Card Game / Board game: IPO

The other week while playing around with game mechanics I came up with a little card game.  It is short (around 10 minutes) and uses pieces that many board gamers probably already have.   The mechanic that made it interesting for me was when playing cards on the table sometimes it is face up and everyone knows, but other times it is face down and only you know the value until the end.


- A standard deck of cards
- Any Dominion set (really just a bunch of sets of matching cards)


Win by collecting stock in the most valuable companies.

A company is a set of action cards from the Dominon game

The companies value is the total of the playing cards in front of the company.  Black numbers are positive, red are negative.

At the start of the game there are 1 more companies than their are players (so 2 players starts with 3 companies open) and each player gets 5 cards.

On your turn you place a card from your hand, optionally take a stock from any open company and then take another card from the deck.

When playing a card the following rules apply:

  • 2-10 cards that must be played on a company.
  • A Play this to open a new company.  The player gets a bonus of 1 stock in the company they opened.
  • K Play this card to merge two companies.  The K card is discarded and the stock piles and value piles of any two open companies are merged into one.
  • J,Q Play this to close any one company (unless it is the only company open).  No one can take stock from a closed company.  Closing a company is its IPO

When you play a 2-10 card on a company it must be facing the opposite direction of the last card played on that company.  The first value card played on a company can go face up or down with the player deciding.

Game End

The game ends when the deck of shuffled cards is used up.  Add up the total value of each company.  For each company player multiplies that number by the number of shares they have to get their total.  Add up all of the company totals to get a players score.  Highest score wins.
