This isn't ALL of the levels, nor all the prizes... But, it's a semi quick guide to seeing what prize you'll get.
DISCLAIMER: Due to the way this game works, the score given is NOT guaranteed to be exact/the same when you play. These are MY scores after a 'normal' gameplay. (Normal meaning I wasn't trying to set up super combos, or finish as fast as possible).
Again, this is a quick reference for estimated scores/prizes you can obtain from a certain level.
