Common questions
When do new puzzles appear?
At midnight where you are. Everyone gets the same four puzzles for the same date.
How do streaks and freezes work?
Finish at least one of the day's puzzles (solved or not) on its day to keep your streak going. If you miss a day, a streak freeze covers it, if you have one ready. You start with one and earn another for every seven days in a row, up to two at a time. Mixsum Plus holds up to five and adds two a month. Stats › Freezes ready shows how many you have.
What does Mixsum Plus add?
Every past day in the calendar, unlimited hints and more streak freezes. Today's four puzzles are always free, and there are no ads either way.
I bought Plus, but the app doesn't show it
In the app, open Settings and tap Restore Purchases. Use the same Apple Account you bought it with.
How do I cancel my subscription?
Apple handles subscriptions. On your iPhone, open Settings, tap your name, then Subscriptions, or tap Manage Subscription in Mixsum's Settings. Cancel at least 24 hours before it renews.
Can I get a refund?
Refunds go through Apple: reportaproblem.apple.com.
Will my progress move to a new iPhone?
Your progress lives on your iPhone and comes along when you move to a new one with an iPhone backup or transfer. Deleting the app deletes your progress.
