so this is called nuzlocke i found it online will i was watching a play through on pokemon Y and came a cross it, i tried it out and it's hard at first but after a few goes of restarting my game i finely got through it so now i'll tell you the rules of the nuzlock.

1. nuzlocke starts after you get pokeballs

2. you can only catch one pokemon in each place (say like if you catch a pokemon in route 1 than you have to wait till route 2 to catch one more pokemon and so on)

3. if one of your pokemon feint than you have to realise it (it's dead thats why it gets realised)

4. rule 2 dose not count for any legendary or shiny pokemon.

5. you must nickname ALL pokemon

6. you can't catch the same pokemon twice

7. if you encounter a pokemon you have or is dead then you must find a different encounter

so those are the nuzlocke rules and you can see why i had troubles doing it but it was fun and hope that if you try it that you'll have fun to :3

Update: something I forgot Is that the Pokémon u catch MUST be the first encounter unless it's a Pokémon u already have
