Math Grid turns the classic Japanese "hyakumasu keisan" (100-square calculation) into a joyful daily habit. One operation in the corner, numbers across the top and side — your child fills every square, beating their own best time. BUILT FOR AGES 5-7 (AND UP) - Four operations: addition, subtraction, multiplication and division - Grid sizes from a friendly 3x3 up to the legendary 100-square - Auto mode quietly adapts the difficulty: two strong rounds move up a level, a tricky day gently adjusts down - never framed as failure - Tricky facts quietly reappear in new grids until they are mastered FRIENDS AND LEADERBOARDS - Add a friend with a simple friend code (you both accept) and compare your weekly and all-time stars - See who is online with a friendly presence dot - Family leaderboard: star champions and fastest fingers BATTLE A FRIEND Race a friend on the very same grid: - Challenge an online friend into a live battle with a single tap - Online Battle: open a room with a 6-digit code and play in real time. If no one is online, a friendly practice opponent steps in. - Code Battle: finish a round to get a secret code you can send to a friend so they play the identical grid offline - fastest time wins. THIS WEEK'S CHALLENGE Each week features a friendly challenge - a trickier operation or a bigger grid to give a go. Try it and earn extra stars for having a crack. A gentle nudge to explore the harder squares, never a chore, and never any pressure to keep a streak. MADE FOR FAMILIES - Up to 6 player profiles, each with their own avatar, colour, progress and streaks - A practice calendar that glows brighter the more stars you earn - Parent dashboard (behind a grown-up gate): accuracy charts, level overrides, tricky-facts list PRIVATE BY DESIGN Your child's progress stays on their device. Math Grid has no ads, no third-party analytics, no tracking and no account. The only data that ever leaves the device is for the optional online features: an Online Battle shares just a first name and avatar to run the live match, and the Friends feature shares a first name, avatar, colour, star counts and a simple online/offline status - only with friends you have both accepted. Purchases, external links and sharing sit behind a parental gate. FREE TO PLAY 3x3 and 4x4 grids, all four operations, Auto mode, battles, friends and 3 profiles are free forever. Math Grid Premium unlocks 5x5 and the full 100-square, manual level picking and premium avatars. The Family plan adds up to 6 profiles with Family Sharing.
