While our website offers a premium, distraction-free Sudoku experience, sometimes you need a puzzle fix on the go. If you're looking for other brain-teasing apps to complement your daily Sudoku, here are some of the best alternatives available on mobile in 2025.

1. KenKen

Often described as "Sudoku with math," KenKen uses a similar grid but requires you to use arithmetic (addition, subtraction, multiplication, division) to solve "cages" of cells. It’s a fantastic way to engage both your logical and mathematical skills.

2. Nonograms (Picross)

If you love the pure logic of Sudoku, you'll feel right at home with Nonograms. In these puzzles, you use number clues on the side of a grid to reveal a hidden pixel image. It's incredibly satisfying and exercises a different kind of deductive reasoning.

3. Kakuro

Another math-and-logic hybrid, Kakuro is often called a "mathematical crossword." The goal is to fill the grid with digits from 1 to 9 so that the sum of each horizontal or vertical block matches the clue given, with the added rule that no digit can be repeated within a block.

4. Logic Grid Puzzles

For those who love story-based deduction, classic logic grid puzzles are the perfect fit. You're given a series of clues and a grid, and you must use deduction to figure out the relationship between different items, such as which person owns which pet and lives in which house.

5. Two Dots

While less about numbers, Two Dots is a beautifully designed game about connecting dots of the same color. Later levels introduce complex mechanics that require careful planning and strategic thinking, scratching a similar itch to a well-crafted Sudoku.

While these games are fantastic, remember there's nothing quite like the pure, elegant challenge of a classic Sudoku puzzle. Happy puzzling, no matter what grid you're tackling!
