If the strike program is going to survive I belive the casino's will just change the percentage chip so there are fewer strikes won. Changing to .900 silver won't get a true 10% reduction because the cost of .900 compared to .999 silver isn't 10% less, like I said in another post .900 silver is not as common as .999 so the cost isn't 10% less. The last I heard the casino's cost per strike was just under $10.00
