I don't think is rigged.

I came 4th the last couple days and the best pre-flop hand I got was pocket 10's. I finished final table 8-10 times in May.

The problem I see with novice players is they go all in when they shouldn't on 20% chance win hands. I have folded 15 hands in a row if the odds don't favor me. If I play a hand and the flop doesn't favor me I fold. Never chase with 10-20% chance to win a hand. You need to have minimal luck on one hand maybe the whole round but you also have to be able to read cards of other players. I pretty much know who bluffs or who has strong hands most of the time and people never know if I bluff or have strong hands most of the time. So improve your skills and don't fault the software.
