These rules are for the same game as the main rules. Omitted, however, are numerous details that might distract beginners from the essentials.

§1 Introduction. When playing the CORPORATE GIGABUCKS board game, your object is to bankrupt your opponents before they bankrupt you. Key features:

• Throughout play, players buy and sell corporations.
• All purchases are made by way of auctions, which occur frequently.
• A corporation diversifies when it launches a new product line.
• Sometimes one player must pay royalties to another; corporations with many product lines earn larger royalties.
• Each corporation is housed on a space on the playing board; when the same player owns corporations in consecutive spaces, a conglomerate is formed, commanding higher royalties.
• A player who has insufficient assets to pay a royalty is bankrupt and retires from the game a loser.
• The one player who survives is the winner.

§2 Necessities.

A. Roughly four to eight players.

B. A playing board displaying a track on which are spaces representing corporations, each identified by number.

C. Charter documents, each a small card bearing the number of a corporation.

D. Currency representing gigabucks. The smallest denomination is $1,000,000,000 (one gigabuck).

E. Product line tokens (PrLiTos). These are placed on a corporation's space to show how many product lines the corporation has.

F. One player token (PlTo) per player, all different. A PlTo marks the player's current spot on the playing board.

G. One current player token (CuPlTo), for keeping track of whose turn it is.

H. A pair of ordinary dice.

§3 Assets. These are of two kinds:

A. Currency. After players receive their initial allotment of currency at the beginning of the game, all transfers of currency are from one player to another.

B. Corporations with their product lines; each product line is signified by a PrLiTo residing on the corporation's space:

• At the beginning of the game, no corporation has yet been chartered, in other words created.
• Once a corporation is chartered, it is never dissolved.
• When a corporation is chartered, it starts with zero product lines.
• Once a corporation adds a product line, it remains with that corporation until the end of the game, even if the corporation is sold.
• There is no limit to how many product lines a corporation might have.

§4 Preliminaries.

Each player receives an allotment of currency, a suggested amount being $300,000,000,000 (300 Gigabucks) per player.

Players by mutual agreement decide who will sit where, and which player goes first. The first player gets the CuPlTo.

§5 Course of play.

Players take turns, moving clockwise around the table. The CuPlTo is passed from one player to the next; this is important because with all the activity, it is easy to lose track of who the current player (CuPl) is. The details of the different kinds of auctions are given in section 6 below.

On your first turn, you simply place your PlTo in any vacant space, and call for a charter auction.

On your second and subsequent turns, you begin by rolling the dice and moving your PlTo the indicated number of spaces. Movement is toward increasing numbers, and space number 0 follows the highest-numbered space without complication. If the space to which you would move already has somebody else's PlTo, you move to the first vacant space after it. The location of your token is termed your current space (CuSp).

This is what happens after you move your PlTo:

• If you have landed on a corporation that is not yet chartered, you call for a charter auction.
• If you have landed on a corporation that is inactive because its owner resigned from the game before going bankrupt, you call for a reactivation auction.
• If you have landed on a corporation that you own, you call for one of these: a diversification auction, a voluntary liquidation auction, or no auction.
• If you have landed on a corporation that an opponent owns:
  • If you have enough currency to pay any royalties, you pay the royalties to the corporation's owner, and then you call for one of these: a diversification auction, a voluntary liquidation auction, or no auction.
  • If you do not have enough currency to pay the royalties, you call for one or more involuntary liquidation auctions until enough currency is accumulated, and then you pay the royalties to the corporation's owner. If you run out of corporations to sell before gathering enough currency to pay the royalties, you give such currency as you have to the corporation's owner, and you retire from the game bankrupt, a loser.

When your turn ends, you pass the CuPlTo to the player on your left.

§6 Auctions. Here are the details:

auctions in general	In every auction: Bidding starts with the player at CuPl's left, and continues clockwise around the table, the players in turn. Each bid must be a whole number of gigabucks, minimum $1,000,000,000, and each bid must be higher than the previous, except that any player may pass. Each player may bid multiple times, but once a player passes, that player is out of that auction.
charter auction (ChAu)	HiBi pays the winning bid amount to each opponent. HiBi becomes the owner of the corporation and receives the charter document for the space that CuPl's token is resting on.
reactivation auction (ReAu)	This works the same as a ChAu. The corporation retains any product lines it already had.
diversification auction (DiAu)	HiBi decides how many product lines to buy, and announces the number, the minimum being one. HiBi pays to each opponent the winning bid amount multiplied by the number of product lines being purchased. Then HiBi adds PrLiTos to those corporations that HiBi wants to diversify.
voluntary liquidation auction (VoLiAu)	CuPl specifies what corporation(s) are to be sold. It might be one specific corporation, a combination of several specific corporations, or the right to choose one or more corporations from a list that CuPl announces. CuPl can specify a minimum bid. HiBi pays the amount of the bid to only CuPl, and receives charter document(s) for the corporation(s) in question.
involuntary liquidation auction (InLiAu)	CuPl reveals the charter documents of all the corporations that CuPl owns, and the other players bid for the right to buy exactly one of CuPl's corporations. HiBi pays the amount of the bid to only CuPl, and receives the charter document for the corporation of HiBi's choice, which may be any corporation that CuPl owns.

§7 Royalties. When CuPl lands on a corporation owned by an opponent, royalties must be calculated. When CuPl lands on one space of a conglomerate, the calculation of royalties involves all of the conglomerate's corporations:

• $1,000,000,000 is due for each product line of the CuSp's corporation.
• If the CuSp is part of a conglomerate, more royalties are likely due. For each other space (OtSp) in the conglomerate, the royalty is calculated as $1,000,000,000 multiplied by the the minimum of:
  • the number of PrLiTos on that OtSp
  • the number of PrLiTos on the CuSp
  • the number of PrLiTos on each space between the OtSp and the CuSp
  All these individual royalties are added to form the total royalty, and that is what CuPl pays to the owner.

§8 Resignation. If a player quits the game before going bankrupt:

The resigner's currency is divided among the remaining players as far as it will go evenly. Any remainder waits until the number of players in the game has been reduced to the point where it equals the number of gigabucks in that remainder.

The resigner's corporations become inactive. When a player subsequently lands on an inactive corporation's space, no royalties are paid. Instead, CuPl calls for an ReAu. The corporation retains all its product lines throughout.

§9 Talk. Open discussion is always permitted, no matter whose turn it is, as long as it does not interfere with the game action. A player may suggest to another some particular course of action; or may announce an intended course of action for self, even going so far as to propose a specific deal.
