This is very easy using the massive bonuses given for not retrying. If you are about to lose, go to Xbox Dashboard (restarting or quitting from the game will still be marked as a failure). Then reload the game and adventure mode, your progress will be saved up to that level and you can try again. Completing each level with no retries nets you a 100k bonus, and (if this is anything like the PC game), you will get a 10 MILLION 'efficiency' bonus at the end of the game for no retries throughout (less if you did retry, but still millions)!
So considering the bonuses, you only need to get 82k a stage :P

You should attempt this after you have done at least 1/3 of the challenges so you are a bit more skilled. Try to finish as many levels as you can on your first try as you not only get 100k points but it also gives you a bonus in millions at the end depending on how many levels you finished on your first try! You should try and average at least 380k per level. Doing this on your 2nd playthrough makes it even easier as you get to choose which master you want for each stage which can be crucial for maximizing your score!
Tip from Liad-88:
If you're losing in the level (say you got 1 ball left, and loads of orange pegs), just go into xmb and quit game, and restart it. The progress is saved from that level, but you're still on your first try (or whichever it was you tried it from). DO NOT finish the level, and then quit - it HAS to be done before all the balls have been used and you come to the 'retry' screen. This is a very easy alternative method for people to get the trophy if they have trouble with it.
So if you quit to the xmb if you're about to lose a level (you MUST quit from xmb), you can retry without losing the 100,000 points. Also, if you finish each level on your 1st try using this trick if you're about to fail, you will get a 10 million bonus at the end of Adventure Mode which should guarantee 20 million+! It is a tedious process but it is much better than finishing Adventure Mode and scoring 19 million.
