How do I join a public room?
Below the home page are public rooms other players created that are not finished yet. Click a card to enter — no sign-in required. Pick a room by progress: finish one that is nearly done, or join one from the start. Guests can puzzle, but progress is not saved; sign in before entering to sync to My Puzzles.
How to pick a room
Each card shows the image, difficulty, current player count, and completion progress. Near-finished rooms let you help wrap up quickly; freshly started ones usually need more time. Choose based on how much time you have.
You can join without signing in
Pieces you place sync in real time to other players in the room. While the room stays public, closing the page and clicking the same card again lets you rejoin and continue.
Guest participation does not appear in My Puzzles. To continue from your list next time, sign in first, then enter the room.
Public vs private rooms
Public rooms are open to everyone — good when you want to drop in without forming a team.
To pick your own image, set piece count, or invite only specific friends, sign in, start a game from the catalog, and set the room to Private. Private rooms do not appear on the home page; only people with the link can enter.
