I think the US PGL's "play to befriend a pokemon" is partly random, it works like a gumball machine: it's randomly decided which pokemon you get after you play the game, but the more of one color you get in there, the more likely you'll get it. Also, to get an "eeveelution", you haveto beat ALL 4 LVLs! It's SO HARD! I only beat it once, and by hard, I mean lvl 4 is hard. By the time I get to lvl 4, I only have 1-2 balls left.
