I want to offer a very simple game via CGI and don't know that much about it yet. Basically I need to randomly generate four choices from six colors (blue, green, red, yellow, brown, purple) without repeating colors then allow the user to choose four from the same list, again no repetition. Then a button to check the number of pegs in proper position and proper color AND a separate response for number of correct colors but wrong positions. Assume that the correct answer can be stored in a hidden field and users won't know how to cheat (children). Previous guesses don't need to be stored. Any help is appreciated, thanks.
