Upgrading Properties
Time it took Matthew: 50 mins
Feature Description
Whenever a player has the ability to roll dice or leave the game they also have the ability to purchase or sell upgrade on any property within in a set that they fully own. A player can purchase or sell as many upgrades as they want during a turn. When a player upgrades a property they add one house to it. If the player has enough enough houses as specified in the rules file and they upgrade their property, the houses are removed and a hotel is added in place of them.
Requesting an upgrade
During a player’s turn they may press 2 to upgrade a property. If they choose to upgrade a property all of the properties on which they can upgrade should be displayed to them. A property is upgradeable if
The user owns all of the properties in the set
The user has enough money to purchase the upgrade on that property
If the “Must Build Evenly” rule is set then only the property within a set that has the fewest upgrades may be upgraded
Properties should be shown from lowest property id to highest and within a set from lowest intraset id to highest. After each property display the upgrade cost in [] For example if the
player owned Oriental Avenue, Vermont Avenue, Connecticut Avenue (set id 1) and Park Place and Boardwalk (set id 7) then they would see the following when upgrading a property
Which property do you want to upgrade?
Oriental Avenue [$50]
Vermont Avenue [$50]
Connecticut Avenue [$50]
Park Place [$200]
Boardwalk [$200]
Your choice:
If a user does not have any properties that they can upgrade they should be shown "You don't have any properties that you can upgrade"
Purchasing a property does notend a players turn or advance the turn count.
Selling Upgrades
During a players turn they may choose to sell a property back to the bank for half the cost they purchased it at by pressing 3. The interface for selling an upgrade is the same as for purchasing an upgrade but instead of saying Which property do you want to upgrade? instead say Which property do you want to sell? If the player has no upgrades you should say: You have no upgrades to sell.
If the Must Build Evenly Rule is enabled, the player may only sell upgrades from properties within a set that have the most upgrades on it.
If a player would go bankrupt to a player during their turn but they have upgrades on a property, they must sell their upgrades back to the bank. They must continue selling upgrades back to the bank until they either have enough money to pay off their debt or they have sold all of their upgrades. If at this point they are still in debt, they then go bankrupt.
Calculating rent
Rent for a property that has houses on it as calculated as
rentF orOneHouse * 2NumberOfHousesOnT heP roperty − 1 . Rent for a hotel is the the rent for the hotel as given in the board file.
Calculating Net Worth
A players net worth is now the sum of their cash, the cost of their properties, and the cost of the upgrades on their properties.

Rolling Again on Doubles
Time it took Matthew: 20 minutes
Feature Description
Whenever a user rolls doubles (both dice have the same values) they roll again up until they reach the Max Doubles ReRolls limit specified in the rules files.
Updates to Rules Files
There is now a new entry in the rules file at the end called Max Doubles ReRolls. It
has the form Max Doubles ReRolls: N, where N is the maximum number of times the user gets to roll again if they roll doubles on their turn. If it is 0, then if they roll doubles they don’t get to roll again. If 1 they can roll again once, 2 twice, 3 three times, etc. They only get to keep rolling on their turn IFthey keep rolling doubles. For example, if N is 3 and the user rolls two 3’s they get to reroll. If they then roll a 5 and a 4 their turn is over because they did not roll doubles.
Auctioning Properties
Time it took Matthew: 30 minutes
Feature Description
If the Auction Properties rule is enabled and player lands on property and chooses not to buy it or is unable to buy it, the property goes up for auction. The auction starts at $1. Players take turns bidding on the property starting from Player 1. A player must bid at least one more dollar than the current max bid. If a Player does not wish to make a bid then they can enter a number less than the next bid to remove themselves from the auction. If a player’s total cash is less than the next bid they are automatically removed from the auction. Bidding continues until only a single player is left in the auction. They are the winners of the auction and get the property for the price they bid on it. If all players decline to bid on the property it remains unowned.
Interface
When an auction starts you will display
