1) In Duck Hunt, each round is comprised of 10 ducks (either 1 or 2 at a time) or clay pigeons.

In the first 10 rounds, you only need to hit 6 to go on. But, the vital hits increase starting at round 11 & you have to be perfect from round 20 onward to pass.

2) In Super Mario Bros. 3, you’ll need 2 out of the 3 Warp Whistles to warp from World 1, to World 9 (Warp Zone), to World 9 again, to World 8.

You need to be in World 7 or higher in order to reach to warp pipe to World 8. In view of the fact that the Warp Zone is classified as World 9, using the 2nd Warp Whistle there will take you to the the World 8 pipe.

Just a friendly reminder, the Warp Whistles are located…

A) Behind the exit of Stage 1-3

B) In a hidden room in the World 1 fortress

C) Held by the traveling fire Bros. in a secret part of World 2

I won’t tell exactly how to get them… but they’re pretty much common knowledge with most players.

Hope that helps!

You can reach World 8 from World 1 by using only the first two of them (found in level 1-3 and the World 1 Fortress… warp from 1 to the warp zone, then use the following whistle while you’re in the warp zone to reach world 8), but you can’t warp to the last level… you have to start at the beginning of World 8.

you have to get to like world 5 and then you can warp.

the reason that is, each level is in a row. and only particular ones go higher than it.
