I suggest going out and trying the "Ribbit!" badge from Poppit... try getting 1000 frogs now lol >:D
lol it'll take a long time now... frogs are maybe between 1-3 prizes per round, if you're lucky ;)
Heh... I haven't played around with Poppit 2, but in the original Poppit frogs always used to be on level 4, so one would just refresh new game until you had a bunch of prizes on level 4.
On the original poppit, there were only 3 levels :)
Okay, Row 4 is what i was referring too.... Not difficulty level. :P
