Starts with interview with Jean Scott sitting at a multistrike machine somewhere in Vegas discussing Mount Airy.
Ends with statistics on Pennsylvania including:
"...State taxes take 55 percent of that gross slot machine revenue the amount left after all payouts.
Since the fiscal year started in July, the statewide payout rate is 90.1 percent; for every $100 bet, the machines return $90.10..."

The state tax in Pennsylvania is 55%. The slot hold is ~10%.
The state "tax" in Ct is 25%. The slot hold is between 8 and 9%.
Massachusetts is (tentatively) going to be 25%.
