Opening Day Notes: Three Decisions Behind HoodRich

  HoodRich by the Numbers: What a Flip Pays and What Waiting Costs

The city opens on October 2. Before it does, we want to write down three decisions that define the game, and why each one is there. If you only read one post about HoodRich, this covers the thinking behind the rules.

Quick context for anyone new. HoodRich is a city of 33 towers on Robinhood Chain, each named after one of the world's biggest companies. You buy a tower with $RICH. Anyone can buy it from you for 30% more. You can't refuse, and you keep 15% profit if it happens within a day.


Decision one: prices fall


After 24 hours without a buyer, a tower's price drops 10% a day, down to its starting price at the lowest. It can look odd to build a way to lose into our own game. There are three reasons:


- Expensive towers don't get stuck forever, so the city keeps moving.

- Buyers get something to hunt for: towers that have gone cheap.

- An owner knows time is working against them and has a reason to act.


Without this rule the game would be a ladder that ends at the first price nobody wants to pay.


Decision two: quiet hours pay the most


Part of every purchase goes into the Vault. The Vault has a 24-hour timer, and each purchase adds an hour, capped at 24. When it hits zero, the last buyer gets half, tower owners share 20%, and 30% stays for the next round.


So the quieter the city gets, the closer the timer is to zero, and the more a single purchase is worth. A lull creates its own reason to act. The game wakes itself up.


Decision three: we gave up control


The contract has no owner. We can't change the rules, pause the game or take the money. We have no treasury. Rounds close without us: any player can close one when the timer is out. If the site goes offline, the game can still be played through a block explorer.


The trade-off is real. If we can't touch the game, we also can't promise anyone anything. Every coin a player receives was paid in by another player. There is no outside yield and no guaranteed return. Someone who buys at the peak and finds no buyer loses.


We would rather say that here than have anyone find out later.
