General Information

Rules Highlights

Compare 1841 to another 18xx game.

  • Major and minor corporations
  • Incremental capitalization
  • Corporations divided into historical and non-historical corporations
  • Historical corporations require a concession to start
  • Corporations can own shares in other corporations, and can even own other corporations (including starting them)
  • Corporations can buy placed tokens from other corporations during OR
  • Corporations choose number of, and pay for, tokens when they are started. For non-historical corporations, cost of tokens is determined by distance to existing track. Cost is fixed for historical corporations.
  • Non-historical corporations choose home city or cities when they are started. Fixed for historical corporations.
  • Map is divided by regional borders that shift as the game progresses
  • Cannot place a token unless it can be traced to another tokened city within the same region
  • "Passes" are tiles that can accept a token (for blocking), but don't generate revenue and are not starting points of routes
  • Can merge corporations if they connect without crossing a regional border
  • Can convert minor corporations
  • When 4 train is bought, certain historical corporations will split up or be merged depending on map state

Rules Clarifications

  • When selling stock during EMR, you are not required to sell all stock - just the amount required to buy the cheapest train from the bank. Except for having to sell all treasury shares before IPO shares, the player determines the order in which stock is sold. Reference.
  • When merging corporations, the newly formed corporation may only have as many tokens on its charter as the component corporations did. It may have less tokens on its charter if more tokens are left on the map.
  • The rules are silent on player bankruptcy when that player holds an active concession. See below for the "house rule" this implementation will use. The driving principle is that, prior to phase 4, the president certificate and the concession are never separated.
  • The rules are silent on player bankruptcy when buying a token. This should be an extremely rare occurrence.

Variants and Optional Rules

  • By default, this implements the Version 2 rules, corporations, concessions, maps and tiles.
  • By default, this does not allow direct player to player purchases.
  • Allowing player to player purchases is an option
  • Version 1 auction, corporations, concessions, maps and tiles is an option
  • The "Lite" game is an option. This reduces the size of the map, reduces the number of corporations, concessions and trains. It also removes the Tuscan Merge.
  • All of these options are orthogonal to each other and may be freely selected.

Implementation Notes

  • When trading between players, if you wish to buy the president certificate of a historical corporation before phase 4 you can do only this by buying the concession from the player
  • Merger price is set before exchanging shares
  • If there is a choice in merger price, it is made by the player that triggered the merger
  • Merger token selection is made by the president of the newly formed corporation
  • When merging, the game will let you remove tokens from the map 1) when the newly formed corporation would have more than five tokens, and 2) when removing tokens from the map would allow tokens to be placed on the charter instead of the map. As it is currently implemented, these are the only times when tokens can be removed. In the future, this may change to allow the new corporation to remove tokens that result in fewer total tokens than it would normally be allowed.
  • The rules state that if no shareholder is president of the corporation formed by a merger, the merger is to be "backed out". As as soon as this implementation detects that there is no president, an error will be generated. Your only choice is to convince someone to take the president's certificate or abort the merger entirely. Either will most likely require using the "undo" button.
  • If a corporation is subject to EMR when buying tokens at the point a corporation is started, the game will automatically sell (issue) shares to cover the required cost. However, EMR when buying tokens after transforming a minor to a major is not automatic - the player will have to sell any required shares in the same manner as during forced train purchases.
  • If a player holds a concession (i.e. before phase 4), they cannot sell the corresponding presidential share - even during EMR - except when bankrupting.
  • When a player that bankrupts is the owner of a concession before phase 4, the president share will be sold to the share pool (at half value as usual) and the concession moved to the bank (with no compensation) and the corporation will be marked as Frozen. In a future SR, the president share and concession may be bought as a package for L.50 plus twice the current share value and the purchasing player will become president. If phase 4 is triggered before this occurs, the concession is removed from the game as normal and if any player holds 20% (40% for minor) or more, they will become president and the corporation will unfreeze. If there is a tie for most shares, the player closest to the player that purchased the 4 train will become president. If no player owns 20% (or 40%), the corporation will remain frozen.
  • When a player bankrupts during EMR for token purchases (this should only be able to occur when transforming a minor), the player bankrupts as usual and the corporation is forgiven for any remaining cash needed for the token.
