Monopoly Ledger

Monopoly Ledger is a Web-based tool to support more diverse rules for Monopoly that are not easy to implement with cash.

This project is inspired by the original purpose of Monopoly's predecessor, The Landlord's Game, which was to demonstrate the effects of different economic rules. The use of a digital ledger also enables a wider variety of rule-sets than would be possible with cash.

How to Use It

Use Monopoly Ledger alongside the standard board game. It can replace the game's cash, though you will likely still need the property cards.

Because this tool is meant to facilitate play beyond the official rules of Monopoly, there are some terms used that may require clarification:

The Bank is an infinite source (and destination) of money without a fixed balance, as in the official rules of Monopoly.

Pot is a balance of money, often kept in the middle of the board. In common variants of Monopoly, various taxes and fees are paid there, and players can collect the pot upon landing on Free Parking. In the official rules, there is no pot. Here, it serves as an alternative to the Bank as a finite source of funds.

Rules listed on Monopoly Ledger should be understood to be additions to or replacements for the official rules of Monopoly. Unless otherwise stated under "Rules" here, follow the official rules.

Transactions to "All" enable players (or the Bank or Pot) to distribute a certain base amount of money equally to all other players. The funds are distributed sequentially, as if handing out one-dollar bills in order. This means the distribution may not be exactly equal, but it avoids the use of fractional quantities.

Levies are tax-like actions that remove a certain percentage of money from all players' money balances. A levy based on "Property Values" refers to both purchase value and improvements, while "Wealth" includes those Property Values plus money.

The Properties tool includes a field where users can add the value of the improvements made on their properties for the purpose of levy and wealth calculations.
