"What the heck" are you thinking? Well, it is true. How to do that?
Try this: Get a trick bonus on air where is lots of air
Do 8-13 times front flip
Then, do a 4560 flip and there it is.
If you do this correctly, you should get about 10000 points (at least), I got 88065 points on my second time.
My best score at snow jam (peak 1) is 986145 points, but my friend got 1000000 points (he told me, im not sure in his records in snow jam is 1000000 points, so believe or not, I can tell you ONE THING: This is the ultimate trick).
