Math Puzzle Games - Crossmath®

Crossmath is a free math puzzle game from Guru Smart Holding Limited that tasks players with filling in number grids using addition, subtraction, multiplication, and division. It enforces proper order of operations, meaning multiplication and division resolve before addition and subtraction. Released mid-2023 and sitting on a remarkably high 4.94 store rating across 249,000 ratings, it positions itself as a low-pressure brain trainer with selectable difficulty levels that can scale to your comfort zone.

The Core Mechanic

The crossword-style grid format is a genuinely clever delivery vehicle for arithmetic. Because the game enforces real order-of-operations rules rather than simple left-to-right evaluation, there is actual mathematical thinking involved, not just number guessing. Easier settings keep the numbers small and the operations familiar, while harder difficulties layer in more intersecting equations, which means a single wrong digit can collapse multiple rows and columns at once.

Where It Gets Complicated

At 193 MB, the download feels heavier than the concept warrants, suggesting a fair amount of that space goes toward monetization infrastructure rather than puzzle content. The app is free with in-app purchases, and the experience of hitting paywalls or ad breaks mid-session is a realistic expectation here. The store description is also notably sparse on specifics, which makes it hard to know upfront exactly how many levels or distinct puzzle types are included before you commit.

Who Actually Benefits

This is a solid pick for anyone who wants a math-adjacent puzzle habit without the intimidation of a full brain-training subscription. Students brushing up on arithmetic and adults who enjoy number-based logic games like Sudoku will find the difficulty selector genuinely useful. The regular update cadence, with the most recent version pushed in June 2026, suggests the developer is actively maintaining the app rather than abandoning it post-launch.
