I hate when people lie about there score, like, rexal6, you definately did not get 146 on your first try, even your hundredth try I bet you couldnt do that, even killjack98, I doubt you got 239. So......yeah stfu.
319. Its easy all you have to do is put the ones that are mirror peices (ones that are same on both sides) then put them in the middle. Then ones that arent equal on both sides you toss off the edge.
