When you select one of our daily puzzles, it connects to our server to retrieve the tile layout for that puzzle, so that everyone who plays gets the same starting layout for fairness.
If there's a problem getting these puzzles, it will give an error popup that the puzzle isn't available.
Connection Problems
The main reason the game would be unable to connect is that you don't currently have an active data connection. This normally means you've gone outside the range of your WiFi, or perhaps you're in a poor reception area for data.
Check to see if you can reach a web page on your device - if you can, then the problem is further along the chain!
If the game can't connect to our server, then it will put up a short message at the top of the 'help' page from the title screen.
It can sometimes be worth rebooting your WiFi router you can't reach the internet.
Usually any problem with retrieving the games will be solved by trying again a little later, but if you get a connection problem persistently, please get in touch!
