Puzzles are often intuitive in some way, the clues already set before you. You either have to find some written or visual hint within the game, deduce the solution using logic and experimentation or bypass it with an item or spells. Failing that, brute forcing a puzzle can help you overcome it, even if you only learn how to solve it after you've done with this method.

If failing triggers a one-time trap, surviving that peril can allow you to progress if the puzzle wasn't to open a door. There are other ways that failing a puzzle can allow you to progress and in this video, we'll discover one of them.
