Anyways, I find that the best way to get blue bricks, or any bricks, for that matter, is to use the magazine modules! I click on the Lego Magazine Module, Rank 2, which grows blue bricks, will get you another brick! In other words, one click is equal to one brick!
Congratulations on ranking up, and I am glad to see that you "slowly but surely" strategy is working!
