775 is the number of pictures you found in less than 30 days since you started playing (without "show solution" possible).
292 is the number of pictures you found in less than 30 days and that are still showing a countdown (no "show solution" possible).
483 (775 - 292) is the number of pictures you found in less than 30 days but have been uploaded for more than 30 days and don't count anymore in the hall of fame ("show solution" possible)
For the hall of fame, On the left you're 292 (what i just explained) In the middle you're 775 (your all time findings in the 30 days time frame) On the right you're... i don't know! Depends on how many you uploaded!
Got it?
Everyday people lose points for old movies found and gain points for new movies found! That's why the hall of fame is changing all the time, and there resides the challenge!!
