Here are the rules I'm gonna be playing with:

1. Any Pokémon that faints is considered dead, and must be released or put in the Pokémon Storage System permanently.
2. The player may only catch the first Pokémon encountered in each area, and none else.
3. Nicknames are obligatory.
4. Battle is set.
5. A maximum of 10 Pokemon can die. On the eleventh death, the Nuzlocke is over.
6. No dupes clause. If on my first encounter I find a Pokemon I already have or have had, I cannot catch it and must catch the second one, for the sake of variety.
7. Shiny clause. I can catch any shiny I find even if they're not the first encounter.
8. Any use of the Day Care is forbidden.
9. My Pokemon can't be of higher level than the next Gym Leader's/Champion's highest leveled Pokémon.
10. Each Gym Badge acts as a checkpoint. If the player gets a game over, they can start from when they got their previous Gym Badge.
