Number Sums is the perfect 'palate cleanser' for puzzle lovers. It takes the simplicity of basic addition and turns it into a complex logic grid that feels like a cross between Sudoku and Nonograms. The minimalistic design is a major plus—it keeps your focus entirely on the numbers and the math without unnecessary distractions.

What I appreciated most was the range of difficulty. Starting on a 3x3 grid is a nice warm-up, but the 10x10 boards require serious mental gymnastics. The toggle system for circling and erasing numbers is intuitive, allowing you to narrow down possibilities quickly. It’s an excellent way to keep your mental math sharp while enjoying a satisfying, quiet puzzle experience.

Dinsun Review

I respect a game that doesn't try to be something it’s not. Number Sums is a pure logic puzzle. It’s dry, it’s clinical, and it requires a decent amount of mental math. For someone my age who wants to keep the gears turning, it’s a solid enough choice. The interface is minimalist and gets out of the way, which I appreciate.

However, it’s not exactly a 'thrilling' experience. It’s digital homework. The difficulty spikes can be a bit jarring, and like all 'free' puzzle apps, the ad frequency is a persistent annoyance. It’s better than the water-sorting junk, but it doesn't have the timeless elegance of a well-crafted Sudoku app. It’s a good 'waiting room' game, but nothing you’d sit down and play for an hour.
