We now offer a premium subscription feature that includes the option to play daily challenges 7 days in advance, along with Premium Themes and no advertising.
If you select a future date on the Daily Challenge calendar, (yellow highlighted days) and receive a prompt to subscribe then you may not have an active subscription.
Subscribing is optional, however, non-subscribers will not have access to the premium customization options, Future Daily Challenges, and ad-free experience.
You can continue to play the Daily Challenges, but only for the current calendar day (or previous days).
