A dumb, single-threaded Boggle solver
According to the super reliable source of Wikipedia, Boggle is a word game played using a plastic grid of lettered dice, in which players attempt to find words in sequences of adjacent letters.
If it isn't obvious by now, this whole thing has depth-first search (DFS) written all over it. The solver works by constructing a trie for representing its dictionary, it then performs DFS on the board while pruning away impossible, or readily explored paths from the trie.
