I know how to hack mystery boxes, you must search 700;300 you will see 264 results (maybe a few more or less) then you change values to 1, repeat this process 3 times because you can only change 1 page at a time (100 results) then save and continue. **WARNING** YOUR ACCOUNT WILL BE JAILED ONCE YOU OPEN ALOT OF BOXES IN QUICK SUCCESSION, Meaning you can't participate in club events anymore. I would recommend that you link your account to your email and start a new team before using this hack. I have no luck changing other values without killing the game. I hope this helps someone, I could make a YouTube video if requested. Good luck
