Big Boggle is a timed word game where players attempt to find as many connected words as possible from the face up letters resting in a 25 cube grid. When the timer runs out, players compare their list of words and remove any shared words. Points are then awarded for remaining words, depending on how many letters are in the word.

Big Boggle is similar to the standard Boggle, but with the following changes:

• uses a 5x5 grid instead of 4x4
• the minimum word size is 4 letters instead of 3
