Fill the diamond: each number comes from the two next to it. Logic, no guessing.
Math Rhombus is a number puzzle on a diamond of diamonds. The middle row holds a few numbers. Every cell above it is made from the two cells just under it, and every cell below it from the two just above it. Find the missing numbers and fill the whole diamond. HOW IT WORKS • In the first world, each number is the sum of the two next to it: 3 and 5 make 8. • Each world has its own rules: adding, the difference between two numbers, multiplying. • Every puzzle has exactly one answer, and logic always gets you there. You never have to guess. 5 WORLDS, 150 LEVELS • Mirror: add up, add down • Difference: add up, subtract down • Big Diamond: bigger diamonds, longer chains • Product: multiply up, add down • Master: mixed rules, fewer clues Each world has 30 levels, from a few blanks to almost empty boards. Earn up to 3 stars per level and open the next world. HINTS THAT TEACH Stuck? A hint fills in one number and shows why: the rule in words, the equation and the three cells involved, outlined on the board. 15 = ? + 8 → ? = 15 − 8 = 7 You learn the step, not just the answer. PLAY YOUR WAY • Three looks: Gem Quest (bright and chunky), Paper Logic (calm and clean) and Neon Prism (dark and glowing) • Check numbers as you type, or only when you tap Check • Undo, erase, and a timer for your best runs PLAY TOGETHER Several people can share one phone. Each player has a nickname and their own stars and levels, and a leaderboard shows who is ahead in every world.
