The Flurry Index

The national Flurry Index is currently 48% based on 473 submissions

The Flurry Index is a measure of how often McDonald’s mixes the McFlurry using the McFlurry machine, rather than simply dumping the mix-ins on top. A higher Flurry Index means the McFlurry at a given location is mixed more often.

New submissions are closed for now. Thanks to everyone who participated!
