Interactive educational games are provided that include adventure storylines in which a player advances, scores points, or wins by correctly answering challenges (e.g., questions related to math skills or word construction skills, etc.) posed throughout the game. The game gauges and dynamically adjusts a player's skill and knowledge level for a particular subject (e.g., math, grammar, spelling, science, etc.) to tailor the challenges and/or speed of the game accordingly. As the game progresses, it monitors the player's progress in terms of skill and/or knowledge level and dynamically adjusts the type and/or difficulty of the questions to challenge the player. A centralized website is also provided with a secure authentication method to enable players to report their gaming records and obtain codes that adjust the operation of their game.
