Multiple solutions
From IFWiki
A puzzle with multiple solutions is one that allows more than one approach. For example, to reach a high object, it might implement all of the following commands:
>JUMP.
>STAND ON CHAIR THEN GET BANANA
>THROW ROCK AT BANANA. TAKE BANANA
Multiple solutions tend to require more effort on the part of the author of a game, but can be very satisfying to players.
