You are a railroad owner who just started his company.
You have 13 stocks to sell in order to amass capital and build rails to 10 different cities.
Owners start has CEO of their company, but eventually, another player will take control of the company.

Each round, players secretely choose one company from which they'll take one share.
Shares are not actually "sold": players take the share and in exchange, the company gets cubes (tracks) that they will place further in the round.
The number of cubes is printed on each share.

Then, companies need to place the cubes they gained in order to build tracks between two cities: one is the "source" city and the other is the "target" city.
Companies need to build the most effective route to the "target" city.
If a company reaches it's "target" city, dividends are paid out to the shareholders, CEO and owner of the company as well as a payout for the company itself.

If a player has more shares/stocks of a company than the company itself, then there's a new CEO who controls the track building for that company.
A player can also "steal" the company from another player if his shares are more valuable than another CEO.

The game ends when one company has built into 6 cities.

Companies then split their assets between shareholders, CEO and owner.

The player with the most money wins.
