Range Puzzle Online

Range is a self-contained logic puzzle built around one clear objective. Each new board gives you a fresh problem to solve, so it works well for quick sessions and repeated play.

Place black squares to limit the visible distance from each numbered cell.

Click with the left button to paint a square black, or with the right button to mark a square with a dot to indicate that you are sure it should not be painted black. Repeated clicking with either button will cycle the square through the three possible states (filled, dotted or empty) in opposite directions. You can also use the cursor keys to move around the grid squares. Pressing Return does the same as clicking with the left button, while pressing Space does the same as a right button click. Moving with the cursor keys while holding Shift will place dots in all squares that are moved through.

Most puzzles in this collection reward deduction more than speed. Focus on the most limited choices first, use the clues to narrow the board, and avoid guesses unless the puzzle mode clearly expects them.

If you want the full original rule explanation, examples, and advanced options, the official manual is the best reference.
