|Break through all four walls|
|Run into a boarded-up door|
|Some doors have traps behind them|
There is a row of four walls, one behind the other, each with four doors. Some of the doors are paper, but the others are boarded up.
The contestant has to run full-speed at a door. If it's made of paper they will burst through it and move on to the next wall. If they choose a wrong door, which is solid, they will bounce straight off and lose the game.
Not all of the wrong doors are solid. Some are made from paper but have a net fixed behind. If a contestant runs through one of these they'll be caught in the net and also lose the game.
If the contestants make it through the second wall they'll be confronted with the Boxing Monster. They will have to make their way past him to continue on. If the contestants choose wrong this time they'll end up getting a pummelling from the supersized-samurai.

Skip and Knock
Knock Knock started as an extention to Skipping Stones. A wall was placed on the bank after the pond, which contestants had to try and break through to clear the game.
In episode 5 a second wall was added behind the first.

Knock Knock became a game in its own right from episode 6 onwards, with four walls to be passed though.
