The MATEMATIGI COLLECTION is a set of three math card games designed for both kids and adults, blending learning and strategy into fast-paced, screen-free fun. It brings together 1) SUMIGI, 2) MULTIGI, and 3) FAKTORIGI in a 4) COLLECTION BOX, offering the complete Matematigi experience in a single, organized set. Players race to match blue number cards to red target cards through addition, multiplication, or prime factorization, turning math practice into exciting, screen-free gameplay that’s easy to learn yet strategically engaging. The collection follows a progressive learning path, advancing from early addition to multiplication and prime number factorization, so it grows with children’s math skills. Created by scientists and educators for families and classrooms, it strengthens math fluency, memory, and problem-solving in a fun, competitive way. Purchasing the full MATEMATIGI COLLECTION is more economical than buying the three games and collection box separately, making it the ideal choice for families, teachers, and math enthusiasts. The complete set inside the collection box includes 480 colorful cards (160 per game) and rulebooks, all packaged in sturdy, gift-ready boxes for organized, long-lasting play.
