Quoted from Pinslot:especially with the 2x bonus freebie on ball three that gives stragglers a chance to catch up.
Gottlieb did that with quite a few EMs, if I recall correctly. Cleopatra does it, and Big/Hot Shot does it as well. I always liked it. Since it makes the first 2 (or 4) balls strategic, but then the last ball is just a free-for-all hit everything fest.
