Smash Ace
1. Turn on your 3DS.
2. Make sure it is on at all times.
3. Charge it overnight when it is low on batteries, make sure to place it over a fabric that heats up easily such as wool or cotton.
4. Watch the plastic weaken due to the heat and energy.
5. Make sure you play with it enough so that the hinges break and become useless.
This happened to me mainly because of the Smash 3DS demo, although it was a very minor crack. It came back to haunt me today when the right hinge suddenly chipped off, and now the 3DS is basically hanging off one hinge and some duct tape which is failing to do the job. At least I can still play the game, unlike those who lost their Circle Pads.
