I'm not shore how advanced this is but it is based on the popular game show "Deal or no Deal"
It has:
38 sprites
132 scripts
36 varaibles
1 list
Uses a temp variable to shuffle up the variables
It is able to make a list hide and show
uses maths and lost and lost of if's

Yeah That's Pretty Advanced

All right, let me say this here."Advanced" projects arn't determined by the number of scripts, but rather the efficency and complexity of the script.For instance, newer members tend to make a bunch of short, simple scripts to do a job that a scratching veteran could do in about 1/10th of the scripts and sprites used.For instance, I made a tank scrolling game with 80-something scripts and 15+ sprites, and I now realize I could do the same thing with about 6 sprites and 15-20 scripts, dramatically reducing lag. Another prime example would be 1-sprite 1-script games,(LINE is the best example of this now, or maybe SQUARED)which represent the pinnacle of efficency in scratch.

I made 3-4 of those. Doody however, I dont he/she has EVER made one.

OMG! ANOTHER DOODY! http://scratch.mit.edu/users/Doody1000

I really think that the more scripts there are, the less confusion there should be for the computer. Its like telling an artist EXACTLY what you want. IDK why there is lag with a bunch of scripts.

I have a feeling that this is becoming sort of a Inspiration and More topic.
