Please make sure your operating system and game version are up-to-date.
If you are using Wordmania App or The PCH+ app, please check to see if an update is available.
If your game still crashes upon launch or after playing for some time, here are a few possible solutions:
First, try a simple soft restart: Hold down the lock button located at the top of your device for a few seconds, then slide to power your device off when prompted.
If this does not help, try a hard restart: Hold down the lock button and the home button for a few seconds until you see the Apple logo. Ignore the prompt to power off and just keep holding those two buttons. This method involves a substantially longer restart than the soft restart mentioned earlier.
If neither the soft nor hard restarts work, try deleting the game from your device and re-downloading it. Note that all game files will be removed and will be unrecoverable.
