I previously wrote (on this same thread, in fact) about Level 466.

Here is what I wrote (slightly edited):
Nuts are very valuable, so try to save them for the endgame and advance in the lower levels without using them.
At the start, guess which of the four colors will come up most frequently and throw that at the ice bubbles. Use any other colors to collect the two lowest prizes: each two nuts. Once ice bubbles are colored and cleared, all the blocking balls on each side drop. Attack the ice bubbles on each side by trying to color and drop them. Continue firing color bubbles to drop doom bubbles on both sides. Now use a bank shot to hit a pair of fireworks bubbles. Ideally, this will start a chain reaction to drop out everything on this stage. Moving up, if directly above is a color bubble, throw matching bubbles to clear it out. Throw other colors to collect the side prizes, each one nut. Should have six nuts now. Begin using nuts to attack structure at key points, with the goal of reaching all the way to the top inner fireworks bubbles. If you can make it all the way there, one hit to a fireworks bubble should be enough to set off a chain reaction for the win.
