I got a BF 6 weeks ago and it took a little while but I have 3 scores around 2.9 billion. The 20x bonus is key for big scores . You get it in the Edward awards. I have gotten as much as 900m in bonus. Obviouly you need to hit a lot of ramps and multi-ball after getting 20x. Also jack pots hitting 2 lit ramps are important to light super jackpot. Most modes can get you 50-90-million. You got to hit that right loop when lit to start modes. Good Luck, it is a fun game.
