Guests keep progress in this browser. Your account opens the full catalogue and synchronises new rounds across devices. Challenge, Practice, Daily sprint and supported Endless modes keep separate records.
A heart saves a favourite.
Press a game card’s heart to add it to your playroom. Press it again to remove it. The Saved filter in the catalogue shows only the games you have chosen in this browser.
Favourites do not follow you to another device. Private browsing or a browser that blocks site storage may prevent them from being kept. A storage message tells you when a save fails.
A finished attempt makes a record.
When a playable game reaches its completed or ended state, it records the number of finished attempts, successful challenges and your best score for that game. An unfinished round is saved periodically and when you pause or leave. Use Continue saved round to resume it. Signed-in saves follow your account; guest saves stay in this browser.
Scores have different meanings in different mechanics. Compare your own attempts at the same game; the catalogue does not turn them into a shared competition.
A preview is just a look.
Automatic previews make legal moves in the same game engine as the playable version. They do not add scores, finished attempts or completions to your personal record. You can close a preview and choose Let’s play for your own attempt.
You can clear your playroom.
The Clear this device option in My playroom removes this site’s favourites and completed-game scores from this browser. It does not clear other websites. Your browser’s clear-site-data tools can also remove them.
Clearing this device does not delete account progress. Earlier browser records are kept separately and are not silently merged into your account.
