Hidden Sums is a word search where the words are math. Each round gives you a target number and a chalkboard grid of digits and signs. Hidden in the grid are lines of squares that add, take away, multiply or divide to make the target. Drag across a line to check it: if it makes the target, it's looped in chalk. Find them all to finish the round. LEARN THE SIGNS ONE AT A TIME The first rounds use only +. Then − joins in, then ×, then ÷. After that, the grids grow from 7×7 to 10×10 and the targets climb from 50 all the way to 1000. MADE FOR CURIOUS KIDS • Hand-drawn chalk numbers, loops and sounds • Hints show the first character of an answer, then where it starts • Easy, Medium and Hard answer lists, so the whole family can play • Earn up to three stars a round, and a badge for every chapter of ten rounds • Stop any time: your place in a round is saved FAIR FOR PARENTS • The first 30 rounds are free • One purchase unlocks all 200 rounds, plus every new round added in updates • No ads, ever. No accounts, no tracking, no data collected • Purchases are behind a parental gate • Family Sharing: buy once for the whole family • Plays offline It's real math practice (mental arithmetic, number sense, and the order of operations, with × and ÷ before + and −) disguised as a treasure hunt.

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• Nine rounds have new grids, so every answer can only be found in one place: rounds 11, 23, 44, 79, 118, 119, 139, 157 and 180. If you're partway through one of them, your stars are kept and the round starts fresh. • Small fixes and improvements.
