Sure, here is a step-by-step guide on how to play Jigsaw:

Start the game by selecting a puzzle. You can choose from a variety of images, each with a different number of pieces.

Once you have selected a puzzle, the pieces will be scattered on the screen. To begin, pick a piece and drag it to where you think it fits in the puzzle.

The pieces will snap together when they are in the right position, making it easy to see which pieces are a match. Use this feature to your advantage to help you assemble the puzzle more quickly.

Continue fitting the pieces together until you have completed the puzzle. As you progress through the game, the puzzles will become more complex, with more pieces and more intricate images.

You can use special features such as "edge pieces only" mode, which allows you to focus on assembling the borders first, or "preview" mode, which displays the completed image for reference.

To make the game more challenging, you can also choose to play against the clock or compete with other players to see who can complete the puzzle the fastest.

If you get stuck, don't worry! You can use the "hint" feature to reveal a piece's correct position, or use the "shuffle" feature to randomly rearrange the pieces on the screen.

When you have completed the puzzle, you can admire your work, save your completed image, and start a new puzzle to continue challenging yourself.

And that's how you play Jigsaw! Keep in mind that the game may have additional features or variations depending on the specific version you are playing.
