Kwijibo is free! The subscription includes some fun enhancements, but is completely optional.
Kwijibo is simply the most fun word game ever invented! Try it out now against the Kwijibots, and see for yourself. Or for twice the fun, host the game online, and play against other real people across the country!
The bot dictionary now contains over 8,030 words.
Kwijibo uses Skysaw's Dictionary Library. If you're writing a word game, you need this!
