How to Play

Sudoku: Master the 4x4 Grid

Your goal is simple. Fill every empty cell with a number from 1 to 4 so that each row, column, and 2x2 region contains each digit exactly once. Use your mouse or tap the screen to select a cell and input your choice. You will find that learning how to play Sudoku this way is much less intimidating than the standard version.

Sudoku: Watch Your Logic

The Sudoku controls are straightforward, but do not get cocky. A common mistake is filling a cell based on a hunch rather than checking all three rules. If you see a number repeat in a row, hit the reset button before you get stuck. The later grids force you to think three moves ahead.

Who Should Play Sudoku?

You want to keep your memory sharp but hate the tedious slog of massive 9x9 grids. This is for the player who prefers high-speed logic over long, drawn-out sessions. It is the perfect pocket-sized workout for your focus.
