Tintown

In a bar, a mysterious stranger told the bartender a bizarre story to trade for alcohol:
A gambler encountered a scam at a game booth that played with stones. Afterwards, he trailed the booth owner, a blind man, to an isolated village.
The villagers gathered in a small teahouse, also playing a game with stones. The gambler gradually discovered that the villagers were color-blind, and he could easily win the game by distinguishing the color of the stones.
Just when the gambler was eager to try, the woman who ran the teahouse repeatedly drove him away, as she seemed to know his secret. The gambler ignored the woman’s warnings, and eventually brought himself catastrophic troubles.
