As reported by the Des Moines Register: “Betting by Minnesota gamblers has 
been so brisk at the Diamond Jo Worth Casino in north-central Iowa that 
state gambling regulators approved plans today for a major expansion project 
costing more than $20 million. “During its first three months since opening, 
the casino has drawn 335,000 customers who have left behind nearly $17 
million. Those figures are more than twice as much as industry researchers 
had forecast, Diamond Jo General Manager Jesus Aviles told the Iowa Racing 
and Gaming Commission. “…More than 70 percent of the customers are coming 
from Minnesota, he added. “.The Diamond Jo Worth Casino has 11 table games, 
plus 513 slot machines that are the most profitable of any of Iowa’s 15 
state-regulated gambling operations, state records show. Each of the Diamond 
Jo Worth’s slots are winning an average of $342 per day from gamblers, who 
are often waiting to play in lines three to four persons deep behind each 
machine.
“The casino, which is owned by Peninsula Gaming of Dubuque, opened in early 
April in an agricultural-themed $40 million gambling complex.
“.The plans approved by state regulators on Thursday include 30,000 
additional square feet of space that will provide room for 300 additional 
slot machines, 11 more casino table games, a 190-seat buffet, and a larger 
entertainment area. Aviles said he hopes construction can be completed later 
this year or early next year.”
