Sometimes i see players who get 2-sock items from lotery ( cap/ hat / coat / ring / neck / boots / shield .etc)

But I was spend ~430 cps in a day with 2 accs and i get only stupid things ... (like : exp balls / +1 stone pack / +2 stone / unic packs / ref packs / +3 stone <= the valorous thing what i get trying ... / ...)
My broather tryed to found +stones and he get a +8 arch cap .... thats amazing .....
some players told me that : - Try to oppen the same box for some times ... and i tryed but i get only the mentioned things up.... i was see some posts in this forum and a member taked a post with the teory what i want to put under the "?" ....
