why does my facebook send automatic messages to all my friends when i play lucky slots?

[Katy]

i play the game "Lucky slots" on facebook, a few people already have asked me to stop sending them the game invites or requests for that game, the problem is that im not sending them anything, i think when i send someone who plays the game a gift, it sends it to everyone, i tried an expirement- i sent a gift to someone i know who plays the game then i asked my sister (who doesnt play the game and is annoyed with all my invites) if i just sent her a request in the last 10 min, and she said "yeah" which i know i am not sending myself. how come everytime i access this game, it sends all my friends, even tho ones who dont play this game, these annoying requests? i dont want to block the game because i really enjoy playing it, but im wondering if i should for everyone else's sake. I dont wanna be that annoying friend that is always sending the "so and so needs a neighbor..." messages. Does anyone know why my facebook does this? thanks for your help

When ever you play a game on facebook it should ask you "Allow access to your personal blah blah blah" if you click allow it will be able to send spam and stuff to your friends and when ever you interact or something on the game it spam fucks your friends. Facebook did that i guess to get more people to play a game that their friends are playing. Only way I THINK to stop this is to stop playing the game. If not, tell your friends it's not your fault and to stop bitching lol
