As the year draws to a close (whether your days are growing shorter and darker or longer and brighter), December tends to invite a little reflection. Over the past year, Planet Mainframe Trivia has dished out a veritable smorgasbord of topics, from the early days of the platform and its appearances in pop culture to today’s conversations about cybersecurity, cloud integration, and AI-driven innovation.

This quiz is a sort of sampler platter of that journey (to mix our metaphors). It pulls together questions from across the themes we’ve explored, with no strict order and no single focus—just a broad mix designed to jog your memory and test what stuck. Consider it a year-end check-in with the stories, concepts, and moments that shaped our coverage, offered in the spirit of curiosity, fun, and keeping you on your toes.
