What I meant was: many games incorporate a "hint" system within the game, where you can type "hint", and it will offer some help based on where you are (your current context) and/or on the current puzzle. Sometimes, if the game is well-written enough, each time you type hint, it will give you a deeper level of hint. The initial hints may be general or vague, but finally it will just tell you flat out what to do. But if you go to a different place in the game or are at a later point, you'll get different hints. That's what I meant by "context-specific".
