I find the event very nice but i agree with you maloukess its a dangerous one, if anyone is interested here goes some advices

First of all you have to know this event is all about luck so you can win or loose, don't spend tokens you need

In my opinion its not made for people with fewer tokens then about 300 but the first thing a manager should think is how many tokens am i willing to invest

The you must constantly acess what you have won and how many tokens you have lost and determin a limit to your losses

Last season during the hole event i lost abou 700 tokens, but the thing i got were more than worth it, i got abou 400 green packs, and many hability boosters which i think are the best prizes in the event
