1405 XP to Level 11!! ... Sigh. Getting only 90 XP a week, this is going to take a while! Although I got a Diamond the other day, I won't be getting one again. I spent 2 hours getting it. All was OK, I got it. So, a couple of days later I tried again at another challenge, got Diamond after 2 hours only to see that I'd lost it three hours later and at that time I just couldn't get it again. It seems that Diamond is only given to the 20 best people in the world, can anyone confirm that? I got a 23rd place in that challenge and only got Gold (I was at an 8th place first). This is both awesome and sucks at the same time as the number of total players increases over time. Luckily, getting Gold is only a matter of playing for about 5-10 minutes on each daily challenge.
However, doing challenges over and over again easily nets you 10k Lums so I'm currently at 850K lums so only about a week away from 1 million Lums!
