We listened to your feedback regarding issues with the Outspell dictionary. In July 2020, we upgraded the game's dictionary from a 2012 version to a more recent dictionary, created in 2019.
The new dictionary contains 100,000 more words than the previous one, bringing the grand total of words to 280,000.
You might even find an "Easter Egg" hidden in there! Try putting the word "Arkadium" on the game board and see if it works. Enjoy!
