Enigma puzzle gamebooks are interactive stories where the reader actively participates by solving puzzles to progress. You've been summoned to Castle Slogar to celebrate Melissa's 9th birthday...again! But the party has gone awfully awry. Guests are scattered throughout the labyrinthine castle, and Lord Slogar is missing! It's up to you to lend a hand, or a foot, or whatever you can spare to save the party and rescue Lord Slogar.
