If you dismiss a pinball machine because Keith Elwin exploited the scoring you'll probably never play again.

He was world champ so many times he got bored. I doubt you could replicate his scores even if you played with the glass off.

Not broken. You can (theoretically) score up to a 300 million point jackpot in BURNOUT Multiball if you have 3X scoring activated.

100 million+ jackpots in Mustang are difficult for mortal pinball players. Just another day at the office for Keith Elwin though.

Since I am a mediocre player, that score that Keith Elwin earned is amazing, jaw dropping, and I add, "I'm not worthy". He had 500,000,000 on the start of the third ball.

I've got to Silver Ball Stampede only twice, since setting this game up. To bad the video didn't go longer, as the pin turns all the lights to a purple-grayish colour. You will notice that right away. Scores over 100,000,000 for me are 2 in every ten games.

Is there really a 3x ?
Or maybe a typo (2x) ?

There is a 3x. Its when you get Super Nitros.
