A method of remotely interfacing with at least one player in a rule-based game over a communication medium operatively connected to one or more communication devices including a visual display wherein each player is associated with a communication device, includes visually displaying at one or more of the communication devices a form comprising a two-dimensional matrix having a cell at the juncture of each row and column and where each cell may be manipulated to reflect a game choice by the player, retrieving by a server each game choice made by the player before any subsequent game choice is made by the player, applying the rules of the game to determine what further game choices are available to the player based upon the game choices retrieved, generating a revised form reflecting game choices made by the player and game choices which are available for the player to make, transmitting the revised form to the communication device being used by the player, and visually displaying the revised form at the communication device being used by the player.
