I thought it was first too lol. I reloaded the page after the discord announcement that kilominx was closed and it said I was in first but no such luck. With an 18.01 average, Nikhil 100% deserved to win.
So apparently I did end up getting first. I DMed Nikhil on Discord and he said he misscrambled because he did the flips wrong (he did x instead of x2).
I'm almost positive he uses the shengshou. One of them(MFJS I think) has centers(making it not a kilominx) and the other one is trash. There's a new one coming out soon though, I'd wait for tha
I use the shengshou, but 100% wait until the qiyi comes out before you buy one. The shengshou is currently the best on the market, but it's still trash.
