This is a cheat sheet tool, not a game. Enter the letters from your real Boggle board and it will find every word you missed. Hit "Random Board" to try a sample grid, or type in your own letters.
Scoring
This isn't a game — it's a lookup tool for after you've already played a round of Boggle. Type in the 16 letters from your board (or hit Random Board to generate one), click Find Words, and the solver traces every valid path through adjacent cells to find words you missed.
Most people spot about half the words on a board during play. The solver reveals the rest, grouped by length and scored by standard Boggle rules. Each word links to its dictionary entry, so you can learn the ones you didn't know.
