Cheese Factory

Cheese Factory is a Secondary Industry card in Machi Koro, available in the base game.

Gameplay
When the card's activation number of 7 is rolled, the player with the card gets three coins from the bank for each card with the icon he owns, on his turn only. Currently, the only card with a icon is Ranch.

Strategy
The per-turn expected value of the card depends on whether the player uses the Train Station establishment to roll two dice, and how many Ranches they own (here represented as "rch"):

Or:

The card's value is multiplied again by how many Cheese Factories the player owns.
