Gomibako which is trash can in Japanese tests your Tetris skills as well as your recycling skills on the PlayStation 3.
You have to load up a trash can with thrown-away crap, one at a time. You're attempting to stack them up such that you don't leave any empty space, and can thus fit a lot more inside. But you can also smash items down into the can, breaking them or breaking the things they land on.
Every once in a while, you get a sword that is on fire, and this is how you clear out items from the can. Sticking the fire into a wooden or paper object will set it ablaze, and if you can line up a chain reaction, you can clear out a lot of the crap in your trash can and start again. Eventually, you have to start fitting in really huge items, and this is how you can lose the game -- if your can gets too full and three items fall out, you're done with the level.
