Does anybody know the Rat Pack Challenge?

I've got a huge problem with my mobile photos... since I've bought my new smartphones five months ago, I've shot about 5.500 pictures with it.

Well they're saved on the SD card, but this can't be a solution and so I've already tried some apps for sorting out my mobile photos, but they are too boring and I've resigned soon.

Now I've found on Google the Rat Pack Challenge which should in principle the same, but which also is a game.

But before installing this, I prefer to ask if anybody already has tried it out and can tell me more about it.

Thank you in advance for your answers!

Thank you very much for your answer!

Meanwhile I've tried to install the Rat Pack Challenge and I must say that it has been a good idea. In the first two weeks I've sorted out about 200 mobile photos and for me it's a quite good result.

But I still can't understand the meaning of the golden nuggets and of the diamonds. Well... I have a lot of golden nuggets and I haven't understood what I can do with them. Or are both things symbolic?

Thank you very much for your explanation!

Haha you're not the only one which is a bit generous with taking out the camera of the smartphone... we've got the same problem, but I don't have your same discipline in sorting out the photos.

Oh that's great that I also share my pictures. But but... how can I get the diamonds?

Thank you very much for your explanation!

Do I understand it right that the diamonds and the golden nuggets probably have the same functions?

And do I have to delete ten pictures from the cloud for getting a diamond?
