Common questions
How do I play?
Tap a block to turn it. Lead each colour from its source to the shape of the same colour. A mixer pours only when both of its inputs are fed. Tap ? in any level for an animated guide.
Where is my progress saved?
On your device only. There is no account and no cloud copy, so deleting the app also deletes your progress.
How many hints do I get?
10 free hints and 3 sets of new pieces every day, reset at local midnight. When they run out, you can watch a short ad for more. A hint always moves you towards the solution; if no useful move exists in Endless, it says so and costs nothing.
When does the daily challenge change?
At midnight UTC, at the same moment for every player, so everyone plays the same board on the same leaderboard.
Why do I see ads, and can I change ad tracking?
Ads keep the game free. They never interrupt a level. You can change your ad privacy choices in Settings → Privacy (where your region requires it) and in your device settings. See the privacy policy.
My score is not on the leaderboard
Make sure you are signed in to Game Center (iOS) or Google Play Games (Android) and online when a run ends. Only your best score counts.
