The Spellbook is a 3D animated adult adventure made by NaughtyGames in Unity. It begins when a book is found by accident and a spell is cast without thinking, starting a risky story about choices. You play someone who finds the book and must choose how to use the magic on the women around you, trying to make them fall for you or risking failure and loss. The game focuses on choices, with themes such as corruption, cheating, and female domination.
The current build is v0.20.0.0, released July 1, 2023, and the changelog shows continued development. It runs on Windows, Mac, and Linux in English, with no censorship. The latest update added about 4,000 words, 124 images, and 14 videos. The version is not marked final.
