Rewarded ads are always optional, and full-screen ads appear at most once every three levels.
Progress is stored on your device and included in your normal iPhone backup. Deleting the app deletes it.
