You run REDCREST, a corner tobacconist. ADMIRAL sells to the same smokers.
It starts with one smoker on your street and grows to a national market. Whoever has more money at the end wins.
Each smoker buys the cheaper pack they can afford. Loyal smokers forgive a gap.
Every pack sold empties your shelf. Refill it by winning leaf at auction.
Both shelves are public. ADMIRAL can see when you are about to run out.
