Ninigrams is an absolute masterpiece of minimalist puzzle design. Mobile storefronts are flooded with puzzle apps that overwhelm you with obnoxious pop-up ads and flashing microtransactions, but Ninigrams respects the player. It delivers a clean, incredibly smooth, and deeply relaxing logic grid environment that lets you zone out and focus.
The controls are wonderfully precise, which is a major factor for larger 20x20 grids where accidental taps can ruin a perfect run. The art style of the hidden pictures is delightful, and solving each puzzle brings a great sense of accomplishment. It has quickly become my go-to app during my morning commute.
Dinsun here. Ninigrams is precisely what it sets out to be, nothing more, nothing less. It's a clean, no-nonsense translation of traditional Picross puzzles to mobile layouts. You read the number hints along the grid borders, fill out your rows and columns, and build pixel patterns. I appreciate the total absence of aggressive live-service distractions, microtransaction banners, or mandatory internet connections—you download it, pop it into offline mode, and use your brain. It doesn't push the logic puzzle genre forward or break structural ground, but as a reliable mechanical time-killer built on pure deductive reasoning, it's solid. Good puzzle tools don't need gimmicks.
Performance: Flawless performance. Touch detection precision on small grid quadrants prevents misclicks.
Buy if: You love logical grid deduction, Picross puzzle matrices, and want a premium offline app to clear during travel.
Skip if: You require narrative development, high-end graphical fidelity, or action-based mechanics.

Always begin with the largest numbers on the grid. If a grid row is 10 cells wide and the clue is 10, fill the entire row. For numbers greater than half the grid size, calculate the overlap cells to guarantee your first correct blocks.

Using logic and basic arithmetic, players tap to fill cells or cross out empty blocks. Once every row and column aligns perfectly with its respective numeric clues, the grid animates into a full-color pixel masterpiece.
