Turn structure
On their turn, a player must place exactly one tile onto its matching board space.
Each turn, a player must place exactly one tile from their hand onto its corresponding space on the game board. The tile's position relative to other tiles on the board determines the outcome: it may be an isolated tile (no immediate effect), extend an existing corporation, found a new corporation, or trigger a merger. The placement step is mandatory and occurs before buying stocks.
Building
Placing a tile orthogonally adjacent to a lone tile (not part of a corporation) founds a new corporation, if any corporation markers are available.
If a player places a tile that is orthogonally adjacent (up, down, left, or right — not diagonal) to one or more tiles that are not currently part of any corporation, and at least one corporation building marker is available in the tray, a new corporation is founded. The player takes one available building marker and places it on one of the tiles of the new corporation to designate it. As the founder, the player earns one bonus stock certificate in that corporation from the bank, if any shares remain available.
Building
Placing a tile orthogonally adjacent to an existing corporation adds that tile to the corporation, growing it by one tile.
If a player places a tile orthogonally adjacent to tiles that are already part of a single corporation (and the placement does not connect two or more separate corporations), the placed tile is simply added to that corporation, increasing its size by one tile. No special action is required. The corporation's stock price may change based on its new tile count, as reflected on the information card.
Special
Placing a tile that connects two or more corporations triggers a merger; the largest corporation absorbs the smaller one(s).
If a player places a tile that is orthogonally adjacent to tiles belonging to two or more different corporations, those corporations merge. The corporation with the most tiles is the surviving (acquiring) corporation and absorbs all smaller (defunct) corporations. If two or more corporations are tied for the largest size, the player who placed the merging tile chooses which corporation survives. The building marker(s) of all defunct corporations are returned to the tray. The merger is fully resolved — including shareholder bonuses and stockholder decisions — before the active player proceeds to buy stocks.
Scoring
During a merger, the player with the most shares in the defunct corporation earns the majority shareholder bonus.
When a corporation is made defunct by a merger, the player holding the greatest number of shares in that defunct corporation earns the majority shareholder bonus. The bonus amount is determined by the number of tiles in the defunct corporation just before the merger, as shown on the information card. If only one player holds shares, that player earns both the majority and minority shareholder bonuses.
Scoring
During a merger, the player with the second-most shares in the defunct corporation earns the minority shareholder bonus.
When a corporation is made defunct by a merger, the player holding the second-greatest number of shares in that defunct corporation earns the minority shareholder bonus. The bonus amount is determined by the number of tiles in the defunct corporation just before the merger, as shown on the information card. All other shareholders (those who are neither majority nor minority) receive nothing from the merger bonuses.
Special
If two or more players tie for the most shares in a defunct corporation, the majority and minority bonuses are combined and split equally among the tied players.
If two or more players are tied for the highest share count in a defunct corporation, the majority shareholder bonus and the minority shareholder bonus are added together, and the total is divided equally among all tied players (rounding in favor of whoever the game convention dictates, typically rounded to the nearest payable denomination). No minority bonus is separately awarded in this case — it is already included in the split. If players tie for second place (minority), those tied players split only the minority bonus equally between them.
Special
After a merger, each player holding shares in the defunct corporation must choose to hold, sell, or trade each share (options can be combined).
After shareholder bonuses are paid, each player holding shares in the defunct corporation decides what to do with those shares. Players may use any combination of the three options for their shares:
• HOLD: Keep the stock certificates. They retain no current value but can be held in anticipation that the corporation is re-founded later in the game.
• SELL: Sell any number of shares back to the bank at the price shown on the information card for the defunct corporation's tile count at the time of the merger.
• TRADE: Exchange defunct corporation stock for surviving corporation stock at a rate of 2 defunct shares for 1 surviving corporation share, subject to availability of surviving corporation stock.
