Version 1.07 2022-01-02

Fixed a problem with bank auctioning a Railroad. Because it is the only monopoly group with 4 properties, there was an error that the first player to fold, that the property was sold to the folding player at the fold amount.

Fixed a problem with a player forfeiting an entire monopoly group to another player and the player receiving the entire monopoly group not having the group marked as a monopoly for the receiving player because it was already marked as a monopoly for the forfeiting player. This prevented the receiving player from purchasing houses for that property. The monopoly marker has now been moved properly to the correct player

Added /salarymult= for an additional multiplier for landing on go. This is a popular feature of online monopoly games.

There is now board versions of MonoPlus. So far the only working board version is UK because of English. /version=UK I will have the option of other countries where only the properties are of that country and then a option to play the entire game in that language as well. Board versions only work with the /game=classic option.

Scenario's are now loadable into MonoPlus. Two loadable scenario's are now included in the zip file. Each line is for a consecutive player up to /players= number. You can load the player's initial properties, initial cash and initial starting position. More information is in the included scenario text files.

Version 1.06 2021-12-24

Fixed a problem with property ownership if a player becomes bankrupt via a Chance or Community Chest card, the bank auctions the property to the highest bidder. The bank then removed that bid amount from the bidder, assigns the player as bankrupt and assigns that bankrupt player the owner of the property instead of the winning bidder. That prevents the property from being used in the game and all further players in the game landing on that property, money is paid to the bankrupt player. This has been fixed and is now properly assigning the auctioned property to the winning bidder.

A results.txt file has also been created at the end of the game to see what happened.

I have also fixed the player limitation by not allocating all player memory at the start of the game. Player memory is now allocated dynamically and freed when no longer needed. On my 4Gb of ram machine, I now can have 2000 players instead of the 600 before when allocating memory at the start of the game.

Version 1.05 2021-06-05

Inflation comes to Monopoly. In some circumstances properties can be distributed equally to where there can  be no clear winner in the game and each player is paid more money than they lose on each go around the board.  This can be solved by limiting the number of turns in the game(/turnslimit) or you can turn on inflation(/inflation) which the percentage of inflation keeps on rising when ever the bank balance goes negative and the bank starts printing money. Turn on inflation that keeps making everything more expensive to see how the player with the most assets when inflation kicks in, will benefit the most and win the game.

Version 1.04 2020-10-07
