Puzzle

A puzzle is a problem or enigma that tests the ingenuity of the solver. In a basic puzzle, one is intended to put together pieces in a logical way in order to come up with the desired solution. Puzzles are a central gameplay theme in the early Resident Evil titles, forcing players to re-read seemingly-trivial diary entries and memos and searching for event items around a location. The presence of puzzles in the first Resident Evil game is heavy enough that the completion of puzzles can be dependent on completing other puzzles.
