The Encyclopedia Anachronistica is the companion reference for Time Rift, designed to give players and students quick, punchy insights into the historical figures, artifacts, and events featured in the game. Rather than presenting dry textbook entries, it blends accurate historical context with pop‑culture energy, making each card’s background accessible and engaging. The encyclopedia helps situate Champions, Artifacts, and Events within their real-world timelines, while also sparking creative connections across cultures and eras. Importantly, it is presented in a safe, school‑friendly location, ensuring that students can access reliable historical information without encountering the adult or off‑topic material that often leads schools to block sites like the wonderful resource of Wikipedia. In practice, it serves both as a lore book for gameplay and as an educational tool, scaffolding classroom activities with concise, memorable explanations that invite debate, synthesis, and imaginative mashups.
Explore information and history of past and present Time Rift cards in an interactive catalog. This catalog is updated regularly, so be sure to check back in when new sets and cards are revealed.

‘I am a teacher and I casually introduced the game to a few students and they loved it. Another idea could be starting in school contests for the students to participate in with fun/educational prizes.’
‘...my students love the game. I teach sophomores and juniors at Sumiton Christian School in Sumiton, Alabama, and I regularly have students stay after school in my classroom to play a few games. Some of these students have even picked favorite cultures and have taken the time to research them for their selves. It has fostered learning more than any other extracurricular activity that I have tried. Thank you for creating such a dynamic and intriguing game.’
‘I have taught 4 periods of AP World History how to play and we are currently having tournaments in all four periods I teach. If you ever need me to submit a lesson plan, let me know...It is awesome to share this game with my students!’
