Before you read this articleyou will need to know the following terms and definitions: 

Game(-s): Noun. Singular or Plural. A standalone version of Settlers of Catan, which can be played right out of the box without making additional purchases. There is only one standalone (base) game of Catan.
Expansion(-s): Noun. Singular or Plural.  An Catan game that cannot be played by itself. It must be used in conjunction with a standalone (base) game. The 5 & 6-player expansions are a good example of this.
Scenario(-s): Noun. Singular or Plural. A small set of playing pieces and instructions that can be added to normal Catan gameplay. It cannot be played by itself--it must be used in conjunction with a standalone (base) game. The "Oil Springs" scenario is a good example of this.
Variant(-s): Noun. Singular or Plural. A set of instructions for using the pieces from a Catan game or expansion in a new way. Most variants are fan-generated and require printing and cutting out new pieces.



You may purchase various items on your turn after you have resolved the Event Card Production Number.  To purchase anything, you must turn in the specified combinations of resource/commodity/spice cards/tokens (see the Building Costs Cards).  Return any spent resource/commodity cards to their appropriate supply stacks, and return any resource/commodity tokens to their appropriate supply piles.  Return any spent spice cards to the spice card supply stack by reshuffling the entire stack.

You may purchase as many items as you desire—as long as you have enough resources and commodities to “pay” for them, and as long as the desired items are still available in the supply.


In general, the following applies:

  • Commodities purchase development upgrades, transportation, wonder building cards, and other commodity/resource cards
  • Oil moves and buys some types of transportation, purchases building upgrades, and buys other commodity/resource cards
  • Resource Cards and Wooden Tokens are treated identically when buying building upgrades, Infrastructure, Transportation, and other commodity/resource cards
  • Wooden Tokens may be combined with cards to buy and trade during a game. Basic 4 - 1, 3 - 1 or 2 - 1 trades with the bank yield only cards, not tokens. However, tokens can be used in combination with cards as the items to be traded.  The tokens must match the cards.
  • When returning resources to the bank to satisfy the "greater than 7 cards" or “monopolization” penalty, the player can optionally discard a token that matches a card rather than discarding the card itself. In other words, the debt can be paid off with a mix of cards and tokens, as long as the tokens match individual cards that could have been discarded. This makes wooden tokens much more valuable and reduces the devastation caused by rolling a 7 or playing a monopoly card.



Create new flipcharts with new building costs, powers, victory points, fish exchange rates, gold exchange rates, and oil usages. Oil and fish should be treated more like commodities, but gold should be just a medium of exchange.  Make it clear how much gold can buy everything.

(Note: The resources to build basic items and level 2 upgrades denoted by * must be harvestable by settlements.  Level 3 upgrades and beyond may use commodities.
