If you are getting perfects or near perfects the first 5 levels, that might be something you should strive for. The others require longer play (like mine field or deep submarines), or require further upgrades. RUMMAKER managed to get the deep submarines it seems in the first 7 levels. I think in the video I got the mine field one on level 12 but I didn't put all my efforts into getting more mines.
