It's not cheating, per se, but somehow, you beat a boss or solved a puzzle in a way the game didn't really anticipate.
For example, in Majora's mask, when fighting Goht, instead of following him around the arena as a Goron, you can just stand in the doorway and peg him with Fire Arrows until he dies.
Or in FFVI, when fighting the Atma Weapon, if you work hard to get the proper items, your whole party can both float and have reflect on for the whole battle, meaning he can only attack physically, making the fight way easier?
When have you exploited a game's possibilities? Remember, this isn't about breaking a game or using cheats, it's all about exploiting what's already there.
