• FUN & ENGAGING GAMEPLAY – SUMIGI, is a fast-paced math card game. Players hold blue cards (addends and special twist cards) and race to use them to close matching red target cards (sum cards) on the table. The first player to close all of their red cards wins. SUMIGI takes only 3 minutes to learn and uses special cards to keep every round unpredictable, turning math into lively, screen-free fun for kids while giving adults a dynamic strategic challenge.
• EDUCATIONAL BENEFITS – Created by a couple of scientists and educators with their child, SUMIGI reinforces 1–10 addition tables while building math memory, problem-solving, and strategic thinking. It offers a fun, screen-free way to boost math confidence and keep kids excited about learning.
• PERFECT FOR FAMILIES & CLASSROOMS – Designed for ages 8+, SUMIGI bridges the gap between learning and entertainment and keeps adults engaged while kids strengthen their math skills.
