yes, u have to first buy the key, (sorry it costs a few coins) then u have to find the fruits on every map, which gives you bonus points, depending on their difficulty, the easiest fruits are at the top of the map list- so castles- and the hardest at the bottom
nope what i tend to do to get coins easier is just switch to vpn to countries with less people like sri lanka india like that less people play so i can just easily kill them
