The Frontier has a 6 coin jacks or better (9/6) which was just hit at
over $7400.
That was more than 109%
There are high progressives out there, if you are looking.
Another casino had an 8 coin progressive dollar.
7/5 Bonus. 5-k started at $200, 2,3,4 at $320, Aces at $640, SF at
$400
They reset it to 5 coins but failed to reset the starting numbers of
the Quads.
A pro found it, and it cost the Caasino well over $20,000 before it
was found and fixed.
These are examples of good scouting. The plays are out there. They
must be found.
