I don't understand the argument that the IGT wants to pull the $200 strike because they don't make money off the recycled $10 strikes. Seems to me they make more if they have the $200.

If a someone is collecting strikes, and a machine only has one variety of $10, then they might play for one and stop. IGT makes profit off one $10 strike. If there is a $200 available, then they might play for 21 $10 strikes. They keep one and turn in the other 20. IGT makes profit off one $10 strike and one $200 strike. Net profit is higher.

If the player is not a collector, but just playing to redeem any $10 strikes at the cage, then it doesn't matter if there is a $200 or not.

The only issue I see is if there are a lot of hoarded $10 strikes that are all turned in when a new $200 is released, and then for some reason those $10 strikes become obsolete and have to be destroyed.
