A little help.
For support or a puzzle correction, email [email protected]. Include the page link, your device and browser, and what happened.
The game is still loading
Check your connection and refresh once. The public calendar, walkthroughs and guides can be read without loading the interactive game. If an extension blocks the game, try another modern browser. Do not clear browser data as a first troubleshooting step: doing so can erase local saves.
Where is my saved puzzle?
Return to the Lobby and choose Continue in the same browser and device. Local saves are not shared with other browsers or the mobile app. Private browsing, clearing site data or uninstalling can remove them. There is no account login or cloud restore.
Why did my correct equation not add a green row?
It may repeat a solution with the terms of an addition or multiplication swapped. Read the unique-solution guide. Check brackets, allowed choices and exact division too. When reporting an issue, send the complete equation and puzzle URL, not just its target.
How do I share a puzzle?
Use Friends in the game to open your device’s share menu, or copy a public daily-puzzle or walkthrough URL from the browser. The recipient can read the puzzle page and choose Play. Availability of WhatsApp, Messages and other share targets depends on the device and installed apps. You choose recipients and confirm sending yourself.
Calendar and time zones
The shared daily puzzle changes at midnight UTC. That may be a different local time on your device. The public calendar shows only published dates, and the difficulty filter can make other published dates appear muted. Select All levels to show everything.
Hints, ads and analytics
Hints and reveals are free on the website. You never need to click an advertisement to earn a reward. Website analytics is optional; use Privacy choices below to allow or turn it off. Advertising privacy choices are separate. Mobile rewarded ads and notification settings remain within the app.
Reset or request deletion
In the game, open Settings and choose Delete Performance Data Saved on Your Device to reset local game performance. For data from earlier account-based releases, follow the deletion help. Read the privacy policy for service and analytics details.
Never send passwords, authentication codes, private keys or contact lists to support.
