Hasbro has shut down web games in the past like e-Scrabble and Google Maps Risk, so you have to be careful. Before launching Conquer Club I met with a trademark lawyer to make sure everything is kosher.
Here is some backround info on
US Copyright law on games and
Canadian copyright law. A couple snippets from these sources:
US Copyright Office wrote:The idea for a game is not protected by copyright. The same is true of the name or title given to the game and of the method or methods for playing it.
Copyright protects only the particular manner of an author’s expression in literary, artistic, or musical form. Copyright protection does not extend to any idea, system, method, device, or trademark material involved in the development, merchandising, or playing of a game. Once a game has been made public, nothing in the copyright law prevents others from developing another game based on similar principles.
Some material prepared in connection with a game may be subject to copyright if it contains a sufficient amount of literary or pictorial expression. For example, the text matter describing the rules of the game, or the pictorial matter appearing on the gameboard or container, may be registrable.
Canadian Intellectual Property Office wrote:Trade-marks are used to distinguish the goods or services of one person or company from those of another. Slogans, names of products, distinctive packages or unique product shapes are all examples of features that are eligible for registration as trade-marks. Sometimes, one aspect of a work may be subject to copyright protection and another aspect may be covered by trade-mark law. For example, if you created a new board game, you might enjoy a copyright on the artwork applied to the face of the game board, the rules of the game and a trade-mark for the game's title.

When copyright does not apply
...
You may have a brilliant idea for a mystery plot but until the script is actually written, or the motion picture produced, there is no copyright protection. In the case of a game, it is not possible to protect the idea of the game, that is, the way the game is played, but the language in which the rules are written would be protected as a literary work. Copyright is restricted to the expression in a fixed manner (text, recording, drawing) of an idea; it does not extend to the idea itself.
Hope that answers some of your question
