The Fire Temple contains puzzles that are noticeably more difficult than the puzzles seen in the previous dungeons, as well as more difficult enemies. Many puzzles involve riding a Mine Cart, including a puzzle from which the Boss Key is obtained. Other puzzles include the use of wall switches and moving Arrow Orbs so as to hit an Eye Switch, thus opening a door. Link must also constantly avoid the deadly lava commonly found in the many rooms of the multi-floored temple. Link must also avoid trap doors that are not noticeable.
