Boggle is a word game trademarked by Hasbro. The game is played using a grid of lettered dice, in which players attempt to find words in sequences of adjacent letters. Klingon Boggle is described as being essentially the same as normal Boggle, but with pIqaD letters replacing the standard Roman alphabet. Klingon is a full language developed by James Doohan for Star Trek: The Motion Picture, and expanded for Star Trek III: The Search for Spock by Marc Okrand, who enlarged the lexicon and created a grammar around the original dozen words Doohan had created.
To play Klingon Boggle, the use of The Klingon Dictionary is permitted.
