HTML WEEK – PUZZLES AND GAMES

Each example can be found in the completely refreshed and updated LAYARED Magazine!

 

We’ve got some fun that everyone can enjoy – puzzles and games! Adding some entertaining interactivity to otherwise static print makes for a more enjoyable reader experience, increasing the value of your publication.

Newspapers, magazines and other publications have long included simple crosswords, word jumbles or sudoku puzzles, but now things can get really interesting with interactive print! Check out the two examples below which can be found in the new LAYARED Magazine.

Drag-n-Drop Puzzle

The Drag-n-Drop Puzzle (found on page 8 of LAYARED Magazine) is a quick and easy way to add some fun to any kind of content. By simply cutting up an image into as many parts as you like, you can create a puzzle for readers to solve by dragging the pieces into place on their smartphone or tablet.

This example shows off the “draggable” capability of jQuery. It’s straightforward and easy for readers to understand – first you see one piece float up and snap into place, and then you have to do the same with the remaining pieces. Here’s more about this HTML example and how to make your own.

  • Puzzle Pieces are created by splitting any image of choice into desired sections.
  • Pieces are made “draggable” by using the “touch-punch” plugin explained and found here.
  • Draggable and Snap UI can be found here.
  • You could alternatively allow all puzzle pieces to be shown immediately from the beginning.
  • To create a smoother look on the Layar App, the “light beam” effect (when the puzzle is loaded) was made using only jQuery and two images of light beams.
  • The widget also offers a “Play Again?” button that refreshes the widget.

The Drag-n-Drop code may sound complex but the idea behind it is simple. First we placed a black-and-white version to serve as the area where all the puzzle pieces would end up. This doesn’t have to be done but we thought this would make it easier for users to see where they would be dropping puzzle pieces. If you want to have the puzzle snap into place above the physical image in your print content, simply remove the background image.

The way the snap feature works is one HTML “<div>” snaps onto another. For this puzzle to work, all you have to do is make one image snap onto an invisible copy of that image.

You need a piece to drag and a piece to snap onto and they need to be the same, so you just duplicate your puzzle pieces. You should have two of each piece, those for the user to drag and the others for them to snap onto. You then place the snap pieces where you want the pieces to fit together, but make them invisible, otherwise it will look as if the puzzle is already put together!

Now, when you drag the other visible pieces over the invisible ones, the drag designated pieces will snap into the correct place. Since the invisible images can’t be seen, it will look like the visible pieces are snapping into place on top of the black and white background, and presto! You’ve got a really fun and interactive puzzle game with very little effort.

Scratch-Away Game

People love scratch-away games of all kinds. The Scratch-Away Puzzle (found on page 27 of LAYARED Magazine) implements this brand of fun in AR. After scanning the page with Layar, readers simply scratch away at the puzzle to reveal the hidden message. Here’s more about this widget:

  • Uses Canvas and Javascript, which you can find here.
  • Users essentially scratch away normal image to reveal solved image below.
  • Alternatively, a drawing feature could be added so that user can “paint” onto a canvas.

The Scratch-Away Puzzle may seem like complicated code, but it isn’t. The way we use the Canvas in our demo is by first layering two images on top of one another. One is the picture you see at the beginning, and right below it is the image with the appropriate letters blurred.

When you drag your finger across the screen and “scratch” it, you are actually erasing the front image and revealing the image behind it. It’s really as simple as that. This code can, of course, be reversed or a paint element could be added to create a canvas where a user can draw anything that they want.

That’s all for Puzzles and Games found in LAYARED Magazine. These examples were built with very basic HTML tools and techniques, but can add a lot of great interactivity to your print products!
