Based on The Lion, The Witch, and The Wardrobe by fantasy author, C.S. Lewis, Adventures in Narnia is a family-oriented "interface" game that incorporates cards and dice into the video gaming experience. The goal isn't to kill aliens, bad guys, or monsters, but to reap rewards for positive behavior such as resisting temptation. The game aims to teach values like the importance of self-sacrifice, and calls on players to choose alternatives.

As the game begins, the Witch has frozen Narnia and sent out her evil dwarves to occupy and patrol the area, stomp on any flower or beaver that gets in their way, and try to prevent you from gaining strength. For each beaver you touch, you receive a unit of strength in the form of a heart. As you collect hearts, Narnia begins to thaw and turn green. Touching flowers will net you 100 points apiece. From time to time, you must intercept Edmund who is powerless against the witch and will go to her if you do not stop him.

If you're hit by a Dwarf or moving bush, you are sent to a Dwarf Battlefield. Here, you play a dice game where the Dwarf "thinks" of a random number between 2 and 12; the number you roll must be higher. If your number is lower, you lose a heart. Adventure One ends when you get 10 hearts, the witch captures Edmund, or time runs out.

Adventure Two takes place in an Ice Maze where you must reach the noble lion Aslan. The Witch sends evil crystals to stop you. Get hit by one and lose a heart. You can collect flowers for extra points. The maze contains three snowy Gravity Chutes, which, when you step into them, send you to the bottom of the maze. Run into a door and you are sent to a Card Sub-Adventure.

There are a variety of dice games in the Card Sub-Adventure to challenge your luck and decision-making skills. For example, Fenris Ulf, the wolf, dares you to roll odd numbers while Jadis, the witch, challenges you to beat your first roll of the dice with the second. The card you draw instructs you which game to play and you can even draw bonus cards!

At the end of the instruction manual for Adventures in Narnia, you will find a section for parents and teachers. These pages propose questions to ask children about the game and offer ideas for enrichment activities such as drawing a map of Narnia and acting out scenes of the game after the game has been played. ~ Brett Alan Weiss, All Game Guide
